Meet our largest-capacity battery. The VoltX 12V 300Ah Lithium Battery provides twice the amount of power that a lead-acid battery generates within a shorter charging period. Designed for utmost efficiency and safest operation, it's fitted with an advanced battery management system and has the same non-toxic, incombustible form that all VoltX batteries are known for. With a 100% DoD rate, you get to use up every bit of this 300Ah capacity, unlike most lead-acid batteries that are usable for only half of their charge.
