All charged with hyperion 610i charger, and placed in store mode when I did not use them. All less than 1 yr old if memory serves me correctly. No puffing or issues. All have deans on them (real deans, not immitations).
Neu 3s 5000 25c. Great pack for a pede or rustler. Never got past ambient, maybe 12 runs on it. Slight scuffing on the shrink.
(2) Flightpower 2170 25c 3s packs. Used in my tamiya m03 fwd car. They have 12 or so cycles each. Some velcro glue residue on one pack.
Flightpower 6400 30c 5s pack. This was a bench test pack for BVM edf jets. 3 cycles total.
