I did something dumb and my charger went POOF FML what I do?

Well I done did my first POOF EVENT! Here’s the sequence of events and I’d like to know what happened and if this charger is garbage or not.

  1. OK, so first I noticed the charge thingie on my BKB 12s2p must’ve gotten lost during a ride and just the connector was hanging there

  2. I grabbed my 12s charger

  1. I remembered I had a charging piece that connects here with the right size for my charger from my wowgo mini (which runs on a 10s battery…) so I grabbed that (the whole enclosure piece since the charging port is glued to it) and connected it to the battery. Then I plugged my 12s charger into that port

  1. First big spark, then a couple seconds later POOF and SMOKE from the charger. It stops working.

  2. I open up the charger and nothing looks fried but I have no idea what to look for…Unless all that oozing stuff that seems like glue isn’t supposed to be there…

Wellp, clearly something about that 10s charging port wasn’t compatible with that 12s charger…Is this charger garbage? How can I find the damage and what exactly did I do? Thanks ya’ll. Fuckin nOOb night. On the plus side my battery is fine!

Your red Jst connector is plugged in backwards, possitive to negative. I made the same mistake one time



well fml. So what exactly happened, electricity wise, when I did that? And is this charger Toast McGhost?

It caused a short, can you pull apart that connector? It might have melted shut

yeah for sure it pulls apart no problem there doesn’t seem to be any damage at all to the JST’s

The initial spark came from the connection of the charger to the charging port

Flip the jst connector and make sure its plugged in correctly. Not sure if you should try again after that tho, maybe someone else will be able to chime in

I’m mostly just trying to solve the charger issue now - like figure out if it’s salvageable. Because rn the charger doesn’t work, which is seperate from the jst issue

Did you match red/red and black/black? Looks like it shorted.


yeah i definitely did not as in i shorted it. Can the charger be fixed do you know or is it toast?

Hard to say, do you have a continuity tester?

i do. I’ll start probing around but I’m not sure what the best spots to test are? Pretty nOOb with electricity stuff =/

Disconnect the jst connector and disconnect your charger from wall outlet. Then plug your charger back into the 2.5mm charging port and test for continuity between possitive and negative in the jst connector. This will tell you if the charger is shorted on the inside. MAKE SURE YOU DO THIS WITH THE CHARGER UNPLUGGED FROM THE WALL

wait but I don’t care about that JST connector, it’s seperate from the charging unit itself. The JST is connected to the charging PORT. The charger is independent of that. Does that make sense?

Ah yes it appears someone came in your charger.

the most half assed potting attempt.

My laptop actually has some mad coil wine I should squirt some up in there.

Yes, but it’s very hard to test for a short using the 2.5mm connector that goes to the charger. The jst extension will simply make it easier to test I’m not familiar with how the negative and positive are separated on that round connector.
