Largest Lithium AMP Hour Battery - 2023 Arctic Fox 865

Golden_HVAC,

The best way to limit current may be a dc to DC converter (or charger). That allows for optimization of the charging voltage, too.

When I had 875 amp-hours of lead acid batteries I'd observe over 70 amps of charging. That was not so good for my oem alternator, though it did not fail.

I do have a dc to DC unit installed now--for other reasons, but it does limit charging current on the output side to 20 amps @ 14.7 volts. There are dip switches to set the voltage.
