RB52
12V 52Ah Lithium Deep Cycle Battery
The RB52 is a 12V 52Ah lithium marine deep cycle battery. The RB52 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.
The RB52 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.
