Victron Cyrix-Li-ct lithium battery switch

[Steve]

Hi Mike

I’m thinking of putting in a Victron Cyrix-Li-ct lithium battery switch as you just did.

Did you keep your Battery Isolation Solenoid (to keep the camper from drawing down the truck battery when the truck engine is off), or does the Cyrix-Li-ct unit protect the truck battery if the camper battery is low and wants to draw on the truck battery?

I like how it will keep the higher voltage lithium battery from back feeding to the truck battery in addition to other protections. But I’m worried that if my lithium battery gets low there is a chance that the camper might draw down the truck battery without Battery Isolation Solenoid when the engine is off.

Thanks

Great question, Steve. Can you please post this question in the article? That way this question is linked where the mod is first mentioned. Better for context.
