Going to Canada for fishing trip, the problem is that at the camp there is no A/C to charge TM batteries.  Looking for some ideas.  There is a genaerator but we are trying to keep its run time to a minimum.

Boat is a Nitro NX 882 -18'- With 135 Tracker.

Thanks for any ideas.

A couple of companies, Stay-N-Charge is one I think, that will charge them from the vehicle but once there, who wants for run a vehicle the lenght of time it takes to charge TM batteries, same with an Inverter that will provide and AC output from the vehicle battery, vehicle will need to be run to keep it from killing the vehicle's battery. Haven't seen any of the solar units that have the amperage to charge one, seen several maintainers but it takes a lot more current to charge the battery.

Boils down to, better find you one of those small Honda generators (they run very quitely) that will deliver at least 500 continuous watt's and take it along. If I was gonna get one of those, I would go ahead and get at least a 1000 watt, so you can use it around the house to power a small power tool if needed. The 3 - 4 amps a 500 watt unit will put out ain't gonna power much more than your charger or a small drill.

Here is a solar charger and and charge controler.

bring some xtra batteries

Didn't take the time to do the math but with one 15 watt panel producing 750 watts per week, it will probably take a half dozen or more of those panels to charge one battery in a day, and that's with the battery only at approx 50% disharge.  Since he will be probably be fishing during the day, he would have to have two sets of batteries, one charging while use one, then he's gotta hope it doesn't get cloudy.

They make it look good by their charts but you gotta think about is when you look at the fact to replace 50 amps in a 100Ah battery, that's over 600 watts, almost what one panel it rated to put out in a week.  To get that down to a day, that's about seven panals, providing it's sunny every day.   Like I said though, this is all shooting from the hip, didn't do the math but I think I'm somewhat close.
