These chargers do draw up to about 50% more if needed to put the rated output and voltage on the battery. So in a word, NO. You should not need an additional limit device.
Would a lithium battery thatโs being charged by a DC-DC charger thatโs limited to 50 amps output and fused on the input side at 50, 60, or even 75 amps on the input side even need an LI-BIM?

My two group 27 lead acid batteries need replacing. Even though I'm too old to get maximum benefit from lithium longevity, I am thinking about going with a single 100 AH LifePO4 lithium. Doing some research it appears that a DC - DC charger is needed between the truck alternator and camper battery to protect the alternator. Would this still be required with only one 100 AH battery? Truck is a 2006 GMC 2500HD. Also have 125w of solar.
Thanks,

Even in a TC, the charging circuit to the camper batteries is surprisingly long, and while you can minimize the voltage drop, you canโt eliminate it. Install a DC-DC charger with adequately sized wires and forget about voltage drop entirely.

This is probably a dumb question , forgive my ignorance . I have been reading about these new technology batteries , lithium and now Sio2 that can be discharged to 80 and 100 percent . How do they power equipment that requires 12v to operate like a furnace sail switch , at this state of DOD ?
