2500mAh Dualsky Transmitter Pack for JR Specktrum With Built in Balancer

Exapmle of Installation.

Jr 10X Installation, USE AT YOUR OUWN RISK The following describes how I installed the Dualsky 2500 mah Lithium battery into my 10X Transmitter. NOTE: This process may void your 10X warranty, check your paperwork or contact Horizon Hobbies to find out. If you choose to try and duplicate the actions described below you do so at your own risk and indemnify the author of any liability, loss of property or personal injury that may occur from doing so. The author is describing how he performed the installation but does not advise that anyone else do so. The 10X battery is enclosed in a case that slips into the back of the transmitter, on the front of the case is a six pin adapter that mates with pins on the radio. These pins feed the battery current to the radio, therefore, when replacing the battery in the 10X it is a necessity to use the case. This means it's necessary to open the case and replace the battery inside the case. The case is held together with four screws. I was able to easily remove these screws and open the case. Inside the case is an eight cell double A NiCad pack with two wire leads soldered to a small circuit board. When replacing the battery with a standard NiCad or NiMH pack all that needs to be done is clip the wires going to the circuit board (I left the wire coming from the circuit board as long as possible for re-attachment), remove the old pack, solder the leads from the new pack to the wire on the circuit board (using heat shrink to keep the wires from shorting), then put the new pack in the case and screw the lid back on. The problem with the Dualsky Transmitter pack is that the battery will not fit in the case. Therefore, what I did is cut a large rectangular hole in the top of the battery case to allow the cell to fit. Granted this seemed pretty extreme, but it worked just fine. I then followed the same procedure as I would with a standard NiCad replacement. Since the Dualsky comes with a Futaba plug it's necessary to cut each wire prior to soldering to the circuit board. When soldering batteries I always cut one lead only, strip, solder, heat shrink, then cut the next lead. This avoids shorting the battery. The Dualsky battery is not as long as a standard NiCad pack so to fill the extra space and keep the battery from moving around I inserted some foam in the open space. I then replaced the top of the battery case (which contains a huge hole) and then used electrical tape to tape the battery securely in place so it won't move around.
