Yes these batteries are expensive - but for good reason. These are the highest quality lithium batteries you can find made specifically for a van or RV.

Engine Crank: These lithium batteries can provide up to 1000 amps of power to start your vehicle's engine in the case of an emergency.

Integrated Heaters: Integrated heaters for charging and discharging in up to -20C. Unlike the SOK batteries, the heaters use the battery, not the charger to power the heaters.

230 Amps of Continuous Power: One single battery can power a 3000W inverter/charger.

NeverDie® Battery Management System (BMS): The battery will shut off once it's down to 10% to ensure you never fully drain the battery. Hit the power button to turn the battery back on. The BMS is equipped with over-charge, over-discharge, short circuit, low temperature and high temperature protection.

Bluetooth or CANbus Monitoring: Monitor your battery with the Lithionics Battery iOS and Android app. Or else directly monitor via CANbus to the Cerbo GX device.

Shipping Info: The batteries will be shipped directly from the Lithionics factory. Shipping is significantly more affordable with multiple batteries.
