Double the Capacity, Same Reliable 100A BMS: Get two DUMFUME 12V 150Ah Max LiFePO4 batteries with automotive-grade cells and 100A BMS each. Connect in parallel for 300Ah total capacity or in series for 24V/150Ah. The BMS in each unit independently protects against overcharge, over-discharge, over-current, short circuit, and temperature extremes. Each battery measures 10.04′′×7.68′′×9.84′′ and weighs 43.0 lbs. Two units take little more space than one lead-acid battery, yet deliver twice the usable energy. for upgrading your DUMFUME 12v deep cycle battery bank in RVs, solar sheds, or tiny homes. Build Massive 48V Storage with 4S4P: Two batteries are just the start. This DUMFUME 12v lithium battery series supports up to 4S4P (16 units max). Combine two packs with additional units to create a 48V system reaching 30.72kWh total energy and 19.2kW load power. suited to whole-home backup, large solar farms, or workshop power. Each DUMFUME 12V 150Ah lithium battery has independent low-temperature cut-off. Charging halts below 32°F, discharging down to -4°F. When temperatures rise above 32°F, both batteries auto-resume. Keep your off-grid system powered through freezing months without worry. No separate heating pads needed. Energy Storage Only, Not for Starting:This twin pack of DUMFUME dumfume 150ah batteries is for deep cycle energy storage only – RVs, solar, off-grid homes, marine house banks. Do not use for engine starting or golf cart propulsion. Need starter batteries?
