【convoy】H4 and B35AM options are updated

Where can I find such soldering iron?? I bought a soldering station which supposedly reaches 480C. But anytime I try to change LEDs of any light, it takes me at least 10-15min of heating and poking just to melt the solder. The host sucks up all the heat instantly. It gets really frustrating sometimes.

Are you using flux?

Yes. I realize that 80% of my problem is really me. Something I’m doing wrong. But yes. I use flux, always cleaning the tip to remove old solder and oxidation.

I prefer the first one,
I don’t want the buyer to spend more on the charger,

search “T12 soldering station” on any shopping site

I see it like this:

  • If you convert a 26650 light that already has charger to 26800 - great, that’s the lowest cost option for the customer
  • If you convert a 26650 light that doesn’t have a charger - customer has to spend extra (unless they already have a suitable charger or are savvy enough to use wires with magnets combined with any charger). Overall - not as good as the option before. Also, no matter how you warn users about the cell being incompatible with most chargers, some users will miss the warning leading to a few negative surprises.
  • If you refuse to convert a 26650 light that doesn’t have a charger, the customer won’t have a choice to run that light with 26650. For a customer that might want to do this - that’s actually the worst option.

That’s from the customer point of view, naturally. I have no idea which option (and whether any of them) makes most sense for your business, just wanted to show you another view.

Are you referring to heating the +/- leads ? If you are, I find it much more effective to “tin” the end of the soldering tip with my leaded solder, then holding it right on The soldered connection (usually its at a weird angle to get good contact of the flat part of the tip) while at the same time gently pulling on the wire with my need nose tweezers. Hope this helps. Pm if you have any questions.

Make sure you’re using something (I often use a toothpick) to separate the MCPCB from the host. If you are indeed heating the entire host as you say, it’s going to be a bad time. I usually prop up the MCPCB so one edge is still resting on the host and the far edge is leaning on the toothpick, leaving the MCPCB sitting diagonally in the cavity. Then I remove the LED +/- wires.

Argo, that first option you list then makes that light a recharger for the other lights that don’t have a build in charger. This would be one of my options as I have the M3-C along with the M3 and L2. Second option is my current one with 2 Olight universal magnetic chargers. I need the extra run time after the Texas ice storm many items used up their charge without stable back up. 26800 gives me 25% more runtime. I tail stood a few lights to illuminate our powerless station and my home.

Thank you Simon!

That’s actually a good idea! I’ll try it next time!

Thank you!

Thank B’harni (pbuh!) I had a coupla those Zanflare lanterns when I had a 1-day blackout around Christmas. Had nice WW light when I stuck it (magnetic base) to the doorbell frame. Could’ve used some Q8s for ceiling-bounce if it came down to it. Even the cats had light right over their litterbox downstairs from my Wuben E-whatever with the mag-tail and diffuser, stuck to the pull-chain-thingy right above.

But just for a regular handy-dandy utility light, something like an L2 or L6 would make a great base for taking a 26800. All it needs is a little extra lebensraum for the cell inside the battery tube to stick an ’800 instead of a ’650.

So either longer but still beefy springs, or an insert (like the “FT-to-BT converter disc”, only thicker) if using a ’650 to make up the difference, would allow both ’650s and ’800s to be used.

Or maybe cheaper, long/short springs, press-fit into the tail for a sideswitch-only light (contact-only tail, no switch).

I had and still have an assload of 10AH to 25AH powerbanks in case anything need recharging. Made sure my phones were topped off when the blackout hit.

And I just got last month or so a dinky little solar-panel to help things along if needed. Direct power and usb out if needed.

At present, when I am designing a new flashlight, I have given priority to adding a charging port for the flashlight, so I only need to produce the corresponding battery adapter tube.

Hello Simon,

I would still ask for the B4-40E. If it is already available as bare/16mm star/20mm star purchase in the LEDs section of your aliexpress store, I can not see, why you can not offer it as a tint option for the mentioned flashlights.

I acknowledge, that there may be a price difference between the 4000K 70CRI XHP35 HI emitter and the B4-40E XHP35 HI emitter (which I am ready to pay), but I don’t need more 4000K 70CRI, this is why I would like to ask for the B4-40E to be installed already in those flashlights.

I would like to thank you very much if you can make this possible for me.

Hello Simon,

That sounds great! Also at present, one of your largest competitors is ignoring its customer requests about making 26800 adapter tubes for its flashlights. I will buy MANY more Convoy flashlights from you after they have 26800 adaptability and charging port.

Also please remember to make an adapter for your L6 lights to accommodate 2 x 26800 cells.

Thank you so much for listening to us. Its always a pleasure doing business with you. :+1:

The M3-C and M4U seem like perfect candidates for a 26800 tube, as they already have charging built in. Although a 26650 has plenty of capacity as it is.

Utterly roasts Chinese mystery Vapcell batteries but presses for battery tubes to support a format only made by mystery Chinese manufacturers. :question:

What the heck??? Why are you posting here and not over at the appropriate vapcell thread? Indeed, vapcell is a conglomeration of several questionable rebadged cells with ZERO customer support after selling large quantities of failed cells to the masses. They have a growing history of doing this and should be the last place anyone should shop for cells… sans the desperate shills/fan boys.

And since you didn’t ask and decided to assume, there is no mystery as to where most of us acquire 26800 cells and why they are fast becoming so popular. They are a quality product with great consistency from Queen Battery. Search and read the many flawless reviews for the QB26800 and you will learn why they are a consistently great performing, high capacity cell in high demand. Also priced appropriately.

Well said, rewrappers like Vapcell are not at all equivalent with Chinese OEM li-ion manufacturers - many of the latter having fantastic products and QC.
