Re: [Electric Boats] Battery issues

 

Sounds like battery discharge through the charger when the circuit breaker trips. Nothing kills a battery like being discharged for any length of time.

I have been experiencing battery issues.  I have a 48v system (4x12 wet cell) on a fairly new trickle charger.  After only a couple of months, all four batteries had to be replaced...wouldn't take or hold a charge.  The new batteries have been in only about 6 weeks and already I am only able to get to 47.5v.  I fear the new batteries are already shot.  I have been having a problem with the shore power breaker tripping which leaves the boat with no power for several days at a time, but can't see how that would be damaging the batteries.  Can anyone give me any pointers on common problems that might be damaging the cells?

Thank you!
