Brand new Powerful 9 volt 4.2 watt Monocrystalline solar panel battery charger for charging both 6v and 7.2v batteries,these come wired with 3m of bare ended cable and are capable of charging all 6v and 7.2v lead acid, nicad and nimh batteries at a rate of up to around 460ma in bright sunshine,these panels are constructed of monocrystalline cells which are regarded by many as the most efficient cells available for solar charging as they will continue to emit a charge under cloud cover also,they are a tiny size measuring approx 200 x 130mm and weigh under 200 grammes and are also very tough and waterproof,there are solder terminals that the wiring is connected to on the rear but theseshouldnt get wet and we cover these in plasticseal 60 to give some protection just in case moisture does reach the rear of the panel though if the panel is stuck down this shouldnt be an issue.
