Description
PCB dimensions specifically designed to fit inside a gutted AA battery box with a 1200mAh flat Lipo battery. Using Trond BT Duo 1 for inspiration as that PCB fits perfectly within a AA battery box. Maximum dimensions of a gutted AA battery box with on/off switch is 53mmX30mmX14mm. Some specific 1200mah lipo batteries can fit inside a 30mm width so that is the maximum capacity.
