Custom Lithium Next Generation 620Ah Ultra Slim Lithium Battery
Custom Lithium Next Generation 620Ah Ultra Slim Lithium Battery
The Custom Lithium Next Generation 620Ah Ultra Slim Lithium Battery is a premium, high-capacity lithium solution designed for serious off-grid, touring, and mobile power applications. Built to deliver exceptional energy storage in a slim, space-saving format, this battery is ideal for 4x4 canopies, camper trailers, caravans, RVs, marine setups, and fixed off-grid systems where space efficiency and reliability are critical.
Utilising automotive-grade LiFePO₄ lithium cells, this battery provides outstanding safety, thermal stability, and long service life. The ultra-slim design allows flexible mounting options such as behind seats, under floors, or within tight cabinetry without sacrificing usable capacity.
An advanced integrated Battery Management System (BMS) actively monitors and protects the battery from over-charge, over-discharge, short circuit, over-current, and temperature extremes. This ensures consistent performance, safe operation, and compatibility with modern charging systems including solar, DC-DC chargers, and inverter setups.
