I have a Yanmar 3YM30 with the 120A Valeo alternator and I am installing a lifepo4 bank. I plan to use a Balmar mc-612 regulator. So I am attempting to convert the alternator for external regulation. Unfortunately, this alternator has a combined regulator + brush holder, which makes the...

I would like to implement an audible alarm when the BMS takes the battery offline. conceptually, this might be a normally-closed (NC) relay taking signal from B+ to P- and the relay output could switch an alarm that takes power from B+ to B- (or uses an independent power source). When the BMS...

Hello! I see @Will Prowse loves these units :) but also see that he points out a high standby load on the inverter (15W for the 800/1000W units). Is it possible to turn the inverter off while still having the unit charge batteries via the mppt solar charger? or is the on/off button an all or...

Hello All, I have 8 100AH Fortune cells that i need to put together for a 12v system. It needs to be able to handle 200A peek loads. Normal loads will be well below 100A. I like Will's recommended JBD BMS - but capacity is limited to 120A (maybe 130A peek). So I am considering using 2 BMSs. I...

Has anyone tried this JBD 150A (200A peak) 4s lifepo4 BMS? It appears to be a 150A variant of the BMS Will recommends. Same manufacturer (JBD). Different PCB layout. No included cables - but big pads to solder your own. Same bluetooth/app support. Smaller heat sink - which is concerning.
