Engine battery State of Charge after driving with the not-so-smart alternator. (5 Viewers)

[LithiumConvert]

After driving for a couple of hours in our nice new Fiat based motorhome, the starter battery is in a state of discharge. This is by design as the regenerative braking does not work if the battery is charged.

The B2B has ensured that the leisure battery is fully charged, but the engine battery is well down, needing about 30Ah to bring it up to full charge.

So the question is:- Should I be charging it properly after every trip, if not going to used for a while and not on EHU.

Surely, lead acid batteries like to be fully charged? (even AGM starter batteries)

Sounds like you need a B2B for the engine battery. Definitely needs charging then maintaining.
