@LezT i been thinking about these 12v to 12v jump start gadgets things you can get for vehicle to vehicle
Is there any way you could make a plug that has 2 wires and crocodile clips on the other end to charge a battery in my tub when I am running about
Cheers al

Better to use the quick release battery terminals and a battery isolator for when you take it out, cheap jump cables make a great set of charging leads, just run them along the chassis, use a small amount of the Neg lead to make an earth cable and the rest of it can be added to the pos for the power connection running from Battery No 1

Yeah that's a good idea can do that was just wondering on my question as I have 12v sockets in tub trying to corner the market on 2nd battery gadget

I can do these for ya if you need them..

It's that I've never seen one and would like to give it a go we could be millionaires

Yes Del.....
