This adapter allows you to plug any Thunder Power pack up to 5S into the Ultra-Balancer, Balance Pro or Cell Spy Plus. It narrows any pins with 2.5mm spacing down to 2mm spacing.
Bought this to connect to the Balance Pro. Had a little bit of a problem with one pin wanting to come out when connecting to the Balance Pro but was able to manage it after a few tries. Now I just leave it connected so I don't have to worry about it again.
