Correct VSR relay for 2 or 3 100Ah batteries?


New member

I've managed to find a single passenger seat and I can fit 2x 100Ah batteries in there. I think I might get a third one in a couple of months.. The van is an '09 313Cdi (a thread said 88A alternator). So what VSR would I need for 2 or 3 batteries?

I'm sure it's been asked a million times but I can't seem to find an answer. It seems easy to find out about everything else and I've got an electrician willing to help a little bit, but I don't want to call on him until I really need to. Or at least until I have a load of materials for him to help me with.

Thanks in advance, Tom.

Edit - For the moment it's just for a fan, lights and charging phones and ipads. Eventually I hope to have a diesel heater, water pump, extractor fan and a 3 way fridge.
