Simon, I received your new M3C today the one without a head spring. Spring tension on the 26800 with extension and the 26650 with the body tube only is mild to weak. On moon mode a mild tap will turn it off. Other modes it flickers. My quick fix so far is to remove the retaining ring. Press a P60 outer dropin spring into the hole along with the supplied tail spring. It fits very snug but a longer stronger tail spring is needed.

@Di_Joker

Yes, there is a similar problem with the S11 spring. I put a vertically switched flashlight on the table and it switches the mode. :person_facepalming:

i can send the 26mm plates if you need it

There is a possibility that this is a temporary solution to the problem. The spring will squeeze again over time and everything will repeat itself. I think need a more powerful spring or a double spring for flashlights with heavy 26650 batteries.

spring can soldered on the the 26mm plate, The area used for welding the spring on the driver is too small, and I cannot find a suitable spring that can withstand large currents.

[PiercingTheDarkness]

Maybe talk to BlueSwordM about his high current springs, together they can handle 21A. Maybe they will fit

Found on r/flashlights, credit: u/N0b0dyfromsomewhere. He says “A new SBT90.2 flashlight model, 81mm head, using 26800 battery
from Simon’s FB profile”

Can Simon please confirm?

Yes, it’s a sample ,but the driver is not good ,
it’s a FET driver, The manufacturer claims that the maximum output can reach 25A, but when I measured it was only 19.2A

Looks good, that’s your biggest reflector yet. Any chance of a M3 or L2 size head for us pocket rocket people?

[JaredM]

L2 pocket rocket? Haha

Those are some extra Texan pockets

[Souldrop]

Any ETA on the IR lights? Thanks!

[will34]

Love the design on the new 26800 light! Finally a proper SBT90.2 mid size thrower with adequate cooling. I’ll sure order one when the driver and spring issue gets sorted out. Just squeeze in a bigger FET and worst case scenario use solid brass +ive contact and 18awg bypassed rear spring.

Will it be called the L5?

Uh, what I mean is that the positive electrode of the battery and the driver are not in contact with the spring

The driver now only has a stud. Prefer springs on both ends to allow travel under shock without loss of contact.

Thank you very much

[JaredM]

Simon. Please consider making some sort of shock dampener for the positive contact on drivers using the brass stud. This would ideally be a low durometer rubber or high density foam that prevents the positive end of the cell from being dented from impact. A plastic ‘cap’ that surrounds the stud and only let’s it protrude a mm or less would work too

Like a gun-light, I’d imagine.

Recoil would be Hell on a driver…

What a beauty in polished silver/raw!

Simon, do you plan to make these in 2 x 26800 with one piece battery tube (no adapters)? Then you could use your L7 driver. Please do and I will buy.

There is a very simple way, you can use silicone o-ring of appropriate size for the thread,
For example, 26650 battery, you can put some 26mm O-ring on the positive pole

This one has charging port ,
If it is designed according to the L7 style, the charging port will be removed
