I left my Turnigy 9X transmitter on and my LiFe battery drained to death. It became bloated, swollen, and now won't take a charge. It looks like it's about to explode. I had to temporarily rig my T9X to take 8 AA batteries so I can fly in the meantime. The guys at www.parkeflyer.com pointed out there's a Zippy battery that will fit the 9X available at HobbyKing's USA warehouse:
That means no expensive shipping and long wait times.
Please, please take caution using LiFe and LiPo batteries. I always thought it wouldn't happen to me, but it finally did. Thankfully nothing major happened, but I've seen some YouTube vids of these things lighting up pretty violently.
If you're interested in an ammo box please send me a PM and I'll put you in touch with my buddy that has several of these.
