This is the first of my semiconductor based battery testers. It's a TEC-02 Ver 3.0 unit.
I purchased mine on eBay as a 5V Lithium Li-ion LiFePO4 NIMH Battery Capacity Tester Voltage Detector Analyzer. $11.58 shipped - not half bad for a semiconductor based unit!
As usual, I'm going to dive into translating the manual, then do some analysis on it.
