Default How to charge battery for electric 12v winch, without tripping fuses

Ignoramus17560 fired this volley in
:

I do realize that I can just wire a resistor in series, and I do have
a 1.4 ohm, 290 watt resistor and some others, but I was hoping for
something more elegant.

Thanks

You could replace the control contactor with a double-pole affair that
breaks from the charging circuit before making to the motor.

But why? You'd something in the vicinity of a 3A 'slow charge' with that
resistor on a nearly-dead battery.

And what's more 'elegant' than a one-component, no-moving-parts solution?
That resistor is over 20 times larger than necessary, but you can be sure
it won't burn out from overheating!
