Our compact series of lithium batteries utilises cylindrical cells that have increased energy density to create a dramatic improvement in battery capacity over a given foot print. As a result the 125AH (model KS-C125B) provides greater storage in a smaller format than the equivalent super series battery, whilst the 155AH (model KS-C155B) has an identical physical footprint to the 100 and 120 super series models, the 200AH is the same physical size as the 150AH, with the 300AH model the same footprint as the 200AH Super series equivalent. The compact series has a 7 year warranty as standard.
Model KS-C125B COMPACT SERIES 125Ah 12V lithium leisure battery with integral Low temperature charge protection and Bluetooth
125Ah Lithium-iron leisure battery in a smaller compact format. Featuring smart integral BMS, Bluetooth data interface (via free KS Energy app), low temperature charge protection and over charge protection. A drop in replacement for Motorhomes, Marine, Camper vans, caravans or camping. Exceptional value. Perfect where space is limited and at a premium.
