A2 aviator on rechargables? voltage regulation or current regulation?

[Youfoundnemo]

I have a friends A2 for a week or so and Im really starting to get attached, i know that if I were to get one for myself though it would HAVE to be guilt free, does anyone know how the A2 feels about the liFePo4 batteries (or if there is a 9V bulb for running 2x IMR16340)

I tried the search and nothing came up

lovecpf


More questions: will running two 16340s push 7.4+ volts to the bulb? I guess what i would like to know is if the A2 regulates the voltage going to the bulb or if it regulates the current?

I have run an A2 on AWs older non-protected rechargeable 123As for years. The LEDs are a little over-driven but there have been no problems. Others have had the same experience. Look at the A2 appreciation thread.

Same here. I only use rechargeables in my A2 now. I've used the black protected AW li-ions and currently use AW red 16340 IMR cells. Go for it :thumbsup:

I'm using Tenergy 750 mAh RCR123A 3.0 volt Li-Ion batteries (yellow label) from Battery Junction.

No rechargeables will get you the same runtime as primaries, but AW's IMR 16340's are a good option right now.

Why LiMn? They're lower capacity, and I thought I'd heard some protected LiCo cells fit fine... :thinking:

EDIT: And AFAIK, the current shouldn't be an issue? I thought it was like 1.3A or something...

FM makes a Strion lamp holder.

It makes the A2 brighter for similar runtime and runs off a single rechargeable cell.

RCR123A and IMR's? I have the impression that 3v rechargeables are preferred because the 3.7v overdrives the LED ring.

Re: A2 aviator on rechargables?

I've tried a few different protected's in my A2s and none fit. I never did order any from AW though, it's possible his do.

That's why I'm interested in IMRs anyway.

I do love A2's but I may be switching my EDC soon so I'm not sure I'm going to invest in rechargeables for my wing.

Are yoy sure it will run off one cell? The regulator does not change. I'll have to try mine tonight and share the results.

Hello Dan,

I've spoken to Milky, since I know what LEDs are in, what voltage drop they have and what current they can handle.

Result of my calculations: even with VERY full rechargeables (total 8.4V) the LEDs won't be overdriven.

The incan should be no problem at all, as there's a VOLTAGE regulator in it (a PWM-type regulator). The bulb itself is 4V only, so when having 6V or more, the regulation will be fine. You won't blow anything with the 2X 3,7V rechargeables here.

Bottom line: just put them in, at my risk :green:

It works, (AW IMR16340s) it really didnt like the trustfires but the AW cells work just fine, I was expecting it to go poof but i guess like timmo said its a voltage regulator and doesnt affect current. Now im off to play with my new friend (how much did this cost again...Ohhhh.....will a kidney cover it?)

It's a crapshoot whether your protected cells will fit or not. A lot of folks have been using unprotected Li-ions in the A2 just for that reason, but there is a big risk. AW's IMR cells fit without issue and they are a safer chemistry if something goes wrong. I think they are the best option out there right now, especially if you have a strion lamp in there. Whenever the new Li-ions come out with 10x the capacity, I'll recommend those instead....

Just got home and tried a 17670 with the strion kit,
No joy, barely a glow. just so you know.

Using two unprotected RCR123's, 3.5-4.2 volts, the cells will run out of mA's before the voltage drops too low, and you will notice the drop in output.

Exactly. The IMR cells fit perfectly like primaries. Protected cells may fit if you remove AW's sticker, but it's tight.

The A2 regulation circuit is a buck circuit and I have experience no problems with my leds (Nichia GS) or Strion bulb.

oo:....I want a bunch of those!!!
