TCPilot,
just to make things clear,
6P = a 2-cell, which will run the P60 and P61
6P + A19 body extender = a 9P, a 3-cell, which will run the P90 and P91.
6P + an A14 body extender = a 6R,
(Which is the rechargeable set-up, running the P61 for 12-18 minutes. Of course, you need a B65, [or two/three] plus the charging cradle and wall-transformer, etc. These are all available as a kit, "the KR2, 6P to rechargeable".)
If you have a
6P + A19 + an A20 = 6R
(A20 is another body extender ~1" long, which will make your 9P longer without needing the A14).
Once it's made up to a 6R, (the longest style) whichever way, there is a ###, "blank battery" thingie, which allows you to leave the body parts in place, but insert that "blank", and you can use it as a 2-cell without removing the body extenders.
(I forget the number for it, but it's not the Z20, which is just a blank 123 length. Will look it up ... )
[Edit - looked it up, and it's the *Z29*, "Converts 6R back to a 2-cell lithium without taking any body extensions off."]
Clear as mud ?
let me know,
