Are LiFePO4 100Ah Batteries Good?

Yes, lithium iron phosphate batteries offer important advantages when compared to other lead-acid or lithium-ion batteries. For instance, discharge and charge efficiencies are better in LiFePO4. Lifespans are also longer than other deep cycle options, particularly longer than lead-acid.

The possibility to discharge the battery down to 100% without causing damage to the battery is a feature that lead-acid cannot compete with.

Energy density in LiFePO4 is also higher which means that you are able to get more energy for the same volume size. Thus, the weight can drop down to 50% in some cases when compared to lead acid.


How Long Do LiFePO4 100Ah Batteries Last?

This is directly related to the number of cycles of the battery. It is also related to the depth of discharge that you want your battery to work with. Higher DOD means you will be able to use more energy out of a single battery but 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, under moderate usage a battery could last up to 6000 cycles which is about 15 years.


Why Are LiFePO4 100Ah Batteries So Expensive?

As mentioned earlier, LiFePO4 batteries are less heavy, have higher efficiency conversion values, have higher energy density, can be discharged up to 100% of their capacity, are safer, more eco-friendly, last longer and have 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?

Yes. A 100Ah LiFePO4 can be used for camper vans, motor homes, and sometimes even for boats.

Lithium-iron phosphate batteries do not require maintenance, they last longer and are capable of providing high-currents when needed. However, it is not recommended that you use a single 100Ah model as a starter battery.


What Can A LiFePO4 100Ah Battery Power?

Basically, a 100Ah is equivalent to 1,280Wh. Loads can be determined by the amount of power they draw and the equivalent energy consumption in terms of time of use.

In this case, loads such as fans, electronics (phones, laptops, speakers, iPads), lights, toasters, microwaves, water pumps, a refrigerator, small cooking stove, blenders, TVs, motorcycles, and many other devices can be powered with a 100Ah LiFePO4 battery.

However, the amount of time that a load can be powered will depend on the power rate consumption (watts) of the load – the higher it is the less time you will be able to power it.
