RV LiFePO4 Battery
Five deep-capacity builds for motorhomes, caravans and camper vans — 12.8V at 230Ah to 640Ah and a 25.6V 320Ah — every one rated at 8,000 cycles and documented down to its connection limits.
RV power is a weight problem and a patience problem. The weight: this range stores up to 8.19kWh in a 59.6kg case — energy that would take several times the mass in lead-acid. The patience: at an 8,000-cycle rating (80% DOD, 25°C), these are batteries you install once and stop thinking about, season after season of nightly cycling.
The 12.8V line runs 230Ah (2.94kWh, 23.8kg), 320Ah (4.09kWh, 31.9kg), 540Ah (6.91kWh, 47.7kg) and 640Ah (8.19kWh, 59.6kg). All charge at 14.6V, cut off at 10.4V, communicate over RS485 or CAN, and support up to four units in series or parallel — with the published caveat that in communication mode, series strings are limited to two. Maximum charge and discharge currents run from 250A on the smaller cases to 300A on the 540Ah and 640Ah builds, with 600A short peaks on the two largest. The 25.6V IMP-RV24-320 serves 24V motorhome systems at 8.19kWh with a 15-unit parallel ceiling and IP54 protection.
Discharge runs down to −25°C across the range — the cold-morning figure that matters for winter touring — and every model's dimensions and weight are on its product page, because in an RV the battery locker decides what fits long before the budget does.
