Pulse Spektrum Transmitter Pack - Incredible Run Time at Half the Cost

Replacing your NiMh transmitter battery with a dedicated transmitter lipo battery brings a new dimension to transmitter functionality. Gone are the days of the constant need to keep your Tx lipo battery charged or topped off, and never again will you have to worry about having your Tx lipo battery die at the field.

Utilizing a 4000mah 2S 7.4V LiPo battery dedicated for the Spektrum DX7S & DX8, this battery will provide immense flight time with your transmitter, allowing you to simply enjoy flying. Further, at half the cost of the stock Spektrum LiPo battery, the Pulse Ultra Tx battery allows you to enjoy all the benefits of LiPo battery technology without the excessive cost.

Designed to charge inside your transmitter with your Spektrum based transmitter charger (not included), the charging process is simple as it gets. Simply charge your Tx battery as normal, and get ready to enjoy massive run time without the worry of a dying transmitter pack.

Note: For Spektrum DX7S, DX8 & DX9 users, be sure to select the "LiPo" function within your transmitter when installing the Pulse Ultra LiPo battery. This will allow your transmitter to properly monitor the battery voltage and warn you when the battery voltage becomes too low.

This LiPo transmitter battery is intended to power a transmitter only, and is in no way designed for use as a flight power system, such as powering a motor / ESC system. Due to the lower discharge rate and lighter gauge wiring, any use as a flight pack will immediately void the warranty of this LiPo battery, and very well may cause battery failure.
