I don't like only having one or two of anything. I have solar, I have a generator, 4 actually. I'll get right to it.

What I'm looking for is a way to charge my batteries outside the "loop". I want to be able to plug my little (2k Ryobi) generator straight to my bank and fire 20-30 amps at em. Does anyone know of a stand alone charger that will actually do this? I've tested a few and no-go. I know automotive chargers have different values that aren't adjustable. I've searched the internet and haven't found much and nothing off the shelf will perform this task.

thanks folks

    during irma here in north florida it was pretty dark the first couple of days after power went out and i used my automotive charger to do exactly that off the generator .. a decent one generally has 3 settings low-med-and high .. just be sure to use your multimeter and babysit it while you juice them for a few ..

    Would something like an Iota battery charger work for you?
