Default Make your own JR TX pack.

The one you can buy from JR is 700mah Ni-Cd your new one will be 2400mah Ni-MH.

well I had a pack with a bad cell in it. So I made me a new improved pack.


supplys needed.





cut shrink wrap to length.



Heat it up, fan the blow dryer dont sit on one spot to long.



Charge it, and love the new longer runtimes and longer battery life. Ni-cd 700mah converted to 2400MAH NiMH.

Aren't packs supposed to be glued together, soldered tagged then shrink wrapped, and not in a battery cage & shrinkwrapped?[:-]

NOt in a JR. No plug needed inside JR's battery tray.

uses 2 connectors almost like whats on a 9 volt alkaline.

Funny thing is you can use the factory AA tray with JR.

In the 4-10 channel JR radios the tx battery is soldered and shrink wrapped with a connector for superior performance. the lower line of JR use the battery holders. IT is NOT wise to use the battery holder in case of loss of battery failure(i have seen it happen). It is a common problem with these type of battery holders. You are better off to solder the individual cells together then glue the pack up in the same way adding a connector for optimum performance. Making a solid pack is the safest way to maintain a rc car.

Funny when I took the JR pack apart that failed on me it used the same battery holder that you would use for AA's. There is no differance here. THe shrink wrap holds the batterys in place they can not fall out.

For my XS3 I purchased 24 AA 2400mah batteries and it works out great. I label them set 1 & 2 and rotate sets, I use a 9 volt plug to charge them.
