Victron B2B again!

[Robb]

Hi, I know this topic has been covered before, but despite looking at previous posts I can't see a solution for my EC600 Sargent control panel?

I installed a new Lithium 110ah battery today with a Victron B2B 30 amp charger and a Solar controller, all worked well until about 30 seconds after engine start when the 30 amp breaker tripped on the Lithium side. I guess I need to add a relay or switch to the Sargent side, but not sure where to start looking for the wires as I have no wiring diagram for the van and can't find one online. Any advice would be welcomed.

Thank You Stanbrook! I'll study it in the morning.

Maybe a bigger breaker.

Just a thaught.

30 Amp B2B plus solar = more than the breaker can take over a period of time.

Is the Lithium battery a replacement for the existing leisure battery, or is it an additional battery? Is the 30A breaker instead of the original leisure battery fuse? What was/is the value of the original leisure battery fuse? Did you wire the B2B directly from the starter battery to the leisure battery? If so did you disable the split charge relay?

Hi Auto, Thanks for the reply! It seems like I need to learn lots about Lithium! Any advice is welcomed!

This weekend I dropped in a Eco110amp Lithium battery and a B2B 30amp charger, but to the same Sargent circuit. I've also added a Victron solar controller to the Sargent circuit, maybe this is wrong? Tomorrow I plan to add a 240v battery Victron charger to the system, should I slow down?
