The Baintech Slimline 12.8V 150Ah LiFePO4 battery delivers 1,920Wh of dependable auxiliary power in a remarkably compact 90mm slimline profile — purpose-built for installations where space is at a premium. A robust 200A Battery Management System (BMS) safeguards against overcharge, over-discharge, over-current and short-circuit events, while the integrated Bluetooth module lets you monitor state of charge, voltage, current and cell health in real time from your smartphone, without opening a hatch or lid.

Rated for more than 6,000 charge cycles at 80% depth of discharge, this battery is engineered for the long haul — ideal for 4WD touring, caravan and camper-trailer auxiliary setups, off-grid solar storage and marine house-bank applications where a slim, lightweight and high-capacity lithium solution is required. At just 11.5 kg it saves significant weight compared to equivalent AGM deep-cycle batteries, making it equally at home under a caravan bed, in a tight 4WD dual-battery tray or within a custom battery box build.
