Long time ago this posting is done. I don't have an answer. But more a related question.
I would like to install a bi-stable relais. I was think about: https://www.whisperpower.com/remote-battery-switch-12-v-500-a. But this one needs 4 Amp when switching. Is the Active -BMS with REC Pre-charge unit capabele to drive this relay ? Or has someone a better suggestion for a bi-stable relay ?
Thanks for your reaction !

@Gerard a little late this answer
The relay in your link, use lesser as 100uAmp, in on position, and a few mAmp at the control wire.
The amps for switching the relay, 4-7amp, comes from the big m10 contacts.
REC has different type off precharge unit, old and new model.
You need to check or the precharge unit gives a positive signal to control, the Whisper/TBS relay.
This Wispher/TBS relay, you can use it as 2 wire control, same as a real latching relay.
Or, "control with one wire", as a normal style relay.
I use this relays with one wire control, is better in my view.
