use generator with batteries connected to trolling motor?????

[kman10]

I have two 12 volts running my trolling 24 volt 76 lb trolling motor. batteries are now going on four years (2013). last year the batteries started to die about 4 hours of constant use on low speed of five speed control. I want to know that if I should purchase a small 1200 watt generator, connect it to the battery charger for the batteries, will this continue to keep the motor running and keep batteries charged, what are the pros and cons of this thinking?
I can pick up a generator used for about $50.00. good 27/29 size batteries are $100.00
You seem to have a good knowledge of batteries hope you can help
thanks Larry

Isn't the whole idea of an electric trolling motor is that its quiet? Might as well just switch over to an outboard motor if you are going to do this.

It will not charge your batteries at 1200 watts. Most generators with a battery charging option are only about 8 amps, and that's unregulated. That's only 96 watts, your trolling motor uses much more than that.

You could, theoretically, get a higher output charger to plug into the generator, but this would be a pretty hokey, noisy, inefficient setup. Probably not all that safe in a boat either. The whole setup would cost as much as some new batteries...

You cannot charge a 24 volt system with a single output charger or generator. You would have to chsrge them one at a time.
