GreatPlanes ElectriFly 1200 lipo 3s ICE Discharge Graph.

This the anatomy of a pack that failed early in its life, after only 6 flights the power started to sag and the LVC would constantly trip early.
Not sure why it failed, but I've learned a lot about battery care since this pack was purchased.

It was used with an E-Flite Park 370 - 4200 motor with 6.6/1 gearing and an APC 11x4.7 SF prop.

I noticed the front bearing on the motor was getting a little noisy a few flights after the battery failed, that may have been a contributing factor? The pack had good power up to the failure. The flight before the failure had a very low resting voltage of around 9.6v even though a 3v per cell cutoff was used.

The last graph is a 100mA voltage charge graph of this pack.
