Hi Folks, a question for the tecnically minded among you. A friend tells me that it's important that the engine starter battery is of the same Ah as the leisure Battery, his reasoning for this is, that if the starter battery is less Ah, say 90Ah, and the leisure is 110Ah, that once the 90 is reached, the charging will cease, and not fully charge the 110 Ah one.

You could mention boats often run 1000Ah+ house banks with a split charging ~80Ah starter.
