Guys,
I am facing a wierd problem on my Tahmazo T15 charger.
The charger is charging the packs fine, but as soon as I plug in the balancing tab of my 2200mah 3Cell battery I get an Over voltage alert. The display reads : 4.18 , 4.18 , 4.40

Now the cells are not really that out of balance. I checked with a voltmeter and they are all at 4.15 ( total : 12.50 )

I checked eveyrthing i could think of and conclude that somehow the charger is not calcualting the voltage properly.
Wondering if anyone else has come across such a problem ?  Looks like the calibration has gone wrong ?

Any inputs would be welcome !
