onboard chargering system

[trom]

All the things I've been told about ONBOARD CHARGERS has been more negitive than pos, does anyboby know the real deal?? <br />It seems to me that the concept of using one's motor to charge your trolling motor battery is a good one.<br />Please-- help me make the right decision

Re: onboard chargering system

I wouldn't.......the charging system in most outboards is too fragile and is designed to look after a battery used only for starts.<br />Time is a factor too. If you use the troller batteries for 2 hours at 30 amps = 60 amp/hours. It will take a 10 amp charging system 6 hours of max RPM running to recharge battery. Thats in ideal conditions where the start battery has been isolated!!<br /><br />Bottom line is:<br />>troller battery will never get fully charged and will suffer reduced life<br />>outboard charging system will crack under the pressure of a maximum long term load and cost you rectifiers<br />> a small charger plugged in on shore will charge the battery fully over time and spare you O/B system.....<br /><br />Disregard everything here if its an external alternator system on an inboard.....
