Reliable Starts Under Heavy Load The built-in 200A BMS keeps your 300Ah lithium battery stable while appliances, inverters, and onboard systems draw continuous power. It also supports short bursts of up to 1,500 CCA, giving this Vatrer 12V 300Ah lithium battery the deep-cycle performance and starting capability expected from a marine starting battery. Protection against overcharging, overdischarging, overcurrent, short circuits, high temperatures, and low temperatures helps prevent unexpected shutdowns and battery damage.
