The Starter series is the Litio Store LiFePO4 line designed for engine cranking: 12V in 18Ah, 36Ah, 55Ah and 78Ah, with cold cranking from 600A to 1800A CCA and an active BMS that works down to -20 °C.
A starter battery is not chosen on Ah but on CCA and on the lead-acid equivalence given in the datasheet: the LS12018S replaces a 45Ah lead battery, the LS12078S a 180Ah one. At the same performance weight drops by around two thirds and voltage stays stable while cranking.
They accept alternator charging up to 15.6V and survive long lay-ups without sulphation. Suitable for cars, motorcycles, agricultural machines, boats and generators.
