When i play a little with some LiPo batteries for a remote controlled car, or similar, it's cheap, and don't mater if i destroy a LiPo battery, they don't cost a lot. But it is quite another thing when the battery pack will cost more tah $5000 as to the KEWET 2 runs at 48 volt.
So now it is about time to learn more about the Li Ion technology, to know more so i can make a test setup with an Arduino to monitor LiFePo battery pack.
I will use some Li Ion cells from a faulty laptop, and cram it into a small LEGO electric car or my DIY electric bicycle LiIon powered.
Basic knowledge on Li Ion batteries:
