I would like to charge the TM battery from my outboard’s alternator.
My outboard’s alternator has 17 amps net available for charging batteries. Because my primary use is trolling, my outboard is running most of the time I’m on the water.
I would use an Automatic Charging Relay to manage charging both batteries.
My question is twofold. First, is my outboard’s 17 charging amps sufficient to maintain two 12V batteries? Second, is there is any reason not to charge the starter battery and the TM deep cycle battery at the same time from my outboard?
Thanks for any help you can offer.
