groupbuy: Astrolux MF02S SBT90.2 (600kcd) ONLINE

Unfortunately, the MF02S v2 coupon has expired. Could you give me a new one?

Almost 6 months later, can I have a coupon lol

The groupbuy has ended, but the flashlight is still available. Where is the problem? :slight_smile:

No problem, just found it amusing after so long.

Just got kind in last week, love it but notice 30q’s I have won’t hold turbo once they get to about 3.5v each, or so. I may have a bad 30q unnoticed when charging, but that’s a different problem.

Question to anyone who knows-

Can you use flat tops in this MF02s V2? It looks like you can with the brass tabs in the battery tube, it I just wanted to see if anyone has been successfully doing this before I order some Molicel P26a flat tops.

Thanks!

Flat tops work fine :slight_smile: sold a couple with flat tops.

Turbo requires 35A (from memory) and at 3.5v the voltage drop/sag would be unable to allow Turbo.

oh man, thank you Funtastic! that is great information and i really appreciate the quick response to this, very helpful! Looks like P26’s or VTC5a’s are what i need then.

Also, i really enjoy the YT channel, i think it is you that has been posting great thrower reviews lately, convoys, etc? If not sorry, but if it is you, keep them coming they’ve been helping me a lot!

I believe the earlier MF0x models use this kind of battery carrier (with a plastic washer which prevented most flat-tops from making contact — an added protection in case battery is inserted incorrectly)

Newer MF0x series likely use this kind of battery carrier, so flat-tops work now (but be careful not to insert battery upside down, which will create a short and will just burn out the springs, assuming not-so-worse case scenario)

Why anyone would inset the battery upside down is beyond me. The spring side has always been the negative side for decades.

That is a good comment DTA made and reminded me that there’s a long version that uses 8x 18650’s. Do you have the short or long version? The short version can use flat tops no problem, but no idea on the long version.

I haven’t for a little while, but have got a few on there of the Convoy’s. I have another on the way of the Convoy Z1 with Osram CSLPM1 vs SST40 since I can’t find a video of it.

DTA - the short version doesn’t have a battery carrier, only the long version

Sorry, I made a mistake.

I don’t have an MF02S v2 at this time… the pictures were from an MF02 battery carrier and MF04 battery carrier — I thought the MF02S v2 used the same battery carrier as the MF02 and MF04, but it looks like they don’t.

Yes, thank you dta, that is good info.

I have the short version and it does not have a battery carrier, it is “built in” with the tailcap having buttons and springs and a mcpcb screwed in at the head side of the battery tube.

But to agree with Zoulas, I have always wondered how people insert the batteries in the wrong way (i just read a comment a week or two ago about someone ruining a $300 light that didn’t have RPP because the battery went in the wrong way). I guess if you just aren’t paying attention because putting batteries in seems like such a menial task that would make sense. i hope it never happens to me!

yea different carrier because of the 6v / 12v xhp series ( i believe) vs the 3v sbt90.2 although the sbt90.2 is 2s2p, so in actuality they may be the same. Maybe someone else can confirm, i used to own the mf02s xhp70 but i dont remember exactly how the carrier was.

Sold a Convoy 4X18A and the customer reversed one or all of the batteries, killed the light and drained all 4 batteries. Lied about it, and so now I include clear instructions and a warning that warranty will be void if they get the polarity wrong.

Damn! that sucks… I wonder how often manufacturers have to deal with that? Im sure way to often… just amazing…

Had one guy that already owned a Convoy L6 reverse the batteries on the new unit I sent him. Well, while talking to his partner he chucked the batteries in wrong, killed it. I refunded him and sent him down a new one as he wasn’t “sure” that’s actually what he did lol I tested it before sending so that’s exactly what happened.

Everything that I sell gets tested twice, once on arrival and again before shipping out. Only 5 customer warranty replacements in 7 years :slight_smile: a lot of work though. I clean the contact points, lube threads, and make sure retaining rings and screws are tight, also install dual springs instead of the factory spring bypasses

Sold another L6 to a nurse at a medical center I often visited. She didn’t even read the instructions and inserted the batteries wrongly, thankfully I swapped the Convoy driver for a Sofirn SP70 that had reverse polarity protection.

Very interested

Interested is the code still valid?

I’ll verify, I received this light 2 weeks ago, it’s AWESOME. My advice, don’t run 30q batteries, I’d run molicel p28a, I already bought a set their on order to replace my 30q. The amps needed is too high for 30q in my opinion, turbo isn’t utilized properly for long enough.

EDIT: I have received and i am running molicel p28a batteries, they are MUCH better in this light than 30q’s, and I notice no difference in battery life. but it seems the p28a battery life is better, i’m assuming because it delivers higher amps longer.

Any active coupon (short version)?
