Probably not. LiFePO4 keep their bulk at an even 13.7V
Your lead-acid probably floats around 13.5-13.8V. the charger might pulse or occasionally go even higher to desulfate the batteries. That’d either leave your new expensive battery undercharged or worst case damaged (or have the BMS cut it off).





I miss the days when it also meant x86 and MIPS.
