Our recheargeable Lithium batttery can replace 500 sets of alkaline batteries while producing 23 times less carbon emmisions.

If that is not a good enough reason to use it, wait there is more!

You can recharge it in 2 hrs with a USB connection and it will power your micro:bit for 5 days or more!

But wait there is even more!

If you have no power, connect the solar panel and the free sun energy will replenish your battery in 16 hrs of sunlight.

Yes, there is even more.  I left the best for last.

Look at the picture, what are those connections to the BBC micro:bit?
