Review: Small Sun ZY-T08 2 x 18650 (Parallel)

I added a little solder to the edge of the driver, to make it a good press fit. No difference in out put, I also cleaned the anodizing where the switch PCB contacts the body, no difference. I fitted a pot, minimum setting was 0.5ohm, that raised the output from 1.94a to 2.43a on good cells, and up to 3a on crap ultrafire Greyā€™s, guess their good for something. :bigsmile:

Iā€™m waiting for johnnymac and viffer to get back on the readings of the pots viffer found.

Mine read 0.45 ohm - 49.5ohm in a 270 degree sweep.

The ones viffer found are rated 20 ohm and and 22 turns of adjustment - much better resolution.

You definitely need to get closer to .22 ohm.

Let us know if you find something. Iā€™ll probably be ordering weekend after next (payday).

OK.
While waiting, I tried it blindfolded with one 0.22Ohm

Now I get figures around 2.5 -> 3.2Amps or something like that.
I get once and a while the lower 2.4 something and when I cycle modes, it gives over 3 Amps.

Still I think it got better.

edit: those are with Trustfire Flames. Too bad I just ran out of proper Xtars, I will have to re-test when I get them againā€¦

Viffer said something about the circuit being very touchy with regards to resistance, so not too good cells give a higher reading.

I did find out I have to order some Panasonicā€™s or sanyos, the cells I thought were good have touchy protection circuits when you get over 2.2a. :frowning:

Got mine today.
Measured sometimes 2.7A, sometimes 2.0A on high (0.95A/0.45A for med/low)
Flux: 660lm/320lm/150lm
Throw: 33kcd/370m

Unfortunately I donā€™t know what current the light used at those flux and throw measurements, but the flux measurements didnā€™t have much variance.

Hm. I wanted it to be on par with the FF STL-V2 and sell that one (because I prefer the T08 form factor), but now I canā€™t. Iā€™ll probably try to mod it (when I find time for it).

If someone of you guys need a 0.22 Ohm resistor but donĀ“t want to wait forever ordering from China or donĀ“t have Electronics shop near you, PM me.

I can send some of those to you, probably wonĀ“t need all 20 anyway :smiley:

this is mine coming from manafont today. :smiley:
what do you think, is it a plastic reflector or alumunium reflector?

also my evgreen flat top battery wont work on this flashlight,

so iā€™ve been thinking to get this one Sanyo UR18650FM 2600mAh Li-ion or this one Panasonic NCR18650A 3100mAh Li-ion or i should go with the unprotected one.

which one would you suggest better for small sun zy-t08? :smiley:

H) :beer:

Plastic. Any button top cells will run this, but the smaller the button the better.

Donā€™t worry about the plastic reflector, it works, be happy.

now im really confusing about what battery to buy, not the very expensive one i think

what about this http://www.manafont.com/product_info.php/efest-sanyo-protected-18650-37v-2600mah-rechargeable-battery-pairset-p-11591
or

The above mentioned ebay pot looks good. 360Ā° full turn -> 0.7-0.8ohm, minimal resistance ~0.03ohm, max ~19.3ohm,

Thanks viffer, Iā€™ll go find the link again and order a few for stock.

Edit :- just ordered 8, Ā£2.54 8)

Canā€™t wait for them to arrive now, give this light the current it deserves. J)

Mine arrived last week but I havenā€™t had a chance to install any of them in any lights yet.

There is an ultrafire version which is the same as the small sun at Banggood for $24.99

Is that yours or a stock photo? If it's yours, any report on tailcap current, build quality, etc . . . ?

-Garry

It's mine, same as the Small Sun 2.02amps on with one battery.

Hmm, slightly better price, about $1, but will wait for further report on the quality.

Well, not like MF ones are consistently good anyway :bigsmile:

Iā€™ve submitted product request at fasttech for T08 and T13 before this, hope it gets through.

so, where to by a small sun-t08 best price?

manafont

thanks :slight_smile:

just ordered it, and 2xncr18650a 3100 from fasttech :slight_smile:
