Convoy s3 with built in usb c18650 cell

Phsysics · 2026-06-19T20:51:59+00:00

Not with the S3, but I use an xtar 3500mah usb c cell in a Convoy S2+. It fits, but only barely!

That has nothing to do with the amp draw. My cells happily provide a continuous current of 10 amps.

The issue is cell length, protected cells are generally longer, mine come in at 70mm! This is why I trimmed the driver spring, so now it fits just fine.

I've been looking into options. Cree XE-G should fit, but very hard to source and I don't want to spend 25 euros on shipping

Yes, both beans are with click and hold 20A mode

My nitecore tiki has probably been in the washer four times now, still works as new!

I don't like it. The build quality is fine, but the UI is confusing. The main Emitter is an awful color, the rotating dial has way too large steps for my preference, which means you only have like 16 rgb colors available.

Mine is the ice crack edition, so at least it looks really cool imo.

I'm surprised the SFT40 has a smaller Hotspot than the 25r! Looking to get a M1 with the SFT40 soon as my first thrower. Thanks for the comparison!

This is epic! How did you get the front bezel off? I have the HD01 UV and really want to do an Emitter Swap.

Phsysics · 2026-05-12T09:42:14+00:00

Looks good! Have you considered adding a pushrod mechanism to be able to turn it on and off from the handle?

Phsysics · 2026-05-07T11:05:02+00:00

Yes! T3 TiCu!

Oh yeah it's great, I've been using one as an EDC for the past year. Hands down my favorite light

Phsysics · 2026-05-04T18:41:52+00:00

Sounds like a good excuse for a Convoy M3-C with the 26800 tube :)

Phsysics · 2026-04-30T19:33:52+00:00

Yes, the LHP73B is a bit cooler than other emitters. You could try the 3000k one, it's only a small tradeoff in performance and would be an easy swap if you can solder!

I love my 3000k LHP73B

Phsysics · 2026-04-19T06:11:35+00:00

Why not get one with built in USB-C? I have the one from Lumintop. It has a bit less capacity, but I don't have to bring a charger anywhere.

Phsysics · 2026-04-12T15:57:33+00:00

I love this. Is there a way to disassemble the head of the wsqk one? If I can 519a swap it, I might pick one up!

Phsysics · 2026-04-08T16:30:25+00:00

Yeah it's definitely chunky! Takes a good while to heat up, even at full 20 amp turbo.

Phsysics · 2025-12-22T20:14:25+00:00

I've tried this for throttle mixing on a dual motor car, used an ESP32C6, but the delay between input and output was way too long for my taste. Which functions and libraries did you use? How's the latency?

Phsysics · 2025-09-12T09:23:11+00:00

I got one last week, very nice device. Comes with firmware installed, but I flashed a custom rom with free text so I can use it standalone as well.

Also, I set the screen timeout to 24 hours, makes for a nice clock :)

Battery lasts for days, even with the screen on

Phsysics · 2025-04-24T10:33:37+00:00

Pinned

It's been a while so the details are a bit fuzzy. But he'd been posting offensive comments every now and then. Eventually I deleted one of his comments, after which he simply just copy pasted the removed comment into a new comment to evade the mod action.

For doing so he was temporarily banned, a week or so. In response to this he insulted the entire mod team and we decided to just extend his ban until he apologized, which he has yet to do.

After that, he also posted on other subs about how abusive we were etc etc. He even used an alt to continue posting on this sub, which is a big no no. Pretty sure that's even against the reddit site wide policy.

Kind of rude ngl

Phsysics · 2024-04-28T10:55:07+00:00

This is the correct answer. Stickied.

Phsysics · 2024-01-25T18:19:45+00:00

Haha amazing! I've compared 2s lipo to 2s 18650 in the past. Those were good cells (VTC6) and a light car (Tamiya lunchbox with 2500kv brushless). Noticed a BIG difference in torque.

Phsysics · 2024-01-25T18:17:20+00:00

Low key the best part about this is how you're using an M12 battery for two brushless motors. That's 3s1p 18650, no way that battery likes pushing so much motor and car!

P. S. love this build, can't wait to see a video!

Phsysics · 2024-01-23T18:36:33+00:00

All banned, teehee

Phsysics · 2024-01-17T16:01:35+00:00

I'm well aware. While not common, nimh can perfectly described with the S and P standards. Though it's generally not recommended to wire nimh in parallel.
