FAQ
Q: Is it Flat Top or Button Top?
A: It is a standard Flat Top design. Please confirm your device's spring contacts can reach the positive terminal before purchasing.

A: Not recommended. Gimbal stabilizers usually require 37.5mm batteries with built-in PCBs. This model is 35mm and unprotected, and will not fit properly.
