Generator for Trolling Motor Battery

[pickardjw]

Any recommendations on a generator to charge the trolling motor battery on multi-day off grid fishing trips? Preferably something on the cheaper side, especially since I just dropped $400 on the trolling motor battery...

That shouldn't take much of a generator just to run a charger.  How many watts? 

I have a Champion 1500 portable that's worked well for me.  I think it was less than $200, probably more now.

Trapper John has one for sale, just lowered the asking price.

Yeah I saw trapper John’s for sale, hoping for something smaller and lighter. It’s a 90aH 12v so not sure what would be the best wattage for charging it. Electricity is a weak point of mine. Ya know, 220, 221 whatever it takes.

Smaller and lighter equals more money. That’s a good deal, just leave it on your truck on trips.👍

I do a few trips every year where I take the boat across the lake and dispersed camp, so leaving it in the truck isn't ideal. And the boat's only 14' so not a ton of space.

Someone told me Ryobi had a $500 one but looks like it's $800. That Champion 1500 is $500 at camping world and seems like it would fit the bill. I think my battery charger is a 15 amp, no clue how that translates to what wattage I need but google says 600w-800w, so 1500w should be plenty I assume.

Volts x Amps = Watts. So 15A @ 15V (most chargers charge at somewhere around 15 volts) = 225W. So pretty much any old generator will work for you. I would recommend an inverter generator with an eco throttle. That way the generator can vary speed to match the load. It will run more efficiently and quieter while feeding the small load of the charger. I have a little Honda eu1000 that is very nice. It’s more than you want to spend, but Honda generators are super easy keepers and last a long time.

I have several thousand hours on my Honda 2000 generator and it is super quiet.  Sometimes I forget it is on.  For the money it is hard to beat.
Mine is older and doesn't have the bluetooth on it.

surprisly ive heard the Harbor frieght Predator ones are pretty darn good.  If it gets stolen you are not out much either

[pickardjw]

Harbor freight looks like a competitor to the Champion, good to have options to compare. Definitely on a harbor freight budget right now haha

Charged many of boat batteries with a small Honda 2000. Nowdays, I would buy the Harbor Feight equivalent for much cheaper.

For $500 you could get another lithium battery that is smaller, lighter than a genny. Unless you're talking like 3+ days, that's what I would consider.

 . This is what I would do

I have a 14ft boat that's probably similar to yours.  If I was doing what you're talking about, I'd only consider taking an inverter generator.  A conventional generator would be a PITA to haul around on the boat.

Or for about $300 you can get a very nice, used 2 hp Yamaha outboard. Lots of them on Cl…. They have a built in 1/3 gal tank that’ll run full throttle for about an hour at full throttle. A 1 gal jerry can will last for days at trolling speed. Super reliable too. Weighs 22 pounds. Old school rules!
