I have 3 amp trip lite dc power supply that puts out 13.8 V.
When my batteries are out of my boat during winter, any reason why I shouldn't use this for 12 V power on the boat?....as in drop the battery switch pos and neg leads on to the power supply terminals and plug it in?
I know 3 amps isn't much but all I'd be using would be radio, lights, CD player, propane sniffer/switch etc.
Is your boat IN or OUT of the water during winter??
Only reason I ask is that, if it's this one
and you're IN the water, you'll need to make sure that the -ve terminal is isolated from earth or you could end up with electrolysis issues..
If you've got power available (and obviously you have), is there any reason you couldn't leave the batteries in the boat and simply hook up a battery charger to both charge the batteries and do what you want them to do??
