Can't figure out my leisure battery

[RosieF]

hi folks. I just got a Bongo. Love her!!! But can't figure out the Leisure Battery. When I use the control panel and put it onto Leisure Battery, it seems to switch back to the main vehicle battery. Does this mean it's not fully charged to start with. And if so, what's the best way to charge it? Does it charge while you're driving round or do you need to plug into mains? It was converted by AVA Leisure. I'm 100% new to this camper van lark so any advice would be great. Thanks a mill. Roisin

it seems to switch back to the main vehicle battery.

What do you mean exactly ?
The normal setup has a Split Charge relay to allow charging from the vehicle alternator when driving, and a charger connected to the EHU to allow charging from the mains when on a Hook-up.

..sounds like she has a Zig unit or similar.

Rosie - how can you tell it's "switching back to the main vehicle battery" when you "switch it to leisure"?
