Why do some Lipos have 3 wires vs. 4 wires balancing plug?
I searched and couldn't find the answer to this. I have a 2s Lipo Thunder Power that has 4 balancing wires while a Turnigy 2s has three balancing wires. Other Lipos I've seen also has 3.
It makes sense to have three since they represent the front, middle and back ends of 2 batteries connected in series. So what about 4? I don't get it... Can someone explain?
As always, thanks in advance...
