Yes, I used to do that and worked well for me. I recommend that approach when no other way can do it.

Re: Merged LiFeYPO4 1000Ah Winston prismatic cells and all electric galley...

Having Winston cells, that is what I thought initially. But some (cheaper) cells with large variance in internal resistance and other parameters will need it.


Yes. Field disconnect is the...

Re: Merged LiFeYPO4 1000Ah Winston prismatic cells and all electric galley...

Both TAO and REC BMS can remotely command external equipment either by wire or CAN bus (in addition to relays) - so no current limit.
I would add Electrodacus to the BMS comparison chart, but I have...

I think it is important for...

Re: Merged LiFeYPO4 1000Ah Winston prismatic cells and all electric galley...

You may want to look at the TAO BMS with 6 programmable relay outputs. Each can be activated by one or more criteria on cell voltage, temperature or SOC.
For example I turn the water heater ON...
