Please Note: The kit does NOT includes a battery.

Due to international postal restrictions regarding the shipping batteries I am unable to include them in the kits for buyers outside the UK.

I recommend using a 3.7V 650mAh battery, 

These are readily available on eBay and Amazon.

The kit will come supplied with the connector for the battery which will need to be added on the battery so it can be plugged into the PCB board.


UK buyers with a UK shipping address will have the option to add the Battery to their order.

Just Select - Add 3.7V 650mAh Battery - UK BUYERS ONLY.
