|recharging trolling motor batteries?

No... but I'd like to hear other folks experiences using solar float
charging...
Solar float charging seems to work well. I haven't tried it myself
but have heard a lot of success stories. A small, inexpensive panel
is all you need unless there is a lot of leakage in the electrical
system.

Recharging a trolling motor is a different matter since serious amps
are required. You have to calculate how many amp-hours need to be
replaced, and how much daylight time you have available. Most people
also recommend derating the panel capacity by at least 50% to allow
for all the inefficiencies that creep in to the process.


I found a few websites - look the figures from my 24Vdc motor, added a
few things up and it comes to roughly $4,000 and that's conservative.

Think I'm going in a different direction. :)


Yeah, like a Wal-Mart battery charger!!!!!


Well, that's kind of the problem - no power to run the charger. I
have an on-board charger.
