Earpy69 Posted January 26, 2024 Posted January 26, 2024 So got an dmr thats wired to deans and has been running on 11.1 batteries. I don’t use deans so got the tamyia adapter to put my own 11.1 1200mAh/1450 30c and the batteries got red hot within seconds when connected. I also had smoke coming from the selector switch area. so I’m guessing my batteries to put high or got the adapter be the issue.
DanBow Posted January 26, 2024 Posted January 26, 2024 Sounds like the adapter is the issue to me, like its shorting out.
Hudson Posted January 26, 2024 Posted January 26, 2024 I'm going to take a guess and say that you might have got an adapter wired up for RC cars, which will be reversed. I've had them myself, but caught it beforehand luckily, and seen plenty of people caught out by this. IIRC, the larger sized contact on the deans should go to the round contact on the mini Tamiya. Can you post a photo to confirm? Also, put the affected batteries outside somewhere safe! I believe the correct protocol is to cut off the contacts (one wire at a time) and then put it in a bucket of saltwater, but others can confirm. Nick G and Rogerborg 1 1

Funnily enough the adapter is from an rc shop as couldn’t get one from any site. From what I can see the connection in the round tamyia tuck the damage
Sewdhull Posted January 26, 2024 Posted January 26, 2024 Do you, or did you , have a MOSFET? If you did it's likely the source of the smoke. Colin Allen 1

There are some pictures here, and a suggestion on how to rewire the connector. Fingers crossed that there's not too much damage, but magic smoke escaping from electronics is rarely a good sign.
Sewdhull Posted January 26, 2024 Posted January 26, 2024 Yes it's the smoke that makes it work...let it out and it stops
Earpy69 Posted January 26, 2024 Author Posted January 26, 2024 So this would be the problem. Don’t think to Rogerborg and DanBow 1 1

You have the positive and negative reversed. 2 hours ago, Sewdhull said: Yes it's the smoke that makes it work...let it out and it stops So, if you put smoke back in it, will it start working again?
Sewdhull Posted January 26, 2024 Posted January 26, 2024 (edited) Yes, it's really hard to get it back tho, so I normally get another one already filled with smoke 1 hour ago, Earpy69 said: So this would be the problem.
