I have just bought a solar powered trickle battery charger so I can keep my 2wd Saffs battery topped up. The garage I keep it in has no mains electricity so I am mounting it on the back of the roof and feeding the 4.0m long leads that it came with through a ventilation brick and onto my car.
It has quite a big collection panel and its fitted with a diode which stops it drawing out the battery charge and only lets a small charge in.
Anyone else got one and if so how do you find it?
