I've fitted a Renogy B2B to my Hymer Exsis which comes with an EBL system. I've wired the Starter battery ( +/alternator) to the B2B input and B2B output to the EBL (starter in) with a fuse in both lines. The EBL output has been left connected to the Leisure battery. So the B2B is effectively in series as follows, Starter - B2B - EBL - Leisure with all the negatives connected together or to the chassis
Renogy instructions are not to connect the D+ wire except on a smart alternator as the unit can detect the engine running on a standeard alternator.
I've followed numerous instructions from Renogy, and Votronic and from forums such as this but I am puzzled about what to do with the Split charge relay built in to the EBL. When the engine runs this will surely connect the EBL starter input to the EBL leisure output. Is this right?.
