New Convoy T2 - Remove mode memory?

You can also swap in a 17mm driver with whatever ui you prefer.

I was hoping for some assistance locating that, I’ll have to dig into it once I receive the light. It seems to have cleared customs and has been sitting at a distribution site for 3 weeks now.

I keep forgetting this takes a 17mm driver…

Being an electronic novice, I’d also love some more detailed instructions or a picture with the specific spot circled. Mode memory really saps the enjoyment for me.

In the Convoy thread a few of us were trying to talk Simon into going through with his plan to offer the AA/14500 driver in the T2 with the programmable 12 group firmware. That would allow different mode groups and more importantly allow memory to be turned on and off. He thought the T2 wasn’t popular enough, but it seems like it’s catching on lately.

Let him know that I’d order a few. Getting Biscotti, high CRI, and some nice tint choices would be a real win for Eneloop users. I know a few people IRL who’d be interested too.

If it is AA compatible with Biscotti (or clone), it will be the flashlight of I choice to give as a gift to replace the discontinued SF10.

I wish a few of the mode groups in Biscotti were a little different (specifically I’d like a 0.1–1–10–100 group), but and I’m about to swap a Convoy 7135 Biscotti driver into my T2 anyway. That’ll get rid of Ni-MH support, but my other problem with the T2 is that none of the AA Ni-MH batteries I have actually fit, since the tube is maybe half a mm too narrow. Fix those two things, and it would be a chunky 14500 light but a decent one.

I have a Biscotti driver on mine for a while and it works well! Unlike yours, I guess mine takes all the Ni-MH cells I have both in length and diameter. Maybe it was a different batch you got :zipper_mouth_face:

I don’t think the pencil trick works on all drivers, as it should depend how they set mode memory.

If it is based on a capacitor, I would expect it to be a capacitor that has a trace leading either directly to or through a resistor to a pin on the microcontroller. However, I can’t tell from the picture on Convoy’s store which of the tan capacitors it would be. I would speculate either the one on the back side that is between two small resistors, or one of the two on the top side that is between the red wire and the microcontroller.

Since this takes a 17mm driver, it occurred to me it is possible to swap in the 17mm SST-40 driver, do a spring bypass, and with a high drain 14500, have a remarkably high output light for the size: 5A even with a high CRI LH351D should be over 1000 lumens.

I have a T2 with a swapped driver and it does put out a lot of light, but the real attraction of the T2 for me is NiMh compatibility. So if Simon improves his boost driver for the T2, option for no memory is my main wish, I prefer that to anybof the lineair drivers.

I’ve held off on the T2 specifically because of the mode memory. If Simon ditched that I bet he’d sell a lot more of these.

I bought one of the early ones with the blinky driver, and swapped in a 17DDM FET+1 driver into it with a CRI90 3000k XP-L 2 HD. It’s…. silly. I’m actually on my second LED, cause I fried the first one purple pushing the thermal limit :smiley:

Sorry to hear about the NiMH issues. In addition to the nice balance of size, power, and run-times with AA, using Eneloops is a major draw for me.

Yeah, Biscotti isn't perfect. The twelve groups don't cover every want. It's just that they cover a whole lot of wants while simultaneously avoiding major deal-breakers. For me, group ten (1% - 10% - 35% - 100%) with no memory is close enough for everyday use. While I rarely deviate from this group, I like that I can change to a group with moonlight for camping or very long periods without access to electricity. I find tremendous value in both having all of those choices and being able to segregate just a few for a nice, simple, day-to-day mode order.

Given that I can get this freedom on reasonably priced tail-clickies with lots of emitter options has really helped Convoy to become my go-to for flashlight shopping. I like Sofirn but mostly for the AAA lights. Electronic switches and Anduril aren't my thing, except for maybe the rare circumstance in which I want candle flicker on an off-timer.

I bought the T2 driver in put it into a modified flashlight. I just use a Li-ion battery in it and the output is impressive!

It’s great that it can take both AA and 14500 batteries, but like others, I don’t like the memory mode. It seems that if given a choice to program memory mode or not, no memory mode would be the better. But maybe that’s not possible with the driver?

These would be the capacitors to do the pencil trick on.

I’ve had a T2 in 3500K sitting in my cart for months now. I’ve held off because of mode memory. I’ve kept it in my cart as a reminder to buy in case it’s offered without memory.

Has anybody tested this yet? My driver is currently soldered in a p60 pill and I don’t really feel like trying to wick all that solder out if its not going to work.

I just tried, but no luck unfortunately. Bummer!

I ordered 17mm biscotti version… I believe it have memory off function. but 5A will be too much for 10W led :frowning:

Just select Mode group 8 (max. 2.5A). What LED yours T2 is using?

Actually i have S2+ xt-e 3000k and S21A CSLPM1

Going to upgrade the S2+ with CULNM1 with that 17mm biscotti.

Yess… i did mode 7 on my S21A :wink:
