I am building a LIFEPO4 system on my 28ft sailboat utilizing your LIFEPO4 150ah battery and your BMS 12/200. For vessel safety I must be able to start the engine using house batteries in an emergency.This could also be accomplished by some sort of start assist which is not available on the BMS 12/200. Can I just place a switched negative to the starter on the LB side of the 12/200? ofCould you please address this with a suggested wiring diagram.
