This lightweight Li-Poly 30C battery pack is designed to fit radio controlled cars, planes and helicopters that require a 5S 4500mAh battery pack, such as the T-Rex 600 when running on 10S batteries. These batteries are a true 30C battery pack, and with a full 30C discharge capacity and light weight, these batteries are a power house for compatible cars, helicopters and airplanes!

Unlike most other Lithium Polymer batteries, these batteries can be charged at up to 2 times the rated current, or 2C! If your charger is capable, you can charge these batteries at up 9A!

1) You will need a Li-Poly specific charger to charge the pack (NiMH or NiCD only chargers WILL NOT WORK!)
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.
