I buyed from banggood, and I have a new one, I soldered some wires to my board, and you can make the union by nickel strips 1x BMS and 2X cables imagem

Maybe look a little bad, but it’s fixed, I tried to pull, and nothing, but if you prefer I can take off,I just stay like this because, half at work is done. And the cables are biger than the area to join. I should use cables with half diameter, because the connection to BMS are by double connection.

A lot of fried things… I guess better not to ask how that happened :grimacing: But for what this small pieces of wire soldered together?

#10

Don’t know but id assume he didnt have a wire long enough so he made one?? Lol

Back on topic. Make sure you make good solid solders!!!

#13

Ain’t that your shorted bms?

#14

Wait a minute. You shorted a bms a few days ago. Is this one? If It is you can’t sell as new and you must tell in the description that It could be damaged.

#15

the BMS that i shorted was, my new BMS, and i saw with attention and didn’t damaged the BMS.

The only problem, i think this BMS have is, when the batteries are full you can’t brake. I’m not sure, but one guy tell me that on one topic.
