System fit
This is a single-case 310 Ah / 4,000 Wh house battery: 14.5 x 8.5 x 10.5 in and 63 lb. It is built to pair with inverters up to 3,000W maximum — do not connect it to a larger inverter or to parallel-connected inverters. Recommended charge current is 150A (200A max) at 14.4V, with a 13.4–13.6V float. The internal heating kit permits charging as low as -4°F, and the NeverDie reserve, Bluetooth monitoring, and RV-C CANbus telemetry listed above are all built in — there is no separate BMS box to mount.
How ordering works
Lithionics batteries are consultation-first, as the note at the top says: email us before ordering with your van, your inverter size, your charging sources (alternator, solar, shore), and what you plan to run. We confirm the battery fits your system — inverter limit, charge currents, and physical space — and then process the order. It ships free by LTL freight.
