Hi Jim I was just wondering how to connect one of these up to the engine batt from a rear leisure battery using one of these - presumably I need to buy eg 3m length of a certain gauge cable? if so what guage cable is it please and do I need special connectors so it can be connected to the top of the battery terminals ? also should it go to the vans original leisure battery or the second one that was added when a solar panel was fitted or does it not matter , this is keeping them both topped up and hopefully the engine one too when I buy a master ?
