Apologies if this has already been covered but on leaving to go home after our first night in our new Bongo we had a flat battery and the van wouldn't start.
We'd had the fridge on which i'm aware would have drained the leisure battery but didn't think the van battery would have been affected. Is there anything we can do to stop this happening again as we're now worried to take her out overnight in case it happens again. The conversion is a 321 away montague if that helps.
Flat batteries!

Re: Flat batteries!
You may have had something else on, either that or a faulty Split Charge Relay, as the relay should separate the two batteries to stop that happening!
Might be worth checking what is running from which battery, disconnect each in turn and then try all the different electrical items to see which there connected to!

Re: Flat batteries!
It can be tricky to ensure the two batteries are truly separate - we found several ways they were connected when we first got our second Bongo. Accessories can be the culprit. Alarms and the like might be inadvertently linking the two positives
One way around such issues is to put a sturdy switch on the positive output of the starter battery and turn the battery off when parked. If you do this buy wisely. The switch will have to handle a lot of amps.

Re: Flat batteries!
dont have double batteries,but after replacing a battery i now know is fine,and fitting an uprated alternator,it was all down to one of the two usb type chargers i had in there
Re: Flat batteries!
It shouldn't happen. Give 321 a call once you've satisfied yourself it wasn't something you did!
Did you pack anything into the driver's footwell which could have depressed the break pedal? The brake lights remain active and will drain a starter battery.
Ignition switch completely off and keys removed?
Have you got an electric control panel with switches for running off mains hookup, charging etc.? If so, what position were the switches in? (I don't know anything about these units but somebody else will )
As g8dhe says, work out what runs off which battery. When disconnecting a battery for this test, take off its earth lead. Don't need to touch its positive. Be prepared for some odd results if the charging relay is faulty, like stuff appearing to work off either battery.

Thanks guys. Got a friend who's gonna come have a look at it for me who knows electrics. Will show him your comments and see if we can get it sorted.
