I checked my packs by cycling them and noting MAH for a discharge and for a charge. All of the packs were way below specs. They did not hold what they were supposed to. Trying drain them at any substancial rate pulled them below 2V/cell. They were marked 2011 manufacture date. They were the Olevin Hobby King version. Since mine were gently used an stored in favorable condtions, it might be worth analyzing any packs or cells you all have out here before you fly them.
I ordered a bunch of brand new A123 cells. There is only one authorized dealer in the USA for GENUINE cells. They also drop the price in half if you order several cells. I'll make up news packs.
I use the 3rd wire on a Futaba type plug for a tap between the cells. That makes it possible to balance the packs in the airplane using the charge port. So, I need to make my own packs. Pretty good deal for $20 a pack.
