Okay so I just got two new Zippy 3S 5000mah batteries in the mail today. After some past experiences, I’ve come to fear connecting two lipos together in series.
Anyways, I chopped off the bullet connector and put a couple of Dean’s plugs onto the batteries. Then I plugged the series cable with no issues, but when I plugged the balance leads to the 3S to 6S adapter it went up in sparks and now the balance lead on one of the batteries is burned.
Here is what the adapter looks like:
Did I need to cut one of the wires on the adapter?
With all that said, is it still safe to use one or both batteries? Or do I have to get new ones?
