Yes LFP bank has a DIY BMS, any cell dropping below 2.8v and it turns off the above relay; LFP surge only limited by a ceramic fuse, 250 amps, nothing too fancy here. There was an immediate noticeable improvement on heavy loads, like a 2KW electric jug; the battery volts hardly sag, compared to the Lead Carbon battery on its own. Mike Thanks for the info.  Just curious, does your DIY BMS also handle charging protection?
