5V 20A Li-Ion Cell Capacity Grading And Matching Charge Discharge Tester
Li-Ion Cell Capacity Grading And Matching Charge Discharge Tester DT2020 5V/20A can be applicable for capacity test, auto-cycle charge and discharge test, capacity grading and matching, balance maintenance, internal resistance test, etc. of various Lithium Batteries, Ni-MH Batteries, Ni-Cd Batteries. It can be compatible with 18650, 26650, 36650, pouch, and block cells. Maximum charge-discharge current 20A, suitable for testing the large capacity cells. DT2020 isolation detection technology can determine the location of the bad cells without disassembling the battery pack, then replace it. It can balance charge and discharge the unbalanced battery pack to balance the battery and restore the battery pack to normal balance.
It’s suitable for lithium battery performance testing, maintenance, regeneration, pack assembling, and EV battery rebuilding, etc.
The testing cabinet DT2020-64 is composed of the single DT2020, a number of DT2020-64 can constitute a testing group to match the needs of mass testing.
