Sanyo is another top notch Japanese cell. The main difference between the 3500mag, we call it the GA, and the 30Q is that the chemical mix inside is optimized for higher capacity (500mah more) and the expense of supplier lesser amperage. There is always a tradeoff among these top brand cells.
For instance, if you want more amperage you can use a Samsung 25R. It’s capacity is only 2500mah, but it can pull more amps.
So you can choose a battery that best suits your needs. For instance, some of my lights are limited in output, like a headlamp, and I need to longest runtimes possible. I may only run it at 500 lumen, but I need it for hours. In this case I’ll go with a high capacity cell like the 3500mah GA.
If I have a high powered light that can do 3000 lumen, I tend to go with a lower capacity, higher amperage battery.
I hope that makes sense.
Oh yeah, there is another person who tests a lot of cells called Mooch. He’s mostly on e-cig websites, but you can search the battery model and “Mooch” and find his results. He’s tested cells HKJ has not (plus a lot of the same ones), so between the two you have a better chance of finding info.
Not only are the 30Qs great batteries but they are typically the most reasonably priced from retailers like Illumn.com (my favorite place to get batteries/ lights). Not sure where Cloud is located but I am a big fan of 30Qs for the price, quality, and power. I have some GAs too but they are usually for headlamps or my Nichia lights.
I never got to picking up an MF01S but I’m very curious. I do have an emisar D18 with XPL- Hi and would like to know how they compare in terms of the sustainable output. Can some mf01s owner share what sustainable lumen level the mf01s goes to after a)1 time turbo application 2) without turbo application ( starting from on that sustainable lumen level)?
Thanks!
Does MF01-S work with the 8x18650 tube? I don’t have tube, but does it put out 9v? I assume it puts the two sets of 4 in series… the MF01 non-S input voltage has a range up to 9v so that’d make sense. MF01-S doesn’t have any input range given?
The existing Astrolux extender works in parallel not series with MF01S just like with original MF01. You will need to buy additional one end cap and have two loose battery cages since new MF01S changed design with integrated battery holder.
The vast majority of the heat is at the far end of the head, above the switch level. So the battery tube heat dissipation is very small. I doubt you will see much heat related difference with a longer battery tube. Any difference will be tiny and you might not notice.
Turbo stepdown should not change.
Depending on batteries, you might see brighter Turbo output which means it could heat up faster.
I think the main goal of using 8 cells is just longer runtime. All run times double, except where heat might cause it to ramp down.
I have two MF01S (4000K and 5000K) using the astrolux extender tube (about 20€) and they work nicely! The original MF01 worsk with it as well and the MF04 ditto.
No Problems whatsoever.
The main advantage is longer runtime. In real world I don’t see an output advantage (i.e. more light on turbo) but turbo can be maintained a little longer…
But be aware, this then is a heavy flashlight and no beauty since the tube is nearly as thick as the emitter end
Cool just extender tube, extra caddy, and tailcap in… hooked it all up and yeah works just great. Yeah its mostly about runtime… I’m pretty sure output is a bit higher as well. I can’t really see a difference, so its not huge deal, but just based off heat its driving leds harder. I had setup ceiling to be at point where light just was slightly warm in hand, was like level 100/150 or something. Switching to extender tube same level is now noticabely warmer, so more amps must be flowing due to smaller voltage drop with twice batteries in parallel.
