Lithium Iron Phosphate 12V 100Ah Battery, Marine Grade

SOK Battery Lithium Iron Phosphate 12V 100Ah Battery, Marine Grade

The SOK Battery SK12V100P is a 12.8V 100Ah Lithium Iron Phosphate (LiFePO4) drop-in replacement battery delivering 1280Wh of stored energy. Engineered for marine, RV, solar, and off-grid applications, it combines durable sealed plastic construction with an IP50 enclosure rating and an advanced V8 Bluetooth BMS for intelligent, maintenance-free operation. The detachable cover allows straightforward replacement of the BMS or individual cells, extending the useful life of the pack and reducing long-term ownership costs. With a 7-year warranty and a rated cycle life of 4000–8000 cycles, the SK12V100P significantly outlasts traditional lead-acid alternatives. Batteries can be connected in series (up to 4) for 24V, 36V, or 48V bank configurations, or in parallel (up to 10) to expand capacity—making the system easily scalable as power needs grow. When connecting in series, all units must be at the same state-of-charge (SOC) before connection to maintain system balance and safety.
