I agree that there must be something wrong with the charging system which could be easily checked with a Volt meter. I am running a single 6V Pos earth Optima in my 38 Twelve and it appears to be entirely adequate. A bonus was that there was sufficient room in the battery holder to put a 12 Volt Gel battery, which I run as Negative earth to the Cigar lighter for GPS, Dash cam and other 12 Volt accessories. I use a 6v and 12 V battery minder for each system and plug in under the running board. Peter Toet
