You have to be carefull with ebay. Photo below shows a bunch of 4S battery wires/plugs that have just arrived. Notice something?
Below is a not I wrote to the supplier.
"Hello eshop1may
The plugs I have received are not wired correctly. The black wire, which should be negative is at the opposite end from where it should be. I have attached a photo which shows 10 of your plugs (I bought 30!) and one I bought from HobbyKing. Cables from HobbyKing are always wired the same way (regardless of supplier) - otherwise things may EXPLODE. I strongly recommend you rectify the wiring on your plugs so it is the same as the rest of the world. As far as I know you are the only people on the planet to get it wrong. I repeat, if the error is not noticed by the person who buys them, your wiring arrangement makes these plugs is potentially dangerous." ... See MoreSee Less
