Converting from Alkaline, Ni-Cd, Ni-MH to Li-ion with USB charging
#1
Video 
Recently ozz93666 made me think about making a video about converting AA / AAA Alkaline, Ni-Cd, Ni-MH-powered devices to Lithium-powered ones.

I decided to show how i converted my nephew's JJRC H8 mini quadcopter's RC unit from 3S AAA Alkaline, Ni-Cd, Ni-MH to Li-ion using TC4056A charger board which i've tested some time ago. This board has integrated battery protection and output contact pads which stay active during charging. So in the end i've made the RC unit Lithium-powered, rechargeable via micro-USB and usable during charging.

Looking forward to criticism, suggestions and just comments))

Not off-topic, just in the wrong section Wink

I moved it to the correct one.

Conversion rule is simple: for any 3 AA/AAS/NiCds you can use 1 Li-ion cell.

In the case of power tools, stated voltages are more relevant than the actual number of cells: for 12V and near that you need 3 cells, for 14.4V you need 4, for 18V you need 5.
