Hi,
A club member has just started to use a 10XP.
At first it worked as you might expect. - Charging 10s lipo - 5 to 10 amps.
Then for no apparent reason it would stop at 40 volts. - 4v / cell.
As it approached this voltage it would ramp down the amps then stop saying ; 'done'.
It did not switch to balance charging though. The only parameter to change was the charge amps - this just started ramping down with no indication as to why.
We tried changing parameters , different presets ,optimization and even power supplies.
It was behaving like a 10S in winter mode.
It had done this once the first day we used it and then was ok again ??!

Any ideas ???
