I am using Ardui Mega ADK (later Arduino Nano 3.0) which runs a bluetooth board (Sparkfun BT mate silver) and a motor via an H-Bridge. Both use the 5V PIN of the Arduino.
Now I am looking forward to replace the 12V-external-DC-power-supply with a small rechargable battery. It should just have a view cm of size. Also the battery should at least hold 1-3 hours when the bluetooth device is connected.
What rechargable battery can you recommend. t should be small and powerful. Also I am not sure how the connect these batterys, LiPos etc. They should be connected to the VIN Pin of the Arduino but in fact they have some white PINs or very thick wires. What kind of adapters do I need to connect them to the Arduino?
Thanks, best regards
