At 10.2in x 6.6in x 8.2in and 23.2 lbs it fits most BCI Group 24 battery boxes while delivering 12.8V and 100Ah from A+ grade cells, which the reviewer found reassuring for long-term energy storage projects.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Group 24 size:\u003c\/strong\u003e The 10.2in x 6.6in x 8.2in footprint and 23.2 lb weight make it easy to install in standard BCI Group 24 battery boxes and tight compartments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh cycle life:\u003c\/strong\u003e A+ grade LiFePO4 chemistry is rated for up to 15,000 cycles, which translates to many years of regular use for RVs, boats and stationary storage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in 100A BMS:\u003c\/strong\u003e Integrated battery management offers overcurrent and safety protection with automatic disconnect behavior to protect the cells and connected equipment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide temperature range:\u003c\/strong\u003e Operates from -4F (-20C) up to 158F (70C), so it adapts to chilly winters and hot summer installations without premature degradation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible expansion:\u003c\/strong\u003e Can be connected up to 4 in series or 4 packs in parallel, allowing larger systems up to the quoted combined capacity for multi-battery setups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety certifications:\u003c\/strong\u003e Holds SDS\/UN38.3\/FCC\/CE\/ROHS certifications, giving practical reassurance for transport and indoor installations.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis battery is well suited to RV owners, boaters and small off-grid systems that need a durable, lightweight replacement for lead-acid Group 24 batteries and want the long cycle life of LiFePO4 chemistry.
