Aleph 19 cree XR-E and rechargables?

[ironeagle0074]

I just bought the above head with a GD825 driver off the for sale board and was wondering if it was possible to use a rechargable 123 with it?

If so, what are some brand name and charger selections?

This is for use in a 1x123 body.

Thanks
Brian

Yes, it's able to use rechargables. I just bought the same head a couple of hours ago! It'll run off of CR123, RCR123, or any 3.7v Li-ion rechargeable battery.

If you're going to use a single RCR123, a Nano charger (very inexpensive) will suit you very well. You can get a protected RCR123 from AW. He'll probably have the Nano charger, too. Lighthound also carries AW's batteries, and likely, the Nano charger, too.

What's the difference between RCR123 and 3.7v Li-ion?

They are one in the same heres a breakdown
Lithium:
CR123 = Primary Cell 3volts

Lithium-Ion:
R123, RCR123 = Secondary Cell
3.6v protected (for use in series, parrallel, or single)
3.7v unprotected (only use single)
Also 3.0v Rechargeable called R123 3V

Most rechargeable Lithium-Ion cells start off at 4.2 volts fresh off the charger.
Unlike NiMH AA or others which come off the charger at ~1.25v
Search for Battery University's guide on all things rechargeable its a good lesson.

An RCR123 is a 3.7v Li-ion. What I was meaning was that it will work with other 3.7v Li-ions, such as a 17670, 17500, or whatever size battery your tube will fit, which means you can buy other, longer battery tubes for your A19 Cree and get more run time (or less, if you can find a smaller 1XRCR2 tube).

This thread should help you out if your just getting started

17500 = A (surprise they exist)
14500 = AA
CR123 = 16340
2 X CR123 = 17670
CR2 = 15266
2 X CR2 = 17500

FWIW, here's my runtime tests on the GD825, using a single R123, and then using a 17670 battery on a 2x123 tube.

Will a 3.7v battery push the light harder or make it brighter?

It should work the same.

I run an A19 XR-E driven by a flupic powered by a 17670.

I cannot think of a better setup! the low is LOW, and IIRC, the burst setting drives <1.2A
