Hi Jason,
On the AMT batteries you can get 9.something volts in them. When they get down to the supposed voltage under load they are nearly flat.
The ultra duo charger is worth its weight in gold!

ECU Pack
 

Hi Jason. 7.5 is correct. I never run my 500/750 with less than 7.8 on the ECU Pack. I usually quick charge the pack between each flight. The pack is a 7.2 volt pack but you can get well over 8.0 in them. If you do end up quick charging the pack before each flight (which is what I would recommend) make sure you do a deep cycle of the pack every so often. Quick charging often lessens the capacity of the pack hence requiring a deep cycle to get the capacity back up. Good luck!
