This 12V 80Ah lithium deep cycle battery is a safer, more lightweight alternative in your application. The RB80-D is a European DIN size battery.

At 25 lbs, this battery is less than half the weight of a lead-acid equivalent, helping to fight against the drag cause by heavier options. It maintains consistent power and is equipped with handles for carrying, an M8 terminal type and a built-in battery management system (BMS). All RELiON LiFePO4 batteries have installation flexibility, fast-charging capabilities and are maintenance free.
