Oh right, I thought voltage was measured along the balance leads.

One more quick thing, I just used my Hyperion charger to charge the lipo, and it charged it up to 4.19v. I then hooked it up to the included Celectra charger and it charged for a further 10 minutes. I reconnected the lipo to the Hyperion and it now read 4.23v. Is there any way to make the Hyperion charger squeeze more juice into the lipo?
