Deep cycle batteries are a type of rechargeable battery that are designed to be discharged and recharged multiple times. They are commonly used in a variety of applications, including solar power systems, wind power systems, and electric vehicles.
Deep cycle batteries are different from starting batteries (also called SLI batteries), which are designed to deliver a high current for a short period of time, like starting an engine. Deep cycle batteries, on the other hand, are designed to deliver a lower current over a longer period of time, making them ideal for applications where the battery is regularly discharged and recharged.
The most common types of deep cycle batteries are lead-acid batteries, which are widely used in a variety of applications. They are relatively inexpensive, durable, and easy to maintain, however they have a lower energy density compared to other types of batteries, and they are not as efficient in high-temperature environments. Another type of deep cycle batteries are Lithium-ion batteries, which have a higher energy density and they are more efficient in high-temperature environments, but they are more expensive and have a shorter lifespan than lead-acid batteries.
When it comes to deep cycle batteries, it’s important to choose the right type of battery for your specific application. Factors to consider include the depth of discharge (the amount of the battery’s capacity that will be used before recharging), the number of cycles the battery is expected to undergo, and the environment in which the battery will be used.
It’s also important to properly maintain deep cycle batteries, by keeping them clean, fully charged and at the right temperature. This will ensure that they last as long as possible and perform at their best.
In conclusion, deep cycle batteries are a type of rechargeable battery that are designed to be discharged and recharged multiple times. They are commonly used in solar power systems, wind power systems, and electric vehicles. The most common types of deep cycle batteries are lead-acid batteries and lithium-ion batteries. It’s important to choose the right type of battery for your specific application and properly maintain the batteries to ensure they last as long as possible.
LiFePO4, also known as lithium iron phosphate, is a type of lithium-ion battery that is commonly used in a wide range of applications, including electric vehicles, grid energy storage, and portable electronics.
One of the main advantages of LiFePO4 batteries is their high energy density, which means they can store a large amount of energy in a relatively small package. This makes them well-suited for use in electric vehicles, where space is often at a premium. Additionally, LiFePO4 batteries have a relatively long lifespan, with some manufacturers claiming that their batteries can last for over 20 years.
Another key benefit of LiFePO4 batteries is their safety. Unlike traditional lithium-ion batteries, which use a cobalt-based cathode, LiFePO4 batteries use an iron-based cathode. This makes them less susceptible to thermal runaway, a condition where a battery overheats and can potentially catch fire. Additionally, LiFePO4 batteries are less likely to experience voltage sag, a condition where the voltage drops rapidly during discharge.
In addition to the benefits above, LiFePO4 batteries also have some drawbacks. They are relatively heavy compared to other types of lithium-ion batteries, which can be a disadvantage for portable electronics. Additionally, they have a lower voltage than other types of lithium-ion batteries, which means they require more cells to achieve the same voltage.
In conclusion, LiFePO4 batteries are a type of lithium-ion battery that offers several benefits over traditional lithium-ion batteries. They have a high energy density, a long lifespan, and are relatively safe. They are commonly used in electric vehicles, grid energy storage, and portable electronics. However, they are relatively heavy and have a lower voltage than other types of lithium-ion batteries.
Off the grid living is becoming more and more popular, and with it comes an increasing need for portable energy. Vancouver’s own Royer Batteries has created the smallest and lightest Lithium battery – The Micro Smart Heated Battery – that North America has seen, that’s the perfect solution to energy needs, whether for solar off-grid homes, RVs, van-life, or marine usage. Coming with many new advantages in comparison to its old alternative, the lead acid battery, the Canadian assembled Micro Battery uses LiFePO4 chemistry and trumps it in every category while setting the stage for the future for how we store electricity.
The lead acid battery has been the traditional choice for off-grid power usage for many years, but throughout it, the battery has had faults that leave users with more stress over their electricity. Though there are different types of lead acid batteries with different strengths, the weaknesses of them all remain the same. Firstly, the lead acid battery can only use 50% (or less) of it’s rated capacity (Ah) for each cycle, leaving less usable power than advertised. For lead acid battery users this means you don’t really get what you think, energy wise – you get half of it. Furthermore, if the lead acid battery isn’t charged on a strict schedule, the lack thereof will begin to damage the battery, before it’s even used all of its power.
