Sanyo 2400mah @Fasttech

Has anyone tried these? I have found only limited info on them. Maybe they were used in Xtar 2400? Not sure, but at that price it is hard to believe that anyone would buy crapfires or even Trustfire flames for that matter.

What do you guy’s think?

I wouldn’t have any qualms about purchasing those cells. You can’t go wrong with Sanyos. If you have a light that runs efficiently, and doesn’t require higher capacity cells, I’d go for it. I think my Olight S20 would be a good candidate for these. I put a Panasonic 3100mah in it two months ago, and its hardly made a dent. I think I have enough high capacity 18650s now. In the future I’ll save some money and go with smaller capacity cells like those for my everyday lights that don’t suck up a lot of juice.

Well you can call me tight if you want, I prefer careful. :wink: But I divided the cost per cell into the capacity and these are by far the cheapest per mah. For Nearly 10Ah for $16!

Just a shame there doesn’t seem to be any reviews on them.

Marc.

Are these cells safe to use in multiple 18650 lights (SRK)? Are non-protected 18650’s in general safer in single cell operation?

It’s probably a better idea to use them in single cell lights. I shouldn’t speak though, lately I’ve gotten some multi cell 18650 lights that won’t fit protected cells, so I’m running unprotected…I think I’ll go check up on them right now.

I believe Fasttech is selling genuine stuff, so I would trust on HKJ´s numbers on this case.

These batteries are good for single 18650, High draw flashlights.
They keep their voltage high very long and have a “steep knee” at the end, voltage drops fast then.
OTOH, if you want your single 18650 light to fade away a bit before getting empty, then go for thos 2900, 3100, 3400 etc batteries. They usually have not so steep discharge curve :slight_smile:

I use the Sanyo 2600 in my BC40 with no problems. When I pull them out to charge, around 3.7v they both read the same voltage.

I think you will find it is possibly safer using Quality unprotected cells than protected crap cells. I don’t trust many protected cells, as there is no real way of knowing the PCB is working properly. I like to keep it simple.

They are not on there. Just the 2600mah. Unless they are used in the Xtar’s.

Marc.

I wouldn’t sweat it. Sometimes too much research just muddies clear water. I, personally, would buy them.

They may be old cells. I think that Sanyo/Panasonic do not produce 2400mAh cells anymore

Oops, they were “just” 2400´s. I didn´t notice that.
Anyway, I would probably get them if in need, price is too good to skip.
I would think they are of better quality than TF “flame” 2400´s but lower price (by a hair) and no protection.

That’s my only concern, unless Fasttech can verify the age I think I will get another pair of 2600’s. Only a couple of dollars more.

Marc.

Yep, with 2$ added, I would probably take them also…
Actually I ordered 2pcs since I have 0 of them now…

My choice would be this or this
if you don’t want unprotected cells for some special reason!

http://www.torchythebatteryboy.com/p/18650-batteries-chargers.html The Sanyo 2250mah cells are tested here and beat out all the 2600 crapfire junk. My laptop pack died and I just got 6 of these from it in great shape. The 2400 Sanyos are probably dead centered between these and the 2600 the way all the Sanyos seem to test?

I don’t really see the need for a PCB. All of my torches have protection and I have smart chargers that terminate @4.17v. The problem is you get a quality Sanyo cell, but you have no idea what kind of quality the PCB is. You also lose efficiency with a PCB.

It’s only my opinion of course, but I just don’t think they are needed with a good quality cell.

Marc.

If the Xtar 2400 is a Sanyo cell, then it actually has slightly more capacity than the 2600 cell.

I will order a couple if they are quite new. But if they are a couple of years old, then I will pass.

Marc.

How will you determine how old they are? Great price, and I would like to know also.

They should have a date code, but Fasttech can’t find them. Yet.
