Yes.

Jon boy, welcome to the gang. By the way, I'm using a single 17650 in my dual mode Fury; works fine...

You can use a 17670 as well. At least it fits in mine.:welcome:

What's the difference between 17650 & 17670? Capacity?

I'm thinking it's more a labeling difference between manufacturers, or more specifically the length distinction between an unprotected and a protected cell?

Welcome to the Forum! :welcome:

You could also use a 16650 cell. It has a little more mAh's in the tank. AND it is from a good base cell (Sanyo).

What's the advantage of using a 17650 over 2 LiFePo4's (3.0v)? Will it be brighter on high or run longer? This would be for the G2X Pro

Labrador72 · Mar 14, 2014

Longer runtime. Note that I have seen some G2X users saying they could not fit 17670 batteries.

Goodnight Jon boy.

I tried a couple rechargeable lifepo4 batteries in my 350 lumen light and they were only discharging 0.5 amps. On primaries the current was over 1 amp. These batteries are limited I assume

Was it still putting out the same amount of light? lifepo4's power my UB3T (800 lumens) at max power no problem. Realize that lifepo4 cells have slightly higher voltage than primaries so when you test the current it will be less because the voltage is higher. However, as the voltage sags the current will rise. Voltage sags much faster on primaries than lifepo4's.

Someone will correct me if I'm wrong on this.

My AW 17670s when stacked next to a pair of Energizer primaries, measure nearly exactly the same. So close I cannot see the difference.
