Hi Guys,

 

Just looking for some help on adding a second leisure battery.

 

I already have a leisure battery installed which is connected to the split charge relay, but as I don't do a lot of miles over 2 weeks of the month due to the location of my work, I found that it wasn't lasting until I got back to my other work which is an hours drive away.

So I decided to buy another leisure battery for the lad that's with me, in the hope that it will last till we travel to the other work, what I don't know is, can I just connect the second battery to the split charge relay? or do I connect the batteries together, i.e. in parallel  + to + and - to - then connect the relay to the positive of one battery and the negative of the other battery? any information would be greatly appreciated. This is the relay I use.

Those relays have a permanent out and 2 “switched” outs.  Connect one battery to one output, and the other to the other out.  This way, draining one battery will not drain the second battery.    Assuming you have 2 pump controllers.   If not, fit a selector switch to change between batteries.    

The 2 terminals marked “12v”. Both go to your van battery.

0v to ground of van

From memory, 6 and 4 are switched

where as 2 is permanent
