bought a few A123's a couple of months ago. Put 3s in an electric old-timer (buzzard bombshell), used to fly on 12 NMHs, had to drastically lighthen the tail-end. flew great!
then tried 3s in a combat wing, great duration. Now have a 4s in a Sebart Katana. Due to mounting the wrong Hacker gearbox ,I was pulling 60A,(great verticals!) that fried the 80A Hyperion controller after a few flights, but the A123's were just warm, no problems. As my lipos age, they'll get replaced by A123's.
Charging them at 6A, may try some at 8A.(with temperature sensor attached!) I am using a Hyperion LBA10 charge balancer and a Schulze Lipodimatic in-flight cell monitor set to 2.5V per cell.
My schulze charger cuts-off at 3.65V/cell
