Review: itp A3 eos upgraded

Keep an eye on the self-discharge it may well have increased and doubtless the capacity has been reduced.

A lot of protected cells don't cut off on low voltage anyway.

My guess is that the voltage dropped enough for the light to cut out (Lithium ion cells voltage can sag like crazy under load) and it decided not to restart when the voltage recovered once the load was removed.

Keep a very close eye on it when charging though - it is when charging that cells are most likely to blow.

If it can hold above 4V for a couple of days after charging it'll probably be OK.

So I guess you mean I shouldn't repeat it ;)

Still not intuitive, as 3,5 V is not a deep discharge, is it?

Or do you mean that it falls much lower under load and THAT is what is dangerous?

I reckon it probably went down to around 0.8-1.0V - recharging from that low can be a bad idea. But once the light was off, it couldn't turn itself back on as the cell voltage recovered.

That's my guess anyway.

The voltage does't fall off linearly at that level. If you have a resistor, you can try measuring what the voltage went down to with a load.

Kind of weird the light was entirely off given it's a boost circuit. The battery must've gone to really low level.

While on this subject, back on Aug. 10, I got 3 dead laptop battery packs from friends. I took them apart (first time ever) and all were 18650's. 1 battery pack had 4 red Sanyo's, another had 6 pink Samsung's and the last one had 6 blue LG's (i think). I checked their voltage and the 6 pink Samsung's were all 4.11v which is pretty good. The blue LG's were all 3.98v which isn't that good but not that bad either. But the 4 red Sanyo's were all around 1.45v which I would think should be instantly recycled right?

So anyway, I charged all 4 and they all went up to 4.21v which is great but I wondered how they would hold their charge. After 1 week they dropped to 4.2v, 2 weeks down to 4.19v, 4 weeks down to 4.18v, 8 weeks down to 4.17v and now after 10 weeks are down to 4.16v.

So what do you guys think? Recycle them or keep them?

Thanks.

That's pretty good. I have a bunch of good green sony's from a toshiba pack, and many mediocre sanyo's from lenovos.

The most annoying thing about these batteries is that they're tabbed so you get the little pips after taking them off. Perhaps I should just cut them off on the side of the tab. The flat tops also make them hard to fit or won't fit lights without a spring on the + side.

I peeled off the tabs with needle nose pliers and grinded down the leftover pips with my dremel. They don't look perfect but are good enough especially since they were just given to me by friends. You just can't beat the price of $free.

Off Topic but in a good cause. Being a heavy smoker for the last 20 odd years and a social smoker for a few years prior to that i felt i would always be a smoker and gave up trying to give it up. However i have not smoked so much as a single drag in the last 3 weeks and i don't feel the need to, how is this possible you ask? well i bought myself an e-cigarette NOT to give up smoking but to take care of the craving while i was at work and unable to smoke, it worked so well for me that i stopped smoking altogether. e-cigs are basically battery holders with switches just like our flashlights but instead of the lamp / led it has a small coil which heats up and vaporises a mixture of water / glycerine and nicotine which is then inhaled and relieves the craving without the tar and thousands of toxic & carcinogenic compounds found in tobacco, so in essence i gave up smoking by accident and so far it has been all gravy, although to be fair i have simply changed the way i satisfy my addiction but i am quite happy to go on inhaling what is essentially water vapour with nicotine in until i drop dead which will hopefully be a few good years later than if i continued to smoke tobacco. Another plus is the fact that i can smoke in restaurants , cinema , football match , on planes trains and in automobiles ;) and even better my non smoker wife no longer complains that i spend too much time out in the workshed (smoking) and i can sit down and watch TV without constantly being reminded that i smell like an ashtray :D one major downside is that i have spent 3 months worth of flashlight budget on vaporisers and various e-juices and have not yet got a Stainless Steel e-cig! though i do have a very nice aluminium and brass one, and another in bronze.

Just a heads up Don , may work for you and the startup cost was negligible (£20-30) for everything i needed and spares of everything too so for the price of a couple of budget flashlights you could just possibly kick tobacco into touch and have more years ahead to appreciate flashlights, oh and the cost of the e-juice is around £2.50 for 5ml and they claim that is the equivalent of 50 ciggarettes for me it is more like 60-70 but YMMV so may have an increased budget for more flashlights.

Couple of forums with good info on.

http://e-cig-reviews.com straight talking reviewer and of those items i have bought based on his reviews i have to say they where spot on.

Take care.

I found my lost light in my front yard today! After a month and a number of rainy days, the light worked just fine. But I already bought a replacement, then I jumped at a chance to get a used one in titanium, so now I have 3 of them!

Where can I get the Ti version at a reasonable price?

I got mine used for $25 from someone at CPF, which seemed kind of reasonable (compared to $45 new). It has a few scuffs on it, but otherwise is fine.

Just a note, the iTp A3 upgrade edition is on sale at goinggear for 15% off.

Not exactly a budget AAA light, but one of the most positively reviewed ones around.

Virus warning on first image ....

Btw.. have you seen the Maratac AAA Cu?

Made of solid copper.. I wish there was an ITP version of this light (i mean, cheaper and free shipping)

The first image at GoingGear? Makes no sense...

Id Hate to have one of these, for the reason that it will tarnish :/ Cant actually handle it without gloves specifically for that torch!

I do prefer the mataracs! which is to me the more expensive and difficult to get option. ITP are readily available from HKequipment for example.

Im not sure if these are the right versions (Q5?) upgraded?

$22 Black

$31 SS -

$40 Ti -

The pwm on the q5 upgrade is so bad the light is useless .I agree with the tank 703 but like the 701 as much maybe more ,cheaper different tint ,less light but not much .I have mixed feelings about the b3 n-light which I agree with vectrex you worry about losinga 30$ tiny light .I have 5 - 701's @ 6$ and 5 - 703's@ 8$ each they are much easier to use or lose I like the eo8 tank as well .. great lights //hate the itp..One of those lights I just never want to use .I think even if I had the newest model with no pwm I still wouldn't like it .

Has anyone ordered the newer ITP A3 EOS R5 from Going Gear?

I just received mine, but it was a packaged in a Q5 box, with Q5 instructions.
Can someone tell me the difference? I'm worried they might have sent me the Q5 version, which is cheaper. Thanks!

EDIT: Whenever I switch to Medium, it flickers like a strobe, until I give it a little shake. Only happens when I switch to medium. Any item why and how to solve it? Thanks!

They always send it in a Q5 box, but with an R5 sticker.

Regarding the flicker in medium mode - I've no idea.

Whats the difference between the looks off Q5 and R5?

My LED is a square divided into 4 equal rectangle. Is that R5?

Thanks!
