Charging 12v 100a lfp battery from 12v socket

[layertone]

Is there any charger / current regular I can use to charge a 12v, 100aH LFP battery from a car 12v socket without popping the fuse in the car? I think it's limited to 10amps, TIA!

This will act as a 5A "float" charger that will get your LFP battery to very nearly full. 5A/13.8V limit due to the 10A/12V limit.