Cycle life – the number of times a battery can be recharged – is another issue that could be improved when it comes to lead acid batteries. At about 1500 cycles, the lead acid battery will have lost 50% capacity. Though this may still seem like a lot of cycles, it’s important to note that how much usable KWh – Kilowatt-Hour – the battery can deliver is still being reduced each cycle, meaning even before the 50% capacity loss, the lead acid battery will not be able to deliver the same amount of power even halfway into its life cycle. Overall, weighing around 4-6x times more than lithium batteries, the lead acid battery is delivering sub-optimal power, low energy density, and high maintenance needs, without even delivering longevity.
With the Micro Battery, you are truly getting what you pay for. With 100% usable capacity or depth of discharge, it overcomes the deficits of the lead acid battery, and in turn revolutionized the way off grid power is stored. The battery does not need to be constantly recharged to maintain it’s life expectancy, nor does it have the same life cycle shortage as its alternative. In comparison to the lead acid battery which loses 50% capacity over 1500 cycles, the Micro Battery comes out on top, losing only 20% capacity over a minimum of 3000 cycles, and up to 5000 in most applications. It also doesn’t lose as much capacity every cycle, ensuring you are getting the optimal amount of electricity out of your battery, every time. Over the life-time, the Micro Battery will output over 10 times the amount of usable power, greatly increasing the amount of energy a user can get out of their battery. Although it cannot be charged in 0 degrees and below, nor discharged in -20 degrees and below, the Micro Battery was designed with a low consumption automatic built-in heater, to face its weaknesses head on.
The Micro Battery not only fixes the faults of its alternative but comes with new upgrades, as well. It comes with an app that connects to the battery with Bluetooth, enabling users to not only see if there are issues with their battery, but also better understand their energy usage. This app allows users to be more energy conscious, in addition to understanding how their battery really works. Furthermore, Each battery comes with a 10 year warranty but it can easily last you up to 25 years with relevant energy density still left. The Micro Battery is completely serviceable so parts are interchangeable and exchangeable; if there is an issue out of warranty it can be repaired simply.
This battery is likely going to take the market by storm. Even with other lithium-based batteries on the market, those batteries tend to have lower kWh, up to 50% larger, up to 50% heavier, as well as have less features. With the Micro Battery, the cells are square, optimizing space. Meanwhile, weighing in at only 59 pounds, the Micro 12V 310Ah Battery is the perfect solution for mobile applications, such as van-living. Although this battery costs on average 2 times more than its lead acid alternative, over the life-time of the LiFePO4 it will cost 5 times less money per Amp-hour used.
The Micro battery will truly revolutionize the way off-grid power is used and stored. Tyrone Royer, creator of the Micro Battery from Royer Batteries, reports on how he feels about his battery and its size, saying “I just love hearing ‘No way, you can’t fit that much power in there!’” At 59 pounds 100% capacity that can be cycled up to 10000 times in its lifetime, the Micro is the best new way to store energy.
The LiFePO4 battery began with John B. Goodenough and Arumugam Manthiram. They were the first to discover the materials employed in lithium-ion batteries. Anode materials are not very suitable for use in lithium-ion batteries. This is because they’re prone to early short-circuiting.
Scientists discovered that cathode materials are better alternatives for lithium-ion batteries. And this is very clear in the LiFePO4 battery variants. Fast-forward, increasing stability, conductivity – improving all sorts of things, and poof! LiFePO4 batteries are born.
Today, there are rechargeable LiFePO4 batteries everywhere. These batteries have many useful applications – they’re used in boats, solar systems, vehicles, and more. LiFePO4 batteries are cobalt-free and cost less than most of its alternatives (over time). It’s not toxic and it lasts longer. But we’ll get to that more soon. The future holds very bright prospects for the LiFePO4 battery.
But what makes the LiFePO4 battery better?
