Renogy is one of the best quality brands available on the market. Their 100Ah, 12V LiFePO4 model, features a state-of-the-art BMS with high-performance dual processors that protect against:

  • Short-circuiting.
  • Overcharging.
  • Over-temperature.

Additionally, it comes with a self-heating function that protects it in cold conditions. 

Lifespan-wise, this battery can run an estimated 4000+ cycles at 80% DOD. When operating at under 50%, the number of cycles increases. 

The battery also has a protection rating of IP54, which protects against dust and some resistance against water. 

Finally, Renogy’s battery integrates an auto-balancing function that allows it to connect multiple batteries in parallel to improve the average charging efficiency over the long term. You must connect these batteries in parallel.

3. Lossigy

Max. charge current100A
Max. discharge current100A
Cycles4000 -7000
Weight24.7 lbs
Dimensions12.95 x 6.69 x 8.43 in

Lossigy’s 100Ah, 12.8V LFP deep cycle battery is another reliable option for multiple applications such as:

  • RVs. 
  • Camping.
  • Boats. 
  • Golf carts.
  • Battery banks for solar power systems.

This battery features BMS multi-protection with short-circuit and over-current protection, as well as overcharge and over-discharge protection. Moreover, the BMS system protects the battery against multiple conditions during the charging process, such as high temperatures and low/high voltages.

The IP rating of this battery is very high (IP68), capable of providing complete protection against dust and even withstanding complete immersion in water, making it the best battery available for marine applications.

4. Battle Born

Max. discharge current100A
Max. surge current200A
Weight31 lbs
Dimensions12.75 x 6.88 x 9 in
Warranty10 years

Battle Born’s LiFePO4 12V 100Ah model is exceptional as it lasts up to 5000 cycles in a best-case scenario and integrates a surge current option of up to 200A for around 30 seconds.

This is essential for all applications that require an instantaneous current higher than the maximum discharge current (which in this case is 100A), such as induction and DC motors.

This model is also water-resistant and sealed, although we advise against submerging it underwater. Additionally, it includes a BMS that provides all the protection you need to make it last longer and be safer.

An exciting feature of this battery is that it is designed with Battle Born internal heat technology that keeps a low internal draw. This keeps the battery warm and ready for charge regardless of conditions.

The heater will automatically activate when the battery’s internal temperature reaches 35℉.

5. Ampere Time

Max. charge current100A
Max. discharge current100A
Cycles4000 at 100% DOD
6000 at 80% DOD
15000 at 60% DOD
Weight‎24.2 lbs
Dimensions‎13 x 6.77 x 8.43 inch
Warranty5 years

Ampere Time is another popular brand among customers not only because of its performance but also because of its price.

The 100Ah LiFePO4 Ampere Time battery features an IP65 rating which guarantees protection against dust and some decent protection against water.

Moreover, the battery’s lifespan is over 4000 cycles at 100% DOD, which is relatively high compared to other models in the market and even in this guide. Under lower DOD ratings, the battery can reach 8000 cycles — the highest number on our list. The battery is also capable of providing 95% efficiency in energy conversion.

Another exciting feature of this battery is its surge current which reaches up to 280A for nearly 5 seconds. This is very important for starting up medium size motors.

Finally, you can connect this battery via either parallel or series connections.

6. Expert Power

Max. charge current100A
Max. discharge current100A
Weight22.6 lbs
Dimensions13 x 6.8 x 8.4 (H + Terminal: 9.3) in

Expert Power’s LiFePO4 12V 100Ah battery is another good choice for deep cycle applications. This battery has a capacity of nearly 1280Wh and has a 95% conversion efficiency.

It possesses a lifespan of up to 7000 cycles under a 50% DOD performance rating. Moreover, you can completely discharge the battery up to 100% DOD with an equivalent number of 2500 cycles.

As for electrical current ratings, you can charge the battery up to 50A and discharge it up to 100A, which is within the average range of most batteries. However, it features a surge current of 200A for 2 seconds which not all batteries can provide.

Finally, the self-discharge rate of this battery is somewhat high, reducing to 80% of its capacity under 12 months of storage at a temperature of 20C.

7. Enjoybot

Max. charge current100A
Max. discharge current100A
Weight23.8 lbs
Dimensions13 x 6.77 x 8.42 in
Warranty10 years

At approximately $0.30 per Wh, Enjoybot’s 100ah LiFePO4 offering makes for a great, cost-effective battery storage solution.

Durable, this model comes with a 10-year warranty and 4500+ cycle life. It also has some useful features, like its ability to wake itself from sleep mode.

LiFePO4 batteries enter sleep mode to protect their cells from over-discharge. In most situations, you’ll need to jump them with another 12V battery to wake them.

However, Enjoybot’s battery comes with a self-recovery feature. It can wake itself up once you’ve disconnected all chargers and loads.

Are LiFePO4 100Ah batteries good?

Lithium iron phosphate batteries offer important advantages compared to lead-acid or lithium-ion batteries. These include the following:

  • Discharge and charge efficiency: Their discharge and charge efficiencies are better. 
  • Longer lifespan: Their lifespans are longer than other deep cycle options, particularly lead-acid.
  • 100% discharge: You can discharge the battery down to 100% without causing damage to it. This is a feature that lead-acid batteries cannot beat.
  • Superior density: The energy density in LiFePO4 batteries is higher, so you can get more energy for the same volume size. Thus, the weight can drop to 50% in some cases compared to lead acid.

How Long Do LiFePO4 100Ah Batteries Last?

This is directly related to the battery’s number of cycles. It also relates to the DOD you want your battery to operate at.

A higher DOD means you’ll be able to use more energy from a single battery, but it also means that the battery won’t last as long.

Most LiFePO4 under high usage can last around 2000 cycles which is about 5 years. However, a battery could last up to 6000 cycles, which is about 15 years under moderate usage.

Why are LiFePO4 100Ah batteries so expensive?

In comparison to lead-acid batteries, LiFePO4 batteries are:

  • Lighter. 
  • Higher efficiency conversion values.
  • Higher energy density. 
  • Can be discharged up to 100% of their capacity. 
  • Safer. 
  • More eco-friendly, 
  • Last longer.
  • Lower self-discharge rates.

All of that comes at a price. In saying that, despite them being more expensive, they will last longer. Therefore you will not need to replace your battery anytime soon.

Can you use a LiFePO4 100Ah battery in your van?

You can use a 100Ah LiFePO4 for camper vans, motor homes, and sometimes even boats.

Lithium-iron phosphate batteries do not require maintenance; they last longer and can provide high currents when needed.

That said, we advise against using a single 100Ah model as a starter battery.

What can a LiFePO4 100Ah battery power?

100Ah is equivalent to 1,280Wh. Loads are determined by the amount of power they draw and their equivalent energy consumption relative to the use time.

Here are some examples of devices you can power with a 100Ah LiFePO4 battery:

  • Fans. 
  • Electronics (phones, laptops, speakers, iPads). 
  • Lights. 
  • Toasters. 
  • Microwaves. 
  • Water pumps. 
  • A refrigerator. 
  • Small cooking stoves. 
  • Blenders. 
  • TVs. 
  • Motorcycles.

However, the time you can power a load will depend on its power consumption rate (watts). The higher this is, the less time you will be able to power it.

Final thoughts

We hope our list of LiFePO4 100Ah batteries helps you navigate the overwhelming amount of battery options on the market.
