on board charger?

[Ridgerunnr]

just bought lund 1700 2003. Nevr been used for serious fishing obviously. it has a 12v kota on it..want to upgrade to a 24v. BUT the on board charger only has wires for ONE battery to be charged..has an output of 7amps. Am i better off getting a different charger for it to hook up two batteries individually or is there a way to make if work? NOW the dumb question, does the yamaha 115 charge the starting battery?

Heres my 2 cents, put the current single bank on the starting battery and get a 2 bank for the 24 volt system when you upgrade. Yes the motor will charge when run at more than idle rpm's but if you sit alot and only make short runs you wont put much back into the battery.

Interstates and biggest you can fit, I run 27's now but when they need replaced I have room for 31's easily and thats what I'll get
