The right hind leg doesnt move much. Calibration mode (c10 x, c14 y) wont move the servos there either just a tiny blip from the board. Connections to board look ok. Same leg doesnt do much with remote commands. Are there any diagnostics I can run to test each servo?

With fully charged battery connected, starting OpenCat sketch and using the serial monitor receives repeated "low power!" messages how to diagnose? Also blue light on the battery doesnt stay on very long.....help!
