Lithium Battery Calculator
Calculate how many hours your battery will last. Based on lithium battery nominal voltage (V) = 12.8 Volts. Calculations are an approximation only. 80% DOD. Multiple charge sources (e.g. MPPT Solar, DC2DC Battery Charger) will increase battery duration.

RV & Caravan Solar Panel Calculator
Calculate how many Ah will be put back into your battery per day. Calculations are an approximation only and based on seasonal sunlight. Eg. Summer = 6 hours (20% loss for flat panels), Winter = 5 hours (40% loss for flat panels), Midway = 5.5 hours (30% loss for flat panels).
