For some outdoors activities, there’s simply never enough power to go around. That all changes with the MarCum® Max Battery. At 12V 30Ah, it's the largest Lithium LiFePO4 in its class, delivering run-times measured in days, not hours.
Whether you camp, kayak, or shelter overnight on the ice, the MarCum Max provides the ultimate battery power for any long-haul pursuit. It's equipped with a BMS circuit that protects the battery from overcharge, over-discharge, and short circuiting. The performance doesn’t stop there. It's also equipped with a multi-stage charger that gives you fast initial charges, reduced-charging when near full, and a maintain-charge cycle to prevent overcharging. The MarCum Max Kit comes complete with battery, 6-amp charger and fused charging cable.
