AW Protected 17670 batteries in an RC-F4?

[CathastrophiX]

Does anyone know if the AW protected 17670 fits in the Romicen RC-F4?
Or can someone please measure the diameter of the battery?

AFAIK no 17670 will fit in the RF-F4 unless you widen the inner diameter.

Just take a big drill, some sanding paper, tape the sanding paper onto the drill and then you need some time (~20 min).
I used an cordless screwdriver for doing this.

You should remove the head + pill before doing this of course.

Actually, I think some will, especially unprotected. I could have sworn on DX there was a link back to a post here talking about it, about extended run time and better efficiency.

Also, BessieBenny's thread talks about using them, at least non-protected.

He mentions sku 2844.

Ultrafire 17670 unprotected (blue) fits, but it's fairly tight.
