Ok I have had this charger go about 2 years barely been used i mostly use my hitec x2 charger I took it to the track and noticed all my batteries on cell 1 are about .10 higher than cell 2 on all 5 of my batteries. And on my x2 they are all fairly close. I tried different balance boards and no luck. Is there a possibility that it came un-calibrated? Is there anyway I calibrate? There is nothing in the manual and I can't find anything online. Charger is still in perfect shape I would hate to junk it
