Drop in lithium deep cycle replacement leisure batteries

Leaders in Lithium-iron Phosphate motorhome, caravan & marine leisure batteries

Compact Series

Overview
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.
