Common Sense RC One Piece Adapter Plug (T-Style Male to Traxxas Female) (2)

bought these to use on a traxxas battery and they werked perfect, would buy again

Junk! While I was on my boat, the adapter plug melted and caught on fire. Lucky it didn't burned the battery or the ESC. Had to pry it out and solder the dean connector.

This thing looks pretty solid built at first glance. However, putting them on a brand new Gens Ace Shorty 4600mah battery with deans connector and charge on Traxxas EZ Peak Plus, it won't charge at all! I make sure the balance charging connector is secured in place on the charger but still the charger won't recognize the battery and the 4A LED will flash to issue the error message.

Get hold of multimeter to measure the balance port and +- port on the battery and see reasonable voltage 3.8V and 7.6V. I then tend to believe EZ peak charger might have some issue so searched on YouTube to see there are many people having success charging Gens Ace battery with EZ peak charger. I almost pulled a trigger on purchasing a Protek charger and Protek shorty LIPO but finally I decided to give it a try by prying the metal contact upward a little bit inside the adaptor plastic housing. That is the magic and now the charger can recognize the battery and starts charging once plugged in.

However, now the adatpor won't plug into the male traxxas connector on the ESC, just because the slightly tilted metal contact inside the adaptor is in the way. I compared the traxxas female connector and this adaptor, both of which are supposed to work the same. I found the traxxas female connector has metal contact on both sides inside the plastic housing, which can "pinch" the male connector to have solid conductivity. This adaptor does not, which might explain why the charger won't recognize it maybe because of the bad metal2metal contact in the first place.

Anyway I do not recommend this product.
