@ coherent. DTR stated that heat issues strobe slowly while current is the fast one

Most handheld DMM's max out at 10A. I've checked my current draw on most of my builds and have not seen this problem using the meter. I am using a microboost it 3 of mine with no issues.

Yes fast strobe = not enough current. slow strobe = overheating.

May I ask what type of meter you use?
Mines an "Automotive meter" but It tends to work good on everything. Sadly it cant take mV readings above 1V which makes test loads a lot less percise over 1A. Does anyone know how to circumvent this? (I am thinking different resistor).
Ignore that. Its offtopic
Ill figure it out later

It says 10A but it wont read over 2A without freaking out. It works great for my linear drivers but my boost drivers set to 1.5A or higher is a no go.

After a quick search, it appears that a few others have seen the Microboost also do this with "charged batteries":
At 4 Volts, the microboost should NOT be strobing.
Most 18650 cells will drop from 4.15 to 4.00 VDC with 2 amps or so of discharge current.

It's a cheap Fluke knock-off Victor VC97
Mine will do well over 1v on the millivolt scale

Maybe its just your meter? I got mine as a gift. Was expensive so I dont think it should have any issues

Mine. Yes it was cheap.
I have not broken down and gotten a Fluke yet.:beer:
Anybody seen a good inexpensive one?

@ Larry, I tested the batteries after and they were still above a lot. Are you talking about as it is drawing?
The Boost Drive says its good down to 2.7V. Dr. Lava is gone though so its hard to confirm.. http://hacylon.case.edu/ebay/laser_diode/Micro_BoostDrive.php

My host from The Ehg Man should be here tomorrow where I will be building one with a Flex, I will be able to report back whats what once I get that all set up.

Both you and Kevlar were running microboost drivers at 1.1 and 1.2 amps.
The microboost PDF manual says maximum current of 1.0 amp when I looked tonight.
I have not seen any battery problems like this, out of hundreds of batteries running lasers and other "hi-draw" lights.
I think Dr. Lava builds good drivers, but this flashing at 4.15 VDC battery voltage is not correct.

I didnt do any tricky soldering or anything, just what was on his site posted in the PDF. Do you possibly know what It could be though?
Because It is something with these batteries because the AWs run like a champ. Only when they go dead do I see the slow strobe from the AWs

Not all AW 2600 batteries run the driver like a champ:
I think the wrong component is getting the blame for the strobing.

There is so much more data I posted... I will make another video I guess
