I bought a Tanic 2100 mah 11.1 volt LiPo battery pack for my Crazy 8. I only charge the thing for about 20-30 minutes and have short flights (don't really care until I get a Poly Charge 4 and another battery). I just started thinking about that when the battery 1: sometimes the battery charger (Electrify Triton) announced it was charged after, at the most, 5 seconds of charging, and 2: after the 20 minutes the motor could go at full power for all of 20 seconds. Anybody have any ideas?
