LiitoKala Lii-M4S Multifunctional Battery Charger/Tester

LiitoKala Lii-M4S 18650 LCD Multifunctional Battery Charger and Tester For 3.7V 1.2V 26650 21700 14500 18350 17500 AA AAA A C and other cells. It has 4 individual slots and possibility to charge different type of cells/batteries at same time. Got this to test out my old Eskate 18650 cells as it can charge, discharge, test and put cell in storage voltage. Amazing all in one device to say no more. I was able to test all 50 cells where I was able to sort cells out by available capacity and identify 5 dead cells. Testing 4 cells at a time takes around 8 hours to charge – discharge and charge again. Device gets very hot while discharging cells (4 cells max at 500MA at a time). In case of need device also can be used as a powerbank. As it did everything I needed and survived my multy-day stress test I will recommend this device as it will be very handy also in the future.
