XHP70.2 should be fine but is the driver work properly at 11A?
this should have been driven to more then 4300 only, why only so little? i think the host can easy handle 5000+ and more no ? looking mats video its only about a 500 difference in lumens vs the old xhp70 emitter.
I put the 0 ohm resistor, installed a 70.2 (4000K) in my older L6 and kept the OP reflector in it, amazing performance. Not sure if I am going to de-dome it because I like the beam profile as is. I may do all the mods to a different one.
I just got myself the L6 XHP70.2 and fitted two brand new Keeppower 5200mAh batteries. For some reason, the flashlight doesn’t light up at all.
Do you guys know if it could be the batteries, not having a high enough max continuous discharge? These batteries do work on the L2, so batteries are definitely ok.
What batteries do you use?
If these batteries should work, then there is a problem with the flashlight.
Please help…!
Thanks 
Are they flat tops? If so, could not be making contact . Assume you used singles in the L2?
No, they are button tops. I’ve tested them both on the L2, 2 cell config, and they work.
Have the Keeppower 5200mAh batteries enough power to work on the new L6?
What batteries do you use?
Thanks
Oh boy, I got tons of 26650's, and let me see - I got one modded XHP70 with a BLF OSHPark board, and one pretty much fully stock XHP70, maybe XHP70.2. I typically use the blue covered 5000K LK's, but I stay away from KeepPower cells in general - rewrapped who knows, and their history of denials and not telling what they use has been frustrating.
Are they protected? If so, do you know the max amp ratings? Might be maxing out the protection circuit. I also generally stay away from protected - only use them for testing purposes. For example, I bought a set of 4 GA protected 18650's at the time for testing on the Q*, since many BLFers were asking bout protected cells.
The better protected cells nowadays have high amp ratings, like 10A to 12A, or thereabouts but dunno the ratings of KP's - hhm, should google up these 5200's....
Update: Ahhh, here they are unprotected: https://www.illumn.com/26650-keeppower-5200mah-imr26650-high-discharge-flat-top.html?gclid=Cj0KCQjwjMfoBRDDARIsAMUjNZoX5ZepAVoZUbwt2sv2bxZ84JAdjI-U3DrVXAdOldwfpPDv5skcPdMaAjByEALw_wcB
Here they are protected, and 9.5 amp rating: https://usa.banggood.com/Keeppower-ICR26650-5200mAh-3_7v-Protected-Rechargeable-Li-ion-Battery-p-961178.html?gmcCountry=US¤cy=USD&createTmp=1&utm_source=googleshopping&utm_medium=cpc_bgcs&utm_content=garman&utm_campaign=pla-usg-rm-all-purchase-pc&gclid=Cj0KCQjwjMfoBRDDARIsAMUjNZqZzKULLiP9Blxmkm7dq5QxG_e_s9Pbb7G9h3kY_j4EXGGyun6mhZAaApGrEALw_wcB&cur_warehouse=CN
So all depends... Hhmm. On a stock L6, 9.5 amps? Hhmm, dunno, might be close, might trip - it's rated at 4300 lumens, so dunno off hand -- any reviews post the amps drawn?
Does the light work at low settings?
Hi Tom E, thanks for your reply.
My KP’s are 5200mAh button tops protected cells rated at 9.5A max discharge.
These cells work on other flashlights. All I need to know is if these cells would work on the new XHP70.2 L2. If they do, then the flashlight I got is faulty.
Does anybody know if they should work at 9.5A max discharge?
Thanks.
No one posted amps readings, not even in the vid review of the OP. I don't have a new L6 XH70.2, but my old ones I should have notes on at home (at work now).
My guess is the 9.5A cutoff of the cells. You could try this: pop off the tailcap, try a long thin wire between the battery tail end and the no-anodized surface of the tube's end, compressing the batteries down. This maybe will drop the amps enough to not engage the over protection circuit.
Are you first turning the light on with the tail switch, then clicking on the side e-switch? You do realize the power tail switch must be on for the light to work? Might be a dumb question, but good to check the basics.
hm, see this video perhaps its of help… the batteries should be ok and so the flashlight…
Got an L6 running those protected Keeppowers all fine here.
Is that L6 the XHP70.2 version…?
Yes the 4300 lumen one with smooth reflector.
Use it regularly when walking dog at night.
Thanks Fluke. All I needed to know. It seems I got a bad sample L6
Double check that the little beauty ring that threads on the switch side of the battery tube is tight. If it’s loose at all in can prevent the tail cap from making proper contact.
but are u sure ? what about the ring on the tailcap, is that fully screwed down ? and u press the tailcap and then the sideswitch to turn it on and nothing ?
Do you have the tactical grip ring on it or the normal smooth ring?
If your getting NOTHING at all it could be that the ring on the end of the body is slightly loose. (see video mortuus posted) The new L6 should be perfectly fine on the kp cells. As far as I know it uses the same 5 amp driver.
Problem solved…! it was the damn ring at end of the body that was screwed backwards, hence preventing the tailcap from making contact with the body. It got me too…!!
Thanks for the input guys…!!
Good Lux 
Cool! Sorry, it's been so long since I fiddled with my L6's, forgot about the ring issues, but holding a simple wire jumper across the battery "-" end to the tube would have narrowed down the issue much earlier. It's a common thing to do, and one of the first things I do in trouble-shooting any DOA type problem to eliminate contact issues at the tail.
