Hi Stegy,
No, Futaba can only recommend using the 8 cells that the transmitter was made for in the 3PK.
I hope you find this information helpful. You can also reach our Futaba support technical team at 217-398-8970, or via fax at 217-398-7721.
Sincerely,

Hy,
I have been wondering, can I use 9 battery pack (AA's, GP2500) in my 3PK? I would like to extend battery life on my transmitter, especially for all day racing.
But I'm worried to test 9 cell pack in it.
Please advise.
