Lithium Battery Quick Guide

Leaders in 12v technology

Independently tested in our facility, you can trust that you will get what is on the label! The nominal capacity is what is running those appliances, e.g 100Ah = 100Ah - period. At REDARC we have applied our 12v expertise to ensure our LiFePO4 batteries are the best and with a decade of extensive offroad testing, they’re perfectly suited for your caravan, camper trailer, RV or 4x4. REDARC’s LiFePO4 batteries are available in capacities ranging from 60Ah to 200Ah and include an internal BMS (battery management system) which enables the batteries to be connected in parallel to increase capacity for even longer storage. 

For an incredible amount of energy, you can parallel up to four of the 60Ah batteries, and up to six 100Ah, 100Ah-HD and 200Ah batteries*


Complete your battery management system

You can also complete your whole battery management system by including solar and connecting your battery with REDARC’s BCDC In-Vehicle Chargers available in 25amp, 40amp and 50amp variants or a Manager30 30A Battery Management System. For Total Vehicle Management, the RedVision system will enable the control and monitoring of many functions including switching devices and systems on and off, and monitoring water tank levels and battery levels***


*Batteries must be paralleled with the same model. 

**Lithium batteries are not recommended for cranking applications.

***When paired with a Manager30, RedVision will provide battery information.
