I am using an Ant BMS 10s-24s 180A/450A with LCD system. I have it wired to 16 cells. I have 2 identical units. Each cell is 272AH. Both are software set to 16 cells.
One of the two systems is having trouble with cell 1 reading 0 volts. That in-turn has it saying the overall voltage of the pack is 49.2V. All the cells are brand new and read 3.27V. When I test the voltage on the PCB just below the connector (14 pin) it shows the correct voltage yet the BMS doesn’t see it. Each and every pin checked in the same mannor has the correct voltage. My thought was a bad BMS. I swapped them with my other system and the trouble stayed with the battery pack, in other words, both BMS’s did the same thing on that battery pack. Both when put on the other battery pack work properly.
Believing the trouble must be in my connector or the single cell, I replaced the cell 1 connector/wire in the housing which did not help. I swapped the number 1 and 2 cells just to see if the trouble moved, it did not.
Again, the voltage reading on the circuit board where the connector housing is soldered through reads correctly at 3.27V yet the BMS says it’s zero. I am able to get that reading with everything plugged in and running telling me that the BMS is indeed GETTING the 3.27V.
@erickh I saw your post with the same trouble from about a year ago. Were you able to solve the problem?
I appreciate any suggestions and help. Thank you.
