No split charge .........How it basically happened , a year ago this very day as it happens , my van battery let me down and my leisure battery was beginning to do the same , Spruce dropped into conversation that Numax did this multifunction battery , I decided to get the Numax and fit it as the van battery and run my system off it aswell , being as I was toying with solar charging at the time I thought it might be a good idea to link it all and see what happened .
The result has been that the battery has not been out of the van to charge for a year today !
And now it also runs the diesel heater too , Im doing 6 hours every day with the pump and heater constantly going and running the vans needs too , plus I am getting home fully charged .
