Refering to the diagonal parallel wiring diagram below. I have 4x UltraMax 100Ah 24V LiFePo4 batteries with their own internal BMS's ("drop in" type batteries which do not speak Victron) which have replaced a flooded lead acid bank.
My question is, for this new LiFePo4 bank, should I install fuses in-between each individual LiFePo4 battery on their positive leg? I have been unable to clarify if this is a requirement or not, or if it's safe to rely on the internal BMS for overload protection etc. I have a fuse on the main positive leg coming from the bank going to the load.
