Surefire B90 Nicad

What voltage does this battery run at?

Is the B90 length compatible with any common Li-ion combined sizes?


Thanks :wave:

my guess is 2x 17670 size, 4 2/3cells, 4.8v

NVM some site had it spec'd at 3.6v 1500mah. it's probably 3 cells maybe 4/5a or SC cells, both about 1.75 in length but the SC come closer to the .9 diameter.
I found the specs on apexbattery.com and used cheap battery packs.com as a reference.:shrug:

A B90 is three Sub-C sized NiCad cells, last ones were 3.6V at 1800MAH...

Ok..


The reason that I'm asking is because I'm wondering if there are any alternative power/bulb combinations for the 9AN, 8AX, and 8NX. I know the 9AN would be very difficult because of the to bulb arrangement but how about the others? Anyone ever run them with a combination other than the B90?

Thanks

Eh, I can't see much conceivable gain by swapping the bulb. 3.6 is pretty low voltage, maybe a single cell e-series lamp or replacement lamp, but I'm pretty sure you'd be loosing output (assuming that's what you're going for) That's if the lamps will fit. I'm not sure what a B90 powered lamp looks like, I'm guessing it's bi-pin. Maybe check WA or Carley for lower powered lamps.:shrug:

Silverfox made a limited run of B90 replacement packs using specially selected GP Sub-C 3700mAh cells. With incan, this gives nearly twice the runtime and slightly brighter output. The L7 gets almost exactly twice the (high level) output.

This is what I did with my Silverfox packs.

Wow. Nice L7. Sounds like the GP Sub-Cs are the way to go.
