Lithium Battery Charge Discharge Testing and Balance Maintenance Machine DT50W-17 
is capable of conducting capacity tests, charge and discharge characteristic tests, capacity grading and matching, balance maintenance, internal resistance tests, data analysis & comparison, etc., for a variety of Lithium batteries, Ni-MH batteries, and Ni-CD batteries. It offers physical compatibility with 18650, 26650, 32650 cells as well as pouch and prismatic cells. With its isolation measurement design, the DT50W can balance charge & discharge individual cells within a battery pack to ensure uniformity while identifying any faulty cells without requiring disassembly and restore unbalanced battery packs to their normal balanced state through balancing charge-discharge operations.

The device features a modular design, enabling parallel testing with a maximum current capacity of 170A.

The device is widely utilized in battery production facilities, battery recycling plants, research laboratories focusing on batteries development or new energy vehicle batteries testing and maintenance.


DT50W-136 is a 136-channel testing cabinet consists of eight single machines to meet the needs of mass testing. Multiple testing cabinets can be connected through a network switch to form a testing machine group to meet the needs of large-scale battery aging and capacity classification.
