It happens now and again.
I stay away from e-bay $9.99 humps.
Get a good one from your LHS and you should be fine.
If you need one for this weekend I have a triangle configuration (3-2) you can have.
LMK
Not sure, don't have a Savage
Its 3 batteries wide with 20 on top.
Ill find a link.

Like this one.
Ill find it and put a charge to it tonight to make sure its good. http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXVG17&P=ML
Its on the charger now. Looks like it should be fine.
I had a deans plug on it so I soldered a new cord on it so it will work in your Savage.
I hope its long enough. Is your RX in the same compartment as your battery?
