What Is the Maximum Charging Current for a 100Ah Battery?

The maximum charging current for a 100Ah battery typically ranges from 20A to 50A, depending on the battery type and manufacturer specifications. For lithium batteries, a common recommendation is to charge at 0.5C to 1C, meaning 50A to 100A for faster charging, while lead-acid batteries usually recommend a lower rate of around 20A.

LIONTRON LX 12V 20Ah

The LIONTRON® Lithium Battery was especially developed as an alternative for much heavier lead acid batteries. The battery weighs only about 3kg and is very easy to transport. Due to its absolutely usable capacity, it replaces lead batteries with a capacity of up to 40Ah in practice despite its extremely light construction.

Maximum discharge current (initial current)??

Normal lead acid batteries are not happy with charging or discharging at more than 20% their C rating. Your batt bank is rated at 230Ah x 2 = 460Ah @ 12v. Your max realistic charge rate for your battery bank would be 20% of 460a = 92a. Your multi has a max charge rate of 80a, within battery specs.

Max charging current

Typical max current that you can charge a flooded lead acid battery is around 0.15C and that is usually what the battery itself will accept. You could maybe try to force 15A
