I have an 1986 Bayliner Capri with a 4 cyl onboard. I want to use a 24v trolling motor. Is there a way to charge the 24v battery with the 12 v alternator? Probably should have posted this on the electronics forum.
Gee, why not connect the batteries in parallel for charging, and in series for running the trolling motor? I would think a battery switch would be able to do that.
This is funny!...........How bout just using a good ole "On-Board Alternator" 2 bank charger? Here's Minn Kota's
It is dc-dc, yes and Minn Kota doesn't call it that, although technically that's is its internal design type. But more-over, this thing is designed for specifically charging batt's and not just a dumb stick constant voltage @ some rated output current (12V in to 24V @ 5A out for example) dc-dc power supply.
