Thanks so much to VK-GX, moderator007, gchart, Sillen and everyone who responded to my question about recommended 14500’s for a Lumintop Tool AA 2.0 light.
I appreciate it very much.

Shockli also has a very nice 14500 available that would work well

Shockli, Keeppower, and Vapcell 14500 1000mah in HKJ’s discharge graph, all look like they’re rolling out of the same factory. Their curves are so similar with small differences maybe being changes in production over time. Any of the 3 would be a good choice.

If memory serves, Shockli slightly edged out the 14500 1000mah competition. But as you say, any would be well suited for the task.

There so close its not even funny. Differences in time of manufactor or slight differences in the anode and cathode material or electrolyte could make for those slight differences. Even a few degrees in internal cell temp can make a change in the numbers but the curve should look close to the same.
The shockli looks like it holds a slightly higher voltage under the load but that could be from slight changes as described above after the Vapcell was tested (they were the first to use this cell).

Yes - thanks. I was wondering this myself. I will get protected though since there doesn’t appear to be LVP.

LVP: There is disagreement. Above says no LVP. But Zeroair reports that this light does have LVP

Observed 3.04 v cutoff

Lumintop Tool AA2.0 Ti Flashlight Review - ZeroAir Reviews

Lumintop is now offering an updated version of the ever-popular Tool AA light - the Lumintop Tool AA2.0 Ti. It offers some neat features!

Est. reading time: 13 minutes

I’d prefer to use a non-protected 14500, but would do so only if it has LVP. So, any help with resolution of the disagreement would be appreciated.

It has lvp which was 3,05 V in my case

yooj · 2020-07-16T18:22:48.000Z

Thanks for the quick reply.

Another important thing to mention, the lighted tailcap (only works with 14500) has a high parasitic drain of 8,5 mA
It will eventually drain your cell (i removed the LED’s in the lighted tail)

Mathematically speaking that’s only about 100 hours using a 850mah cell.
A little over 4 days and the battery is dead. Is that about what everyone experienced?
I changed my current limiting resisitors to a higher value right after I received, so I dont know how it was factory.

gchart · 2020-07-17T01:19:49.000Z

I can’t remember how high mine have been, but yes, it was right along those lines. I was dumbfounded.

The EE must have been out that day the resistor value was chosen. :person_facepalming:

I think the Tool AA 2.0 may not have LVP, so maybe a protected battery is suggested?

Yokiamy · 2020-08-01T22:16:32.000Z

It has LVP set at 3V

nobody · 2020-08-01T22:38:57.000Z

So what if you don’t want the battery drain from the LED tail but you still want to use 14500 batteries? Is there a simple solution?

BOO5TED · 2020-08-01T23:19:55.000Z

Turn the head 1/4 turn to break contact.

nobody · 2020-08-02T00:27:33.000Z

LOL — don’t like doing that. Is there another simple option?

Yokiamy, can you please share the source of your information? because I dont know who to believe:

Just be aware that it doesn’t have LVP , I always use protected cells in the tool AA , I once ran down a 14500 to under 2 volts.

Indeed there is no LVP. To my knowledge, it quite a common practice on flashlights that use a boost/fet driver and accept both NiMH and LiION cells.

If you want to keep the tail light and use 14500, nope.

Don’t really need the tail light. Does that open up any other solutions?

BOO5TED · 2020-08-02T01:05:37.000Z

Yeah, just remove the leds so no lights at all on the tail.

nobody · 2020-08-02T01:10:57.000Z

I'll take a look at that and see if it is something I can do with my lack of skills. Thanks