LiFePO4 vs. Lithium Ion Batteries
Now that we know what LiFePO4 batteries are, let’s discuss what makes LiFePO4 better than lithium-ion and other lithium batteries.
The LiFePO4 battery isn’t great for wearable devices like watches. Because they have a lower energy density compared to other lithium-ion batteries. That said, for things like solar energy systems, RVs, golf carts, bass boats, and electric motorcycles, it’s the best by far. Why?
Well, for one, the cycle life of a LiFePO4 battery is over 4x that of other lithium-ion batteries.
It’s also the safest lithium battery type on the market, safer than lithium-ion and other battery types.
And last but not least, LiFePO4 batteries can not only reach 3,000-5,000 cycles or more… They can reach 100% depth of discharge (DOD). Why does that matter? Because that means, with LiFePO4 (unlike other batteries) you don’t have to worry about over-discharging your battery. Also, you can use it for a longer period of time as a result. In fact, you can use a quality LiFePO4 battery for many years longer than other battery types. It’s rated to last about 5,000 cycles. That’s roughly 10 years. So the average cost over time is much better. That’s how LiFePO4 batteries stack up vs lithium-ion.
Here’s why LiFePO4 batteries are better than not just lithium-ion, but other battery types in general:
Safe, Stable Chemistry
Lithium battery safety is important. The newsworthy “exploding” lithium-ion laptop batteries have made that clear. One of the most important advantages LiFePO4 has over other battery types is safety. LiFePO4 is the safest lithium battery type. It’s the safest of any type, actually.
Overall, LifePO4 batteries have the safest lithium chemistry. Why? Because lithium iron phosphate has better thermal and structural stability. This is something lead acid and most other battery types don’t have at the level LiFePO4 does. LiFePO4 is incombustible. It can withstand high temperatures without decomposing. It’s not prone to thermal runaway and will keep cool at room temperature.
If you subject a LiFePO4 battery to harsh temperatures or hazardous events (like short-circuiting or a crash) it won’t start a fire or explode. For those who use deep cycle LiFePO4 batteries every day in an RV, bass boat, scooter, or liftgate, this fact is comforting.
LiFePO4 batteries are already a boon to our planet because they’re rechargeable. But their eco-friendliness doesn’t stop there. Unlike lead acid and nickel oxide lithium batteries, they are non-toxic and won’t leak. You can recycle them as well. But you won’t need to do that often, since they last 5000 cycles. That means you can recharge them (at least) 5,000 times. In comparison, lead acid batteries last only 300-400 cycles.
Excellent Efficiency and Performance
You want a safe, non-toxic battery. But you also want a battery that’s going to perform well. These stats prove that LiFePO4 delivers all that and more:
Charge efficiency: a LiFePO4 battery will reach full charge in 2 hours or less.
Self-discharge rate when not in use: Only 2% per month. (Compared to 30% for lead acid batteries).
Runtime is higher than lead acid batteries/other lithium batteries.
Consistent power: the same amount of amperage even when below 50% battery life.
No maintenance is needed.
Small and Lightweight
Many factors weigh in to make LiFePO4 batteries better. Speaking of weighing–they are total lightweights. In fact, they’re almost 50% lighter than lithium manganese oxide batteries. They weigh up to 70% lighter than lead acid batteries.
When you use your LiFePO4 battery in a vehicle, this translates to less gas usage and more maneuverability. They are also compact, freeing up space on your scooter, boat, RV, or industrial application.
LiFePO4 Batteries vs. Non-Lithium Batteries
When it comes to LiFePO4 vs lithium ion, LiFePO4 is the clear winner. But how do LiFePO4 batteries compare to other rechargeable batteries on the market today?
Lead Acid Batteries
Lead acid batteries may be a bargain at first, but they’ll end up costing you more in the long run. That’s because they need constant maintenance, and you must replace them more often. A LiFePO4 battery will last 2-4x longer, with zero upkeep needed.
Like LiFePO4 batteries, gel batteries don’t need frequent recharging. They also won’t lose charge while stored. Where do gel and LiFePO4 differ? A big factor is the charging process. Gel batteries charge at a snail’s pace. Also, you must disconnect them when 100% charged to avoid ruining them.
