Ottimo per non dover sempre attaccare e staccare la batteria dal droneA nice sturdy switch, for which I have no idea what I am going to use it for. I got it to experiment with.Great idea but poorly executed! Just had a fail!
The switch may be heavy duty but nothing else is.
These would be fine on a 2S battery pack as the balance port is three-pole. The wire gauge is too small for anything bigger, even if you don't want to use the charge port. looks about 14G.
Please HK, get some of these set up for 3S , 4S and so on, as it is really useful to be able to isolate the plane while getting ready for flight.
Having it arrive with XT60 connectors already fitted is a good thing too.
