No matter what kind of transmitter you have, SR makes a pack for it! Not only that, but even though your transmitter might have come with a 500mah pack, we can make a 800mah or even 1500mah for just about any transmitter ever made that's exactly the same size as the original pack! 

Here are some of the things that make an SR transmitter pack different:

• All SR cells are screened and matched Aerospace Grade cells. These are not your usual consumer type inexpensive cells. They are exactly the same cells we use for our military/aerospace applications.
  

• Only SR guarantees its cells and packs not to ever form a memory and warranties each pack for one year.
  
  
• Only SR puts every pack through five days of electronic testing to make sure every pack is perfect. These tests include a test of capacity, charge retention, and a vibration test for mechanical integrity.
  
  
• All welded internal and external construction. Would you believe that some companies sell cells where the internal connections are nothing more than a press fit? We don't even have soldered connections, except for the connector leads themselves.
  
  
• Even the straps we weld from one cell to another are an SR exclusive. Our straps have an exclusive strain relieved section so that no vibration or stress is transmitted to the welds at the end of each cell. No one else has this feature!
  
  
• All SR packs can be fast charged. Of course no cell will stand up to extreme overcharging but all SR cells have the lowest possible internal impedance so that fast charging isn't a problem.
  

You'll find all of our transmitter packs listed below by their shape and the particular applications they are used in. If you'd like a printed copy, just hit your browser's "Print" command.

Special shapes or wiring requirements are never a problem. We'll be glad to add any "custom" features you might like. Just indicate these requests on the special instructions section of the order form, or give us a call.
