I have a 50amp rated 12v trolling motor socket in my boat connected by a 10 foot 8awg cable to a 100 AH lipo4 battery in the bow...Is there any reason I can't connect my ip65 15 amp charger through that 12v plug to charge the battery at that extended cable length?
That will be fine... Although I wouldnt be so sure about the trolling motor...
8 AWG is about 8.5mm2 which, at best, is going to get warm at around 40A, the actual installed rating will depend on the cble type and installation method.
It is SELV of course at 12V, so unless it melts or bursts into flames, which the insurance would likely take notice of, I dont think ther are any regulations to worry about.
OF COURSE you still need to be doing things safely and correctly.
Make sure your ciruit protection is adiquate, remember a 150AH battery could dump many hundreds of amps into a faulty charger, almost cirtenly with spectacular and dangerous results.
Thanks for the assurance Alistair...FYI..the trolling motor only draws a max of 40 amps...
