Great thanks

goed zoals beschreven . let wel goed op de maat voor je besteld . er zijn verschillende types.

While there is officially no rules on what colour wires, and which slot those wire should go into...Regular convention (and the pictures imaged above for the product) suggest that when looking at the plug (pigs nose) the red wire, positive, is on the right, and the black is on the left.You can see the black background image, from this product in amazon has it that way.But the ones I received were the opposite way around.This was fine when I was using the pair together, but then when throwing another battery into the mix which already had this plug on it, and of course I smoked and destroyed the battery and my electronics.Yes - I could have been more careful, and thought to check... But it did not even occur to me that it might be the wrong way around - as I have never experienced it before in 10 years of tinkering with electronics.Pretty annoyed, and frustrated, and an expensive error on my behalf - all for not checking that the product supplied was as it should be.
