This is a Common Sense Thunder Power Adaptor for the Ultra-Balancer (P-30C, B-14D)
This adapter allows you to plug any Thunder Power pack up to 5S into the Ultra-Balancer, Balance Pro or Cell Spy Plus. It's also ideal for use with the DBC-14's Pins2CSRC adapter and Thunder Power batteries. It narrows any pins with 2.5mm spacing down to 2mm spacing, so this adapter is also great for use with items like the Cell Shield.
