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

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

Specifications:

Cell Count: 2S (7.4V)

Capacity: 4,000mah

Dimensions: 70mm x 51mm x 18mm  (LxWxH)

Weight: 135g

Charge Rate: 1C / Do Not Attempt Higher Charge Rates

  • Product Note: 
    • This transmitter battery is designed for 1C charge rate and a 6C discharge rate - do NOT exceed greater than 1C during the charging of this LiPo battery. Any charge rate greater than 1C / discharge rate greater than 6C will immediately void the warranty and very well may end up in pack destruction via fire. It is the end users responsibility to ensure proper safe charging practices, so please be aware of this.Also, please be SURE to charge this transmitter pack with a designated LiPo battery charger - do NOT attempt to charge this battery inside the transmitter via the stock transmitter charger - if done so, this battery WILL fail, and will have the potential of fire, resulting in serious harm to the transmitter and surrounding areas. Any attempt to charge this battery without a designated LiPo balance charger will immediately void the warranty in full, so please be aware.
    •  Warning: 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.

Pulse Ultra Batteries – Your Questions End Here.

Have a question regarding Pulse batteries? We have assembled a spread of questions that are commonly asked about Lithium Polymer batteries, along with Pulse batteries as well. Of course, if you don't find your answer here, feel free to drop us a line, as we are always happy to help.
 
Q: What is a "C" rating, and what does it mean to me?

A: "C" ratings are categorized in (2) areas – discharge rate, and charge rate. Pulse Batteries range from 15C, 25C, 35C, 45C, and 65C in discharge rates – this is based upon how much amperage can be delivered, or in simpler terms, how much power your battery has to give. The higher the "C" rating, the more power the battery can give out.

As for the charge rate (excluding receiver & transmitter battery applications), Pulse batteries are rated at 5C, which means they can be charged 5 times faster than a conventional 1C Lithium Polymer battery. In short, Pulse batteries can be charged at very high rates of power for rapid charge times, eliminating the wait time of conventional batteries that are limited to 1C.

Q: What is mah, or capacity, in terms of Pulse batteries?

A: "Mah" short for milliamp hours, is a reading of capacity, or how much energy the battery is able to store. Mah, or Capacity, directly relates to flight time, and indirectly relates to power output, as higher capacity batteries also have greater amperage to deliver, when asked to do so.

Q: How long does it take a Pulse battery to charge?

A: Considering Pulse batteries are rated at a 5C charge rate, if your charger can deliver the necessary amperage to charge at 5C, charge times can be as low as 15 minutes, depending upon the charger being used.

Q: How can I determine how many amps my Pulse battery can be charged at?

A: To determine how many amps you can safely charge a Pulse battery, a little math is in order. We will use a simple formula to determine charge rates - divide the "mah" of the battery by 1,000 (let's say a 2200mah battery), which comes to 2200 / 1,000 = 2.2. Now, multiply it against the "charge" rating of the battery, which in this case is 5C. So, in this case, we have 2.2 x 5 = 11.

So, if we have a 2200mah 5C battery (2200 divided by 1,000 = 2.2), we have 2.2 as our base number, which we then multiply against the charge rating of "5C" which gives us a number of 11 – (2.2 x 5 = 11). What this means is that at a 5C rating, a 2200mah Pulse battery is capable of being charged at 11.0A amps of power.
