How to make an aluminium air battery selfmade homemade DIY batteries
Copy of a video from youtube user: www.youtube.com He gave me permission to post it on my channel. Please go to his channel for more on this video. Many thanks. PS: With a electrolyte made from K2CO3 and water you can get almost double the voltage, so you will get around 1.3 to 1.5 Volts per cell and also more current !
