new edc triple xhp70 not firing up

Between my friend and I that’s 2 and then Vnre and I used. Multimeter.on diode mode and all was good from tail switch to emitter I tried Samsung 25rs with a homemade sleeve ,and you can’t get to the emitters without damaging something. So that is why my friend who bought them is returning for money and my responsibility was to buy the batteries which h were the AWT 75 A s brand new 6 each

Did you look up the review from HKJ on those cells? They’re most likely your problem…

Or HERE

A screenshot from HKJ’s site…

This is AWT’s 3800mA 26650, not the 4500 like you used. Everywhere I saw yours was showing $10 ea or higher. Maybe you got scammed? At any rate, this lower capacity cell shown in the test sucks at higher amperage and the lights creds show 3*6A, that’s 18A in my book.

These aren’t efest they are the AWT s and he did a test on the AWT 18650 high drains over 35 Amps I wish I could find it but I can’t any how the lights are GONE my friend is returning

Dude, the red lines are Efest Purple 3500mAh cells, the blue lines down at the bottom are AWT 3800mAh cells. Essentially, the blue lines show the cells dropping below the emitters Vf requirement almost immediately. Won’t run the XHP-70. I have no idea what the driver is doing in that light, if it’d help a lesser cell work or if it’d shut down due to “low voltage protection” under load.

Also, the cells you listed are not 18650’s. They would have much different behavior patterns, as all brands show with different cell sizes.

Tell where this going to turn into an argument anyhow I tried 3 Samsung 25 rs in series with a pvc sleeve nothing and then I. Checked 3 AWT 266t0 in series 12.67-12.7 volts and what I was trying to sy HKJ did a test on 186t0 high drains and it tested well so WY wouldn’t the 266t0s if can send HKJ a battery let hkj Test it if he wants I will because Iam curious to see how they do and the bottom lin e the lights are gone I don’t have them my friend took them back and returning them and also Vnre s light didn’t work either so all 3 lights failed?

Didn’t read the whole thread but I have one of these except with XM-L2. Protected batteries were too long and were shorting out on the driver. Had to use unprotected batteries and use a spacer(a few coins). Unprotected were too short without the spacer and protected were too tong.

No argument, just trying to make sense of it all. I know that you can’t look at the test results from one cell and expect the same from another from that manufacturer. It might do as well, it might not. Typically the bigger cells can’t do as well in total output, although they do have more capacity. The Efest cell is the exception.

At any rate, I still agree that it was probably something relatively simple to fix the issue. Shame y’all sent em back so quick. Oh well. Happens that way sometimes.

I got started modding with an HD2010 that didn’t work out of the box. Every fix I did the dang light managed to come up with another reason to quit working! So I kept fixing and kept fixing til it was finally satisfactory. That taught me a lot, took some time but gave me confidence. :slight_smile: Then Old Lumens did the challenge and I found that one can do almost anything if willing and patient. I’m still not an electronics guru, so the drivers stump me sometimes. I just yank em and stuff an 17mm FET in and carry on. :wink: (of course it’s usually not that simple, but that’s the fun, the challenge!)

It and do what you said and try to figure it out but my buddy wanted send them back since it was in his credit card now Iam a little resentful because I bought 6 brand new batteries 26650s and nothing to use them in

The standard ShengJie XM-L2 would be a good one for those cells of yours. The light is about $75 and is very nice, it’d be a great long run time light for emergency type use and a club for those iffy situations.

Do you have a link?

Thanks Vnre I just want a mega light I don’t even have any more fun c8 any more I started last month with 12 lights now I have one sipik 68 zoomie and I never owned a big light so I’m trying to get one

That’s cool I have made 5 unfire 68Bs with this direct drive. https://www.fasttech.com/p/1114502 and xplv6 lions for other people when I went to make mine I fried 3 of them of my own so inly one I have running is stock one and I tried to hop up my c8s with XML2-U4 FROM Rmm And direct drives friends all the dd fet driver except 2 for my pastor finally got fed up and threw my soldering iron in the trash along with c8 hosts and fried unfire68s

Hmm maybe lime DB SAID solder joints somewhere come loose?I checked with multi meter in diode mode and the driver passed I tried continuity test at tail and everything passes only thing I can think of is solder somewhere on emitters ?

That’s a single mode. Wouldn’t you want a 3 mode so you can go to lower power when it gets hot?

Yeh that’s a pretty decent one I looked at lck led out of Korea and feilong out of Aliexpress had some also give them a look a

The ShengJie tripe XM-L T6 still shows available at CNQualityGoods.com.

That’s where I got the one I have here, took a while though.

I don’t know what’s going on with those lights y’all got, if he says he tested em before shipping em I’d tend to believe him so if there were something wrong it would have happened in shipping. One of those things someone would just have to go over the light and find the issue.

I am just wondering what would make ago good host if I wanted to start from scratch to make a xhp single double or triple using 26650 batteries

I got my information about these batterieshttps://www.fasttech.com/forums/2197901/t/1602507/-/1batteries but you have to read down through link and this why I bought them

So what seems to be the issue with the one sent for repair?

It’s still hard to believe but I got a couple of pretty detailed pms from the member who is repairing your new light and told me what he found !This bad news for the vendor who I felt was respected here and had a good reputation and that’s a big chunk of change per light to have this happen 3 xs right out if the box.
