1. Weight Reduction

With the relevant state police forces cracking down on overweight camper trailers, many owners are now looking to strip out weight from their RV vehicles so they are within the legal weight limits by replacing their lead-acid batteries with Lithium Ion Phosphate – (LiFePO4) batteries which are about 25% of the weight and volume of traditional lead-acid batteries, and about 70% of the weight of AGM batteries.

This means that by swapping out lead-acid for LiFePO4 batteries, the battery capacity can be greatly increased while reducing (or at most equaling) the current volumetric space. These days with ever increasing number of electronic devices installed in modern RVs, this increase in battery capacity is very much needed.

2. Depth of Discharge (DOD)

LiFePO4 lithium batteries are typically discharged to 80%-90% on a daily basis and up to 100% in a backup situation without causing any damage.

However, lead-acid batteries can only be discharged up to 40% on a daily basis and maximum of 70% in a backup situation.

This means that LiFePO4 lithium batteries have a much greater usable capacity than traditional lead-acid or AGM batteries.

3. Higher Efficiency

LiFePO4 lithium batteries are generally >95% efficient whereas lead-acid or AGM batteries range between 80% to 85% efficiency.

This, combined with the DOD benefits of LiFePO4 compared to lead-acid or AGM batteries, make them a much more efficient option for use on caravan or RV applications.

4. Lifespan

LiFePO4 lithium batteries have a 5 year or >3000 cycle warranty when used in RV applications with CANbus communications, however lead-acid and AGM batteries typically have a 2-3 year and 500 – 600 cycle warranty.

5. No Dangerous Gases

LiFePO4 lithium batteries are sealed units and give off no toxic gases and hence can be installed within the RVs, whereas traditional lead-acid batteries give off gases while charging requiring adequate ventilation and hence restrictions of where they can be located.
