What'd I miss here? I have a pair of Aplus 11.1v 2200mah batteries (came with the hurri550). Put each on the KP-100W6, and there were some minor variances in the cells (one batt had a total var of about 5mv, the other was a LOT worse @ 125mv) Set the first to charge, then balance, and all came up OK. Did the same with the second, and it finished with a 50mv variance across the cells. I didn't think this would be a HUGE deal. Or was it?
I don't do ANY 3d yet, and so put them in the Hurri, and spun it up to check tracking, cyclic, gyro etc. Only got up into a hover for about 15s, and maybe spent about 3mins at 1/2 throttle. I didn't use a timer, as I wasn't "actually flying" and everything seemed OK. When I got back to the bench to pull the batts out, #1 seemed just fine, but #2 was somewhat swollen. Put #1 on the charger, it only showed a very minor variance, and so I put 1100mah back in. Pack 2 is now showing as a 2cell pack? WTF?? This was the first use/charge/cycle. Did I kill the pack??
I have the logs from the charge/balance if anyone's interested in taking a deeper look. I'm just not sure what to do. Do I contact Fung or Aplus? Do I rack this up to noob stupidity, and buy a new battery? I've got 2x http://www.bphobbies.com/view.asp?id=B1018380&pid=C1436802 on the way to hopefully lessen the change of this happening agian, and I normally time my flights (on the CP2).
I also have a pair of Kongs @ 2200mah too, but before I go out and destroy them, I'd like to make sure I know where I went wrong!
