A 10S pack is capable of charging to 43.5 volts. The rules say the legal limit is 42.99 volts. Capacity increases on the 5100 10S in the neighborhood of 500 mAh with the added volt. That's consistent and quantifiable on my Power Lab chargers. So the added capacity is significant.

At the Nats HV pack users were identified and voltage checked before each flight. Non HV pack users no check needed. The ID process was to look at the label on the packs. So I have labels for our packs that say they are HV. I also have labels laying around that don't say HV. Albeit they say Gator Power packs instead of Power Unlimited HV.
