Dear,

please advice me.
Balancing not working. 
Used Steval board with J13, J14 and all J5 open (disconnected) .

HS mode.
3 cells connected (C5-C4-C3) and (C2-C1-C0-GND)

Used test script:

WRITE 6 0AD8 N=10, Cell OV = 4.21632V
WRITE 7 0A33 N=10, Cell UV = 0,99552V
WRITE 8 0A0A Severe Cell UV = 0,8V, Severe Cell OV = 4.41152V
WRITE A 0AE2 N=10, VB_OV = 22,0576V
WRITE B 0A2D N=10, VB_UV = 4,392V
WRITE C 16 VB Sum Max Diff = 1,0736V (0B) 1,464V (0F) 2,14 (16)
WRITE D A000 N=10, NTC OT = 0V
WRITE E AFFF N=10, NTC UT = 3.30057V
WRITE F 1 NTC Severe OT = 3.30057V
WRITE 10 FAFA test má byt 0x13 pro 2,2 A ( 1313)
WRITE 11 00FA test persistent OVC TH 2,2 A
WRITE 9 0A05 bal_delta
WRITE 1 007C CHR DCHR Balancer
WRITE 4 1AFC Enable 3 cells, VB, & NTC measurement proud
PAUSE   Press OK to begin voltage acqusition  
WRITE 2 07FF Start acquisition. Filter times set to max - Tmeas_cycle = 150ms


Everything seems to work fine but balancing not
What am I doing wrong?
Will balancing affect charging or discharging or both?

Thaks you very much

Pavel
