Battery Tester Electronic Load 0.1-40A Large Current Lithium Battery Charge Discharge Capacity Tester, Time/Cut-Off Current/Manual Charge Discharge Termination

I used this battery tester to test a couple of LiFePo4 batteries for an upcoming project and it did the job very well. I have to admit, I used it with the PC-Software and did not try to start a test serie only via the device, because this was a bit misleading. Controlled via the downloadable PC software and a Windows 10 Laptop it did a decent job by charging and discharging batteries with a constant 2A load or charge current. Even if a test serie could take quite some time (more than 16-20hrs in my case) it never failed.

Great product, but a bit tricky to find operating instructions in English (on-line only; manual furnished with unit is Chinese only). USB cable furnished with unit works fine once you download & install EB Tester software (a bit tricky to find, but easy to use once you get it installed and running). Current wires a bit light gauge for higher loads. Warranty registration card is Chinese only, so hope you don't need to use it! Power plug adapter fits sloppy / loose in US standard sockets ... spread the tips a bit to ensure good contact.

Power cable for the US 110V wall outlet was not included in the package.

Bad software. Preconfigured routines don't work like they should. Ended up writing my own. But the hardware seems to work.
