Tx Battery

       Remove this ad - become a site supporter!
Hey all,
Anyone know a Canadian supplier where I can get a high capacity (1500mah+) Tx (JR9303) battery pack?

I check all the RCC advertisers and no one seems to have them in stock.

Re: Tx Battery

Parker Model is a distributor that sells them.
He can tell you which shop has them.
He's local to me if you need someone to pick it up.

I believe he sells LIPO tx packs for JR.

Re: Tx Battery


What I did was to solder 8 - 2700mah NiMh batteries together, then use heat shrink to hold them together (one layer of electrical tape would probably work just as well) and use the connector off my old battery pack. I got the batteries from Factory Direct, but I also see them at camera stores, Zellers, CTC etc.

Since the Tx does not have a heavy load like the receiver, they work fine and last a long time. I charge them out of the Tx for a faster charge with my NiMh charger. Fully charging with the wall wart takes too long.

Hope this helps.

Re: Tx Battery

Before you go the Lipo route see the warning below from the JR website;

Heads Up, Use the right batteries in your JR transmitter for best results
Monday, March 17, 2008

Warning concerning use of non-standard transmitter batteries

JR transmitters are designed to be operated on 9.6 volt Ni-cad or NiMh batteries only. Use of Li-Po or other power devices operating at higher voltage can add heat to the system, possibly overloading the power regulating transistor for reduced output. Despite what aftermarket battery manufacturers might suggest, use of non-standard batteries offers decreased reliability of your JR radio. Our service department has received failures associated with Li-Po packs.