AGM batteries will do plenty of damage to your wallet, and are at high risk of becoming damaged themselves if you drain them past 50% capacity. Maintaining them can be difficult as well. LiFePO4 Ionic lithium batteries can be discharged completely with no risk of damage.
A LiFePO4 Battery for Every Application
LiFePO4 technology has proven beneficial for a wide variety of applications. Here are a few of them:
Fishing boats and kayaks: Less charging time and longer runtime mean more time out on the water. Less weight allows for easy maneuvering and a speed boost during that high-stakes fishing competition.
Mopeds and mobility scooters: No dead weight to slow you down. Charge to less than full capacity for impromptu trips without damaging your battery.
Solar setups: Haul lightweight LiFePO4 batteries wherever life takes you (even if it’s up a mountain and far from the grid) and harness the power of the sun.
Commercial use: These batteries are the safest, toughest lithium batteries out there. So they’re great for industrial applications like floor machines, liftgates, and more.
Much more: In addition, lithium iron phosphate batteries power many other things. For example – flashlights, electronic cigarettes, radio equipment, emergency lighting and much more.
LiFePO4 Quick Answers
Is LiFePO4 the same as lithium-ion?
Not at all! The LiFePO4 battery has a cycle life of over 4x that of lithium-ion polymer batteries.
Are LiFePO4 batteries good?
Well, for starters, LiFePO4 batteries are incredibly efficient compared to traditional batteries. Not only that, they’re super-light and you can use most of your battery’s capacity without any problems. (You can only use roughly 50% with lead acid batteries. After that, the battery gets damaged.) So overall, yes, very much so – LiFePO4 batteries are great.
Can LiFePO4 catch fire?
LiFePO4 batteries are the safest of lithium batteries, because they will not catch fire, and won’t even overheat. Even if you puncture the battery it will not catch fire. This is a massive upgrade over other lithium batteries, which can overheat and catch fire.
Is LiFePO4 better than lithium-ion?
The LiFePO4 battery has the edge over lithium-ion, both in terms of cycle life (it lasts 4-5x longer), and safety. This is a key advantage because lithium-ion batteries can overheat and even catch fire, while LiFePO4 does not.
Why is LiFePO4 so expensive?
LiFePO4 batteries are usually more expensive on the front end, but cheaper long-term because they last so long. They cost more upfront because the materials used to build them are more expensive. But people still choose them over other batteries. Why? Because LiFePO4 has many advantages over other batteries. For example, they’re much lighter than lead acid and many other battery types. They’re also much safer, they last longer, and require no maintenance.
Is LiFePO4 a lipo?
No. Lifepo4 has a number of distinct advantages over Lipo, and while both are lithium chemistries, they are not the same.
What can I use LiFePO4 Batteries for?
You can use LiFePO4 batteries for the same things you’d use lead acid, AGM or other traditional batteries for. For example, you can use them to power bass boats and other marine toys. Or RVs. Or solar setups, mobility scooters, and much more.
Is LiFePO4 more dangerous than AGM or lead acid?
Nope. It’s actually quite a bit safer. And for a number of reasons, including the fact that LiFePO4 batteries don’t leak toxic fumes. And they don’t spill sulfuric acid like many other batteries (like lead acid.) And like we mentioned earlier, they don’t overheat or catch fire.
Can I leave my LiFePO4 battery on the charger?
If your LiFePO4 batteries have a battery management system, it will prevent your battery from overcharging. Our Ionic batteries all have built-in battery management systems.
What is the life expectancy of LiFePO4 batteries?
Life expectancy is one of the biggest perks, if not the biggest perk of LiFePO4. Our lithium batteries are rated to last around 5,000 cycles. That is 10 years or so (and often more), depending on usage of course. Even after those 5,000 cycles, our LiFePO4 batteries can still function at 70% capacity. And better still, you can discharge past 80% without a single issue. (Lead acid batteries tend to gas out when discharged past 50%.)
