[♛ FreemeGB] Long Battery Tube for ASTROLUX MF01/ MF02/ MF04 Series >> ALIVE

Too bad, that I didn’t make any pictures or video footage before trying to hammer the dent.

I also found, that the battery carrier came with this tube, is even shorter, than the original ones. My guess is, somehow, the outer ring section is not pressed enough to make a contact, therefore the negative part is to blame. I will try to make the tube a bit wider at the dent, because maybe one of the carriers is forced into a slightly tilted position by the dent, and thus, it doesn’t make good contact.

@adam7027
The tube is reversible, did you try to put the dent on the tailcap side with the loaded battery carrier on the head side to make good contact ?

Definitely interested.

Please send me the coupon code if it's still available for the Long Battery tube for ASTROLUX MF01/ MF02/ MF04 Series. This is for Package including 1) 1x long tube, 2) 1x battery carrier and 3) 1x connecting "plate" for the carriers.

Thanks for providing us with great deals and tech.

I tried both orientation - if I manually push the battery carriers towards the head, the flashlight works (green switch light starts to breath), but not with the tailcap screwed on.

After I did some experiments, I guess, that if I install a heat resistant plastic ring into the tailcap to add a bit of more length, this tube should be functional regardless the dent it has - probably, who owns functional tubes and carriers already, also will get a better contact, if that ring would be installed.

Placing a second order.

Mine arrived, perfect working order. My package was double bagged, double wrapped in bubble wrap, and then wrapped in newspaper. Works perfectly on my mf01.

Thanks!

Mine arrived today.
Badly packed. It works but one end came dented.

I took mine today.

What about F04S,which takes more current?Is the tube good for this?

Add me to the list if the GB is still active.

Mine came wrapped in newspaper with bubble wrap on the inside. A couple small mars to the threads on either end of the tube from its journey through the postal system. They should have boxed the battery tube, I can see why others are having problems. Thankful mine wasn’t too damaged.

I’m really glad this was made available. I kinda felt left out when I realized the MF04 only came with the shorty tube.

I received my extension tube yesterday. The contact plate actually looks different than on the Astrolux fotos.

The new battery carrier is made of aluminium (the plates and the sticks) instead of brass, so it weighs only 59g while the older version weighs 137g. I’m not sure if the conductivity is influenced or stays the same.

The extension tube was wrapped with bubble wrap and newspaper but there was a dent on one end that needed to be cut away with pliers. Otherwise the carrier would not exit on that end.

Same lousy packing, no damage though, some scratches of course.
Not work first try, need to cut a thin cardboard, put inside tail cap then tighten. Bingo, green led on. :+1:

Interested

Brass battery carrier design has replaced with aluminium since MF04 model (early 2018). Not much difference in terms of performance.

I agreed, bubble wrap plus newspaper might not be sufficient. I left a feedback to Banggood few weeks ago. Hope manufacturer could come out with a solution with increasing the price.

So someone tell me, on the MF01, does this add run time, brightness, or both?
Looks like the original tube as two sets of batteries in parallel, so does this double the voltage?

Operating voltage is still the same as single carrier. [quote=scosgt] Looks like the original tube as two sets of batteries in parallel, so does this double the voltage? [/quote]

I am a newbie, so help me out here. The extension appears to load the battery carriers in series, won’t that double the voltage?
If not, what is the point of the tube? What does it do besides add 4 batteries?
Thanks

It’s not a series carrier.

It’s a parallel carrier.

It gives you 2x the battery life.

And to anybody buying the carrier, it’s actually better in terms of performance theoretically.

Not that it mattered anyway.
