I bought 4 of these a year ago using balanced charging and running them in my Slash 4x4 on LiPo mode all 4 inflated and won't charge after 4-5 uses.
Works ok, might have some kind of "underswing" that triggers the low voltage safety function in the speed control when driving a little harder.
This may be an isolated experience, however, with balanced charging and running with the Traxxas Rustler VXL in lipo mode with voltage protection. This battery failed and would not accept a charge after 5 runs. Not good.
Had to purchase and install the bigger battery hold down kit from Traxxas to use it. But battery works great!
