A couple questions on updating the firmware. I just recently purchased another battery to add to the others that are over a year old. I haven't updated the firmware on any of them as I really haven't had any issues, they all top balance fine and are usually at the same voltages. I have them in EG4 settings so they are BMS controlled by the inverter. The big question should I update the firmware, how do you know what version is on them now, and I see the latest is version 3.37, what am I missing by not updating. Thanks,
