Just got my new BC6 and a new Evo 6s 2500 for my Trex 500.
I keep getting this error. Before you ask, my solder connections are excellent.
Am I doing something wrong ??

Take a DVM and check each cell. If each cell is OK, maybe a bad EAC129 board. When you get to the point before the cell count error, press the INC key and look at the individual cell voltages. Not if any are below 3.0V per cell.

When I press the INC key the first 2 cells show "0".
Checking with the DVM to the Deans on the battery shows 22.7.
How do I manually check the cell voltages with the DVM?

Probe each pin on the balance tap. Also make sure that you have the battery balance tap correctly plugged into the balance connection board.

Forgive me, but I'm an accountant not a EE.
I see 8 wires on the balance tap.
1. Black
2. Black
3-8 Red
I don't want to see sparks. What is the sequence 1-3, 1-4, ??

Put the POS probe on the pos pin, then the neg on pin 2. Voltage should be 1 cell, say 3.7V. Leave probe on pin 1, then move the neg to pin 3, should read 2 cells, say 7.4. ect..

8-7 = 3.7
8-6 = 7.4
8-5 = 0
8-4 = 0
8-3 = 0
8-2 = 0

You need to pinout the 2nd wiring set itself.

Took it to a client of mine, the EAC129 was BAD. The foam backing had pulled the super paper thin copper off the board. He re soldered the board for me and now it works great.
