I was sent this 12V lithium power pack to take a look at. The owner had taken a look inside and noted that there didn't seem to be any obvious balancing or protection module for the cells. Let's take a look inside.
The measured capacity of the cells is 2,200mAh per cell, so a total of 12V at 2,200mAh or if you cheat the figures and add the cell capacities up it comes to 6,600mAh.
