Had to use my emergency start today, this is a switch i have that can pull the leisure batteries into the vehicle starting circuit. Seems that in 3 weeks of inactivity something has drained the vehicle battery, it was completely dead.

My leisure batteries are kept topped up by two massive solar panels on my roof, it seems that even in mushroom growing Wales there is enough light to keep my leisures in tip top charge.

How can I rig it so that my solar panels will drip a bit of juice into my vehicle battery as well?

Hi jim Battery master about £70, eddievanbitz flogs them. Or the cheap way a suitable wire between the positive terminals with a 20amp fuse in it. Just remember to pull the fuse before you start up.

Yes you could, but to be on the safe side I would rather fit the Battery Master.. at £44.50 ..

I believe Lidl have a device that I bought in Spain last winter currently for sale, not sure when though.

It is a lead with a cig light plug at each end and a control box that lets you know whats going on. A lot cheaper than a battery master & I used it all the time I had my RV because the batteries seem to be independatly wired, except when driving.
This solved the same problem for me & kept my battery charged for 6 weeks. ::bigsmile:

It would only work if your cig lighter is live with the ignition off surly

Yes you are right if it was a European, but I think you will find RV's sockets are live when ignition is switched off, at least mine were.:thumb:

Jim,

Have you read the manual that came with your new solar panel regulator thingy?

My regulator thingy charges bank 1 (leisure) and when full, switches to bank 2, Engine/Chassis).

You may find that yours can do similar??

Hi Jim whats not safe about it? worst that can happen is the fuse blows.

Olley
Hi Olley
Bad choice of word, correct, it's not unsafe from a 'safety' point for charging but if you forget to remove the fuse on site and are not on ehu the engine battery could end up flat.. my meaning was to 'play it safe' and not have this happen.
