6) YOU MUST not over discharge the Li-Poly battery pack
7) READ & UNDERSTAND the instructions carefully before operating this battery

NOTE: When using high energy Li-Polymer Batteries, please do not over-discharge or over-charge batteries as this will result in over heated batteries. Discharging capacity can't exceed 80% of the max capacity of the pack after full charging to ensure a good cycle performance. It is recommended to fully charge a brand new battery before using and only discharge the battery 50% for first 5 cycles. Always monitor race time and/or set a low voltage warning on ESC (End voltage cannot be lower than 3.2v per cell) Do not use the battery that has too low a voltage.

Do not expose batteries to sunshine or store/charge batteries at the temperature above 35°C or in a closed car. The high temperature environment could cause damage to the pack or make it burst. If the battery becomes hot while fast charging, high current discharging or racing, do not charge the battery until it has cooled completely. Wait about 20 mins, then inspect prior to recharging.

EcoPower "Electron" 4S LiPo 20C Battery Pack (14.8V/2000mAh) (Starter Box)
This battery has been perfect for me. No issues at all with this battery. For the price you can’t beat it. I saw some other reviews and I’ve had expensive brand name packs swell up after a single run. Maybe they got a bad batch. Mine is perfect and have been using for several race days. I keep it on storage if not a little bit more.

EcoPower "Electron" 4S LiPo 20C Battery Pack (14.8V/2000mAh) (Starter Box)
Used this a handful of times. Started to puff very early. Used it today and it gave me a hard time. Discovered one cell died and it's only got 3 active cells.

Disappointed and waste of money. Seems like bad workmanship is out there. Had a protek receiver pack that was new with a dead cell too. It's replacement has been fine so far and trouble free.
