2) You must not over discharge the Li-Poly battery pack.
3) Read 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.

I Bought two of these for my RC8BEm they fit perfect! I had one go bad on the first run I used it, just straight up died on me. Called A-Main and got a new one shipped out no questions asked! I dont blame A-Main or Protek, it was obviously a defective pack which happens. They run great and have a ton of punch! The nitro guys could not believe I was going for 20+ mins and still had the power I did. Buy'em!

They have redesigned these packs since the other reviews and the new shorter length fits in the rc8e just fine.
