The test sampling data are directly sampled from the outgoing terminal of the battery in order to really recover the battery working condition in the battery working process and make the test result more accurate. 4-wires internal resistance test, 4 digits display for clear reading.

The shell of DY226 is made of solid ABS engineering materials, and the load heating simulation part is up and down installed with stainless steel porous plate, and the fan is configured to strengthen heat dissipation in order to make the test process more stable and more reliable. The test line part is composed of thick pure copper test wire, and is also configured with four-wire Kelvin test clamp for connection.
