This is a ProTek R/C 2S – 7.4 Volt, 2800mAh Li-Poly transmitter battery pack. This battery has been developed specifically for the Airtronics MT-4, M11X, M12 and KoProPo EX RR transmitters. This light weight Li-Poly transmitter battery will help to reduce the overall weight of your transmitter, which is great for long main events! The overall weight will be significantly reduced when compared to a typical NiMH transmitter pack as this battery weighs a scant 105 grams! (Six typical NiMH AA batteries weigh approximately 168 grams). This battery will not only reduce the weight of your transmitter, you also get an incredible 9 to 10 hours of run time!

How should the battery be inserted into the transmitter?
A suitable foam should be used to pad the battery in the transmitter battery compartment to help hold the battery in place and prevent it from moving around. Place a piece similar in size to the battery into the transmitter battery housing under the battery, and then while pressing lightly on the battery, slide the cover over the battery.

Specifications:

  • Voltage: 7.4V
  • Capacity: 2800mah
  • Chemistry: Lithium Polymer
  • Balance Charge Plug: XH
  • Charge Rate: 1C
  • Discharge Plug: JR/Futaba
  • Dimension (LxWxH): 99.2x31x17.9mm
  • Weight: 105g

IMPORTANT:
1) DO NOT leave the battery in your model when charging
2) DO NOT leave unattended when charging
3) ALWAYS balance charge the battery
4) ALWAYS use a LiPo charging bag
5) YOU MUST use a Li-Poly specific charger to charge the pack (NiMH or NiCD only chargers WILL NOT WORK!)
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.
