Convoy C8+ SST40 Firmware Question

Interesting

Anybody have one in their hands yet to confirm if direct drive or not on high? Thanks

A little surprised Simon hasn’t gifted one to one of you “reputable” (I.E Honest)
reviewers to check it out?.

Or has he???.

Basic C8+ with 26650 and side sw. with simple On/Off.
Puleeeeez. (Just for us lazy buggars out here hey.)

I bought 4 of these (Drivers only) from the convoy store and the first one I used in a C8 did not work as advertised. Mine has 2 modes. mode 1-L,M,H then mode 2- L,M,H and strobe. I have sent a message to Simon with no response. I can also add that it takes 5 half presses to switch modes. Thought maybe he sent the wrong drivers to me. Even went back to double check my order because I know there are 2 versions of this driver. Weird.

Does anybody have an idea what other firmwares will work with that driver?

Had one of these arrive yesterday.

The UI is a bit strange. First full click took me to what appeared to be full power. Two half clicks took it down to a lower level. Nothing too bad there.

Five half clicks got me to the bit where it ramps through the power levels. It’s a bit odd and needs getting used to.

As usual I can’t criticise the quality, everything is spot on.

On high I’m getting 6.9A at the tail from a Samsung 30Q which seems pretty good, and it’s bright, considerably brighter than my C8 with XPL HI and Fet.

I might get a BLF A6 driver from Banggood and drop that into it assuming the SST-40 won’t burn out using a Fet.(?) The UI would be a bit more user friendly.

I reckon that 6.9 amps should be giving me over 2000 lumens. Pretty good for a stock C8. I might even leave the current driver in place, I like going straight to full power.

Is the ramping level stored in the first and second mode, or is the first mode always high? The diagram is confusing.

I am yet to finish a C8S build with one of these you are speaking of. Despite weird the UI features two ramping modes, 1st and 2nd. The third is the multiple selectable functions one. I plan on setting it as follows:

  1. Single tap: ramping set somewhere in the middle, for a nice and practical amount of output versus current consumption.
  2. Double tap: ramping set at 100%.
  3. Triple tap: 1%.

So can this driver be reflashed ?

Can these C8+ be fitted with an ON/OFF 100% sw.
Nothing else?.
Or. As I have in a SolarStorm SC02. (18650 cell)
Side sw.
1 and hold. is ramping, Set where you like and it’ll stay there. with a single click… to 60%ish.

Then it’s.
1 click for that setting.
second click is 100%.
The perfect switch for a no nonsense torch.

Get rid of all the other settings, OR don’t have,
IN THAT torch.
Just have fancy switches in multiple others
as we all do.
And I’m just a starter novice at collecting torches.

I haven’t checked this personally, but from the diagram it would appear to be the case.

Just got my driver for my s2+ triple xpl hi. Loved the driver so far

the first 2 mode is ramp programmable.
while the 3rd mode is a special group

but there is no memory in the mode cycle so it always go mode 1 mode 2 mode 3

you can set your first and second mode brightness to your liking by 5 taps when you’re on the mode.
while the 3rd group you can only choose a few options listed on the mode lists

Just tried a brand new, 30Q and got 7.1A at the tail. This could end up being my favourite C8

My C8+ SST40 with ramping driver arrived a little while ago and I’m very pleased with this light. Firmware seemed confusing according to the diagram but in real life it’s a fantastic firmware.

I measured 5.9A on 100% brightness with an LG HG4

It seems the reverse clicky switch supplied is the same used in other Convoy models (S2, S2+ etc). What are people’s opinions/experiences on the lifetime of this switch with 6 amps going across it? I couldn’t find any info on what the switch is rated for.

Omten 1288 switches eggmang, also known as “small Omten”. They're rated for 1.5A or so. I have some in service doing nice at up to 10A. When going really high current with them it is advisable to bypass the spring attached to them, namely if in direct contact. Their housing is made with a soft plastic which readily deforms with heat, this means you have to be pretty quick and careful when soldering over their terminals. Every time I solder one I verify test its resistance with my precision power supply and multimeter, a brand new or undamaged unit features 4mΩ of resistance or very little more.

I really find no good reason to make a switch with such a @#$% plastic. Pity.

:-)

Thanks Barkuti :+1:

From Convoy the driver and tailcap springs came with a bypass wire already soldered which was nice. I tested one of these springs once at 16 amps without the bypass wire and the spring itself got so hot that it could burn skin :disappointed:

I am considering removing the switch and short circuiting it so that the light turns on/off by tightening/loosening the tail cap. This should give even less resistance :smiley: Is this a common practice among modders?

I also found these today, this will be useful for the driver end as it should have less resistance than the spring and bypass wire; (at 6 - 8 amps these small improvements should make a difference in light output) :+1: ;

Wouldn’t the 21700 version be the m21a? There’s a groupbuy thread on it.

Does anybody have any review/opinion on the new(ish) Convoy 4-mode driver with thermal regulation ?

Is it legit thermal regulation, or just big dumb stepdowns when sensor goes over 55C? Does it work well ?

This is what I’ve written out for my customers so it’s easy to understand
