I have an RV setup with 4 7 yr. old Battle born 12v 100AH LiFePO4 batteries. One of my batteries is at 30% state of charge and won't go any higher, the rest are reading 99% SOC. I have used the Victron stand alone charger to charge each one individually. I use a Victron 3000w inverter/charger in my system. My question is can I just replace the failed battery with a new Li time 100 AH, or is there a better option for me now.
