Nope, you got it wrong. I want the driver without MCU (PIC). The IC is the SOT-23-5 chip which “convert” PWM to linear drive.

Yes, that’s exactly what I want :slight_smile:

Ok, I will check tonight after work.

Yep, I definitely read it wrong. :person_facepalming:

Did you maybe check it? I just bought one MR C8.2 host,looks interesting enough for extreme power.

What is currently the best 26650 cell for high discharge (25-40A)?

I wasn’t able to check last night, but I will definitely check today when I get home. As for batteries, I use Liitokala and Shockli. Here are tests of the cells:

I assume the PLB 55A cell, e.g. Keeppower 6.000mAh or Shockli 5.500mAh should be the best high drain cell for 26650 size.

I thought KP wasn’t a high drain cell.

Vapcell/Aspire/iJoy/Golisi 4200-4300
Shockli 5500

That table is great,only internal resistance is missing for complete information.

What is best reliable source (China or EU) for Vapcell/Aspire/iJoy/Golisi 4200-4300?

I think both Banggood and Gearbest sell Golisi though I have never ordered a 26650 from either site, only US vendors.

I saw that lion wholesale is having a clearance sale on the Aspire 26650 for $6.99 per cell for those of you who are in the US.

This one is the best 26650 for basically every application.

For maximum current the Samsung 30T (21700) might be a little bit better, but is has a much lower capacity.

Ok, I misunderstood I was thinking of the older KP batteries. So the KP 6,000 mah is the same as the Shockli 5,500 mah cells.

LEDIL ANNA-40-7-S 7x TIR Optics – Spot

What leds go with optic?

C8?

Spacer?

Ok, I checked the switch board and here are the measurements: thickness = 1.3mm, diameter 20.2mm . They are the same ones that Simon used to carry on his Convoy store with HGJ stamped on it. The host comes with the high amp forward switch that Simon sells on his store as well:

I don’t have any tools to measure the switch hole threads but I posted pics below. I’m not sure if that even helps. Let me know if you have any other questions about the tailswitch.

I got mine from 18650.uk. Out of stock at the moment and very expensive though. Nkon also has them.

edit: misread, you said 4200-4300… disregard my post

I have 34mm MCPCBs for 6x 3535 and 4040 LEDs that are compatible with ANNA optics and Convoy C8. I will offer assembled PCBs with LEDs I currently have in stock, LH351D 4000K 90CRI and Luxeon V 4000K 70CRI.I need to do basic tests and build few "demo" lights to see if everything is ok. I will have spacers too, but it's summer vacation season so there is little delay.
