[Gem930]

I’m switching out my batteries and inverter to a 48 volt victron system.  This is obviously causing me to have to rework the 12v systems in the coach.  Most of what I need to accomplish can be done with a 48 to 12 volt Dc to dc converter (or actually 2) but the generator start system has me thinking an independent start battery might be the best option.  I suppose I could change the generator start over to the chassis batteries (as I’m going to with the slide hydraulic motors) but I fell like having its own battery may be a good idea.  I could always wire up a starter relay to the chassis batteries as a back up.  Can anybody think of a reason why I shouldn’t do this and any recommendations on a battery size. Just for fun I used my 330 cca  lawnmower battery and it seemed to start the generator fine, but it was a brand new battery.
