Turnigy Accucel 6 Calibration

[user119_]

Hi all,

I have Turnigy Accucel 6 charger that does not have a calibration mode. My multimeter suggests that it is off by 0.7v, which is very concerning.

Is there a way to calibrate it by changing anything on the circuit board?

I really want this to be as accurate as possible to check capacity of li ion and lipo batteries.

TIA.
