The easiest thing to do is purchase the newer 1100mAH transmitter pack which ships with the 9Z WC2.

Get the battery for the 9z at radicalrc dot com and you'll save a bit of money. Beware though that radical may not know how to bypass the diode correctly. He did mine incorrectly, and I had to redo it the right way.

Please don't jump the 9Z battery within the case. The unit is in place in the case for several reasons.

Instead you can simply jump the diode when charging with a simple discharge jumper. You can make your own or buy one:

HSP78050 9Z DISCHARGE CONNECTOR 1 5.00 retail

You can ask your favorite hobby shop to special order these parts for you, which may provide you some savings from full retail pricing. Alternatively, you can purchase replacement parts directly from us, by simply providing us your mailing address and the stock # of the item you require, as well as a method of payment. You can fax or mail us with a credit card # or mail a check, or we can send COD for an additional $5.00 fee on top of the standard $3.00 shipping within US or $13.00 shipping outside US.

May I ask, what are the reasons that the unit is in place? And, under what conditions may the jumper be used? From what you say, it seems to be implied that you would use the jumper sometimes (while charging?) but not others (while the radio is on?).

Does this mean that you must charge the battery outside of the radio?

I know I'm jumping to conclusions...hehe....Just trying to think it out.

Thanks

You need to bypass the diode to discharge (cycle) the pack, otherwise leave it in line as I beleive (and I have been known to be wrong on occasion ) it is there to protect the electronics from any sort of power surges or overloading, so without the diode then you could potentially damage some expensive components.

The jumper is used outside the radio solely for discharging.

The diode is in place to protect against power surges, lightning strikes, accidental reverse polarity (plug your leads in wrong on your charger or use your JR charger by accident), etc.

I had my local Batteries Plus make me some new 1100 MAH packs, and they only ran me 15.00 each!! I used them all last year with no problems. All I had to do was remove the screws on the plastic case, and solder the two wires on. Really easy, and man do they last longer than my old 600mah packs.
