back in october I ordered a battery box, but never received it (sold out)..and got my money back,
so I made my own one, just as a quick and simple solution..
its since 2 months in use now and works perfect,
was even for one hour under water for testing, without batteries.. :-),and stayed completely dry…
the high capacity batteries take some time to charge (outside of the box), but runtime is really good !! no comparison to the original batteries which burned my floor..
