    Hi can you post a video or schematics on how to build the cable that connects the board to the BR3000?

      Hi cook71, we just carried pin 1 to pin 1 and so on to another cable. We soldered our extension cable to the back of the board from the nearest XH header since there’s more room than on a TP/FP connector. I’b be a little hesitant to recommend it since it’s pretty easy to short leads between pins and that would be catastrophic when you plugged in a balancing lead. Proceed at your own risk! If you do make your own, triple check the connection, verify polarity, and use a continuity checker to make sure nothing shorted.

    Hello Friends. When I do the calibration of tp820cd As you explain in the video. Calibrate each cell for .1mv and then turn off the charger at the end. When I turn back I’ll calibration manual check and I get the same values ​​of 2 digits not 3. I’m doing wrong? Or tp820cd not show the 3 digit voltage only does tp430c? Please you appreciate their help. Thank you.
