Description

The RB75 is a 12V 50Ah lithium marine deep cycle battery. The RB75 offers abundant power in a small footprint. It’s versatile and compact enough to be used in many marine applications including smaller boats with lower battery requirements, boats that require two of the same batteries and boats with electrical systems designed for just one battery. Equivalent BCI size: Group 24

The RB75 is a lithium iron phosphate (LiFePO4) battery with more power, less weight and up to 10x longer life than its lead-acid counterparts. Lithium is the logical choice for marine applications where you need a longer run time and reliability. RELiON lithium batteries provide more energy for high consumption than traditional lead-acid batteries. Lead-acid batteries also need to be maintained. If they are not maintained properly, their life span is shortened. Because lithium batteries require no active maintenance, a one-time purchase guarantees better lifetime value.

RELiON lithium batteries provide more energy for high consumption than traditional lead-acid batteries. They also offer ultra-fast charging and discharging, high efficiency and a longer cycle life – plus no maintenance!

Not all lithium batteries are created equal. All RELiON Batteries use the safest and most stable components, including a LiFePO4 cathode and a built-in Battery Management System (BMS). The BMS ensures a long lifetime, safe handling – and high-accuracy State of Charge (SOC) calculations.
