Anyone install it?
My existing BIM has Chassis and Coach Battery Feeds, plus Ground, Ignition, GenSet and Switch allowing you top bridge between Chassis and Coach Batteries for starting assist.
The new Lithium one has Chass and Coach Battery Feeds, Ignition, Ground and Switch.

Anyone install this and know how I'm supposed to handle the Switch-GenSet/Start Assist?

Thanks

That is an interesting product. I don't have experience with it so can't recommend either way. Just skimming the description, I can't really find a a large fault with it...... However, it does appear that it will turn on and let your lithium bank assist in starting the engine. Depending on the state of the starter battery and the specs on the lithium battery, this could put a pretty high surge on the lithium.

I think these replace the standard battery isolator solonoid they used to install in RV's.
I was just going to disconnect the house battery cable from the isolator and install a DC to DC charger instead.
As long as my starting battery stays up I'm golden. And I was going to move my genset over to the chassis batt as well so it doesn't rely on the house battery to start. Replace the converter-charger unit with lithium compatibility.

Some YT vids out there on these units.
