Charging with B2B fitted

[anonymous-user]

I need to charge both the vehicle battery and leisure battery on my van. It’s a Citroen relay and I have 240ah of lithium leisure batteries charged by a 30a B2B charger. The only other charger out back is solar. The van will be in a barn for a month so won’t have solar and won’t be running so I need to keep the batteries topped up.

Would it be ok to connect a charger to the van battery and let the B2B send some power to the leisure batteries? I’m guessing the van battery receiving power from a charger and using it for the van and leisure batteries isn’t any different to it receiving power from the alternator and doing that but I thought it wouldn’t hurt to check.
