battery volts

Yes, thats fine- nimh cells carry a fairly high peak voltage around ~1.4v per cell, so a freshly charged pack will read alot higher than its nominal rating of 8.4v (1.2v per cell), though it will drop off fairly quickly back down to nominal or there abouts, so let it cool down off the charger and use it fairly soon after to get the most benefit.
