Mindstorms NXT battery pack Li-ion
Description
It is in my country impossible to get a rechargeable battery for an old Mindstorms NXT robot, so I made my own. Make sure to only use a charger that is specially made to charge these cells!!! There is no protective circuit in this pack.Only play with lithium batteries when you know what you are doing!You will need two 18650 cells, one plug terminal, two 6 mm M3 bolt and some wire and soldering stuff.
