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.
