Does anyone know the voltage and capacity of the B90?
Is there anything I can use in place of it?
Thanks for ANY help.

I measured 4.2V for a fully charged B90.
I wonder if an 18650 would work it i make the ground connection along with a spacer.
maybe an IMR18650?:shrug:
I made my own B90 sticks with NIMH cells eons ago and then I bought one from Silverfox's last run and it is still working great but I would like to avoid the constant maintenance involved with NIMH cells. I previously asked Silverfox if I could put two protected AW 18650's one on top of the other and wire them in parallel and he told me that not only would it work but that it would yield a higher MAH than either NICAD or NIMH cells. But unfortunately I could never solve the top portion and still have it wired in parallel and still fit in my 8AX. I think that if I had a spot welder it would be easier to build. So, your idea with a spacer will work but it seems like a lot of wasted space.
When I get more motivation, I will try to wire 2 X 18650's in parallel and see what happens. I have an 8X that I just got and have a Turbohead on the way for a 9AN that has never had a head. I still need a 9AN tailcap though. Id like to use these lights but really have heard nothing but bad things about the B90. If I get it done, I'll share my results.
Thanks again to all the great member for your help!
