Got this 2 cell lipo today but there is a 4th wire on the balance plug that doesn't plug in to anything on the balance charger it just goes to a metal pad that does plug or touch anything. Will be OK to charge? Got to get a EU - Canada plug adapter for the charger before I try to charge it, I've never seen it before. Does anyone have any ideas 💡 🤔.
Got these batteries today from aliexpress but on the balance lead plug there are 4 wires instead of 3, the forth wire doesn't plug into anything, I will be charging it through the balance lead only as I only got a cheap charger for now. Can anyone tell me if it will be safe to charge? In the photo you can see the 3 pin balance plug with the extra wire going to a silver contact plate . I can't use the charger until I get a EU - Canada plug adapter. It's a 2 cell 1000 mah battery. It's for a plane!
