I ordered an L2P for my p60 drop-in (which will be shipped in a couple of days hopefully), along with the KD C8 of course :)
Pity, KD sent an SDHC adaptor instead of a 3A 2x18650 driver. I'll have to postpone my double battery XM-L project. Everything was ready, TR1200 body, MC-E reflector and a T5 star. I almost knew that they wouldn't meet at the same point. :)
Could be the cells, could be heat. If I can rig up a current probe, I can stick it on the lightbox and measure current from the cell. Still can't get the meters to play nicely with Linux so that I can log more than one thing at a time.
No, I'm a Mac guy but have Solaris, Linux, Windows boxes around. Until earlier this year, I was planning to replace my Linux fileserver (with 11 year old hardware in it) with a box running Solaris and ZFS.
These days a fileserver is a lot less necessary than it used to be with cheap external hard drives and a gigabit network.
The software is not great - internally the meter appears to have some sort of strange UART in it, with a USB converter half-heartedly bolted on. The meter appears to be a rebadged Peak Tech 4390
The place I got it from no longer sells it unfortunately and has deleted the links to driver updates.

Oh the old trick of a old standard serial communication system spit in the face by a half assed usb to rs232 converter... which probaby install itself each time you change the usb port. :/ (COM port 22 and counting...)
Ordered YJ J01 at the first glance. Cancelled my KD C8 order as I built my own C8 last night. It was hard to find some space in a C8 body and the pill is crushing under pressure now. I hope this 1cm longer Eastward is better. 3 modes are still High, Mid, Strobe unfortunately.
Which 18650 battery did you use to test tail-cap current and how accurate is your meter?
The reason I ask is that I have several flashlights that are claimed to be driven in the 2,500 mA to 3,000 mA range, however when I check them at the tail cap I only get 2.0000A to 2.2793A (my KD Cree XM-L T6 drop-in) with my Fluke 189 digital multimeter with fully charged TrustFire Protected 18650 3.7V True 2400mAh Rechargeable Lithium Batteries
The meter's a very battered Fluke 77 Series 3 though the leads are aftermarket DX ones. There is a place locally that would calibrate it for me. At four times what I paid for the meter! I own several meters so I can easily measure it with something else. The Fluke is the one I trust most.
The cell used was a Trustfire unprotected 2500mAh - I seem to have hit on a good batch of those when I got 6 of them a couple of years ago.
I can easily redo the measurements with different cells and meters. Might be interesting for my own confidence in them.
I finally recieved my XM-L from KD with the skyray host for 25,55USD. Did the foil trick. Left it tailstanding at full brightness on desk for about 10min. It is scorching hot! Draws 2,86A.
I think exposing lithium batteries to 60C or more is a bad idea. Maybe on my bike it will hold on high.
