The Remco RM12-110LFPXSL is a 12V 110Ah slimline lithium battery built with premium prismatic LiFePO₄ cells housed in a strong aluminium enclosure. Designed and assembled in Australia, it features an advanced internal battery management system that provides over-voltage, under-voltage, overcurrent, and short-circuit protection for safe and reliable operation. Weighing just 12.9 kg with dimensions of 636 x 235 x 50 mm, the ultra-slim form factor makes it ideal for tight spaces such as behind seats, on walls, or in cupboards where a conventional battery cannot fit. Capable of 100A continuous charge and discharge, with a 200A surge capacity, it delivers 1.4 kWh of usable energy and can be connected in parallel to increase capacity. Fitted with dual grey Anderson plugs for straightforward connections, the RM12-110LFPXSL is lightweight, powerful, and versatile, offering up to 2000 cycles at 80 percent depth of discharge or 5000 cycles at 50 percent. Compact and durable, it is the perfect choice for next-generation battery systems in 4WD, caravan, RV, marine, and off-grid applications.
