I finally could purchase one, and today I received it.I now charge the batteries by a Nitecore charger at 2A,waiting to be finished,so as to see the beam and take some measurements.
I could say that turning it up while batteries were at 3.36V,the light which I saw on the ceiling,as it is daytime now here,is less than the modded by the BLFer giorgoskok, Astrolux MF01,which has a throw of some 85,000cd.
It is the throw I want to see as well ,after the charging is finished,and take some measurements on a Dr. meter luxmeter.
After finishing charging,I see that it is stronger than the older one,but I have to make the mesurements to see the throw.Anyway,trying to lock out the light,I see that while being locked out,it is blinking both,the green switch light plus the coloured leds inside.
Is it normal?
I have just taken a measure with a luxmeter,and I found that it is 105.900cd.Not bad,not bad at all…
Urgently need advice. Which batteries are best used for a flashlight. It is necessary that it burns as long as possible at maximum power.
Yes, you can cycle through some different modes if you choose.
In lockout mode click 3 times fast. This will cycle to the next mode. Low, High, Blinking, Off.
Maximum power makes the most heat so it burns a shorter time. So do you want max power (high drain battery) or do you want max run time on Turbo (high capacity battery)?
Максимальное время работы на Turbo
Shockli 18650 3600mAh. Do you think these are normal batteries?
Sorry, I can’t read it. 
Capacity is probably a bit less, maybe 3400mah. Discharge is definitely wrong, no way it’s 25A continuous. Probably 8-10A. Similar to the Panasonic GA I believe. So low drain, high capacity. I would stick to the big brands if possible.
I need an advice . Which brand to choose?
I don’t know your choices. Where can you buy from? What country are you in?
My choice for this light is a good middle battery like Samsung 30Q (I think button top are good for this model light) . It has good power plus capacity, is high quality, not too expensive and easy to find.
Thanks for the tip! I’ll have to see if Vaseline holds up to it, but I doubt it too. Aluminum shines up so nicely and the anodizing wasn’t up to par on my copy.
I have both,the MF01 and the MF01S,(in a wonderful silver colour),and I think that the switch of the new light is better.So,I ask if it is possible to change the switch to the new one.
I want to have handy the older light,because it has a strobe mode of 18Hz,as it is modded and it has both more lumens, different UI,plus 18Hz strobe.The latter,because this frequency is the more annoying frequency.
Is there a way to reset to factory?
The hold button while putting tail cap back on & the 13 click method do not work…
Why do most choose 30Q batteries? Are there really no better batteries? For example, Vbatty V30 IMR 18650 3000 mA / h, 40A. I'm confused .
Is Sanyo 3500mAh worse than 30Q
I think we need a special space for battery info ( and I’m sure it already exists on the forum) where someone could create a chart of batteries from best to worst, say in rows, and capacity in in columns for different battery types, perhaps there could be separate charts some taking into account max discharge rate or some measure of how well they maintain the amperage as the voltage sag, or could be shown by colors / graphs on the same chart. People could then submit results of their testing or voting and the majority’s info entered into the table? This could be accompanied by a short narrative/ manual as to how to choose the correct discharge rate / other parameters for the different light amperage demands. Perhaps this already exists in several places scattered thru the forum? Otherwise there will continuous be million battery question in every thread ?
“Best” usually depends on your use case. Do you want ultra-high discharge rate for maximum lumens but for a shorter runtime? Or would you like maximum capacity at the cost of discharge rate (sacrificing lumens for runtime)? Or is a higher voltage sag acceptable if you are cost conscious and want cheaper cells? There is no one “best” battery - it all depends on what you’re looking for.
BLF user HKJ does a wonderful job of testing batteries and helping us keep track of what batteries are good. He maintains a great website with in-depth battery reviews (in addition to other items) which includes a great comparison tool
See the answer above. Better or worse depends on what you want. If you want the extra lumens and shorter runtime, pick the 30Q. If you don’t mind giving up some lumens but gaining runtime, pick the Sanyo GA or Samsung 35E.
Wow, thank you, there is so much info there, you almost wish for less information to make a choice. A wonderful resource !!!
30Q is made by a top notch Japanese battery company so quality is high, it’s a great mix of high capacity and high amperage, it’s fairly cheap and it’s fairly easy to find.
Vbatty is a brand I’ve never heard of. HKJ has tested the 30V blus/gold and it’s performance is virtually identical to the 30Q. So it looks like a really good cell. It may even be a 30Q under the Vbatty wrapper.
Now the tricky part, is the cost and availability similar to a 30Q? Unfortunately I can’t seem to find it for sale anywhere.
