【convoy】H4 and B35AM options are updated

This is a big step. Kudos for Simon for implementing it. With the 10 times tap I keep entering the config mode unintentionally which is very frustrating. With this driver that won’t happen anymore.

@Simon, when will the 5A 12 group driver receive this update?

It’s already here. 17mm, 20mm, 22mm, boost 20mm, boost 22mm and 8A already have 20 clicks. I just don’t know if the boost for xhp70 is with the new soft.

I trimmed retaining rings to fit. This is also tedious, but I didn’t even want to go down the road of heat up the entire pill.

I thought I only had to do this because I used QLite drivers. Does the Convoy 8 x 7135 driver interfere with the retaining ring, too?

Is there any way to disable mode memory on T2 (latest version)?

The convoy 7135x8 is pretty much the exact same driver with different software and it’s red instead of green.

Probably not. I wish it had a programmable driver. At least memory on/off.

It’s possible. Reylight has a AA/14500 driver with programmable modes and memory on/off.

The 5A 12 group driver has been updated several months ago.

AA/14500 driver can use 12 groups program, but the cost will increase greatly. Because T2 did not sell much before, I did not consider producing this driver.

The T2 takes a 17mm driver, so you can replace it worst case.

My bad. The ui chart still mentions 10 clicks so I was confused.

Anyway, a big step. My S2+ with the 5A driver, E21A 4000K D220 quad led, 60dg tir and removed glass i currently my most used flashlight.

There seems to be some margin for error with the new drivers (like there was with the old drivers…)

I have 3 of the new 17mm 5A 12 group drivers. One of them acts strange. When programming the light the LED remains on but dim in between programming blinks, and seems to have a much higher lowest mode than the other two.

The other two drivers work as expected, the LED is off between programming blinks and the lowest mode is pretty low.

I ordered a few more to mess around with. I’ve used two of them to make S2+ triples.

Some 14500 cells (such as Shockli 1000mAh) don’t fit in the T2.

I’m OK with it at this price point :+1: .

Has the latest version been more successful? Would be nice to get it in the new S21A colours (specifically the green and orange) :innocent: .

Simon Mao, on my flashlight from the last order (convoy s2 + LH351D 5 Amperes), a shunt in the spring from the side of the button fell off, and this happened almost immediately, literally after 2-3 battery replacements. I don’t know how to do soldering and I don’t have a soldering iron!
The question is: what are the consequences?

It is possible that because the internal resistance becomes larger, the low-voltage protection will be entered in advance. I have a switch with a copper spring, which can be sent to you for replacement.

Lumintop 14500 fits perfect in T2 but for me not worth use it because the difference of power with AA it’s very small.

Well, that’s a shame. I have some button top 1000mah Vapcells I was hoping to use with the T2 I just ordered. Might need to look into what is preventing the fit.
On another note, I’m looking forward to my M21C-U XHP70.2 and another simple S2+ with a Dogfart and the new FET driver from the same order.

I wish we had figures for the new XHP35 HI offering in the M21C though, I would have maybe bought another if there were candela ratings available.

this is great news, I will write to you in the store! Many thanks! :+1:

So would it be correct to say that it appears this is a driver issue/inconsistency rather than the LED type the driver is used on?

I've had a few different Convoy lights that use this 12-mode (Biscotti clone, not the original Biscotti) driver, and also noted that for some lights, when doing voltage check:
- on some flashlights, the main LED stays on at a dim mode, while it "blinks (brighter)" out the voltage count
- on some flashlights, the main LED is off, while blinking the voltage count

(for comparison, on the original Biscotti, when doing "voltage check" mode, the main light is Off in between the "blinks" for voltage count)

The issue you mentioned might be related to the observation I noticed (main LED is dim, or main LED is Off in between blinks)

What is the difference between this:

version of M21B with XHP50.2?
OK, first one is 3V LED, but for second one, there is no info.

The first one uses XHP50.2 3V (FET driver), the second one uses XHP50.2 6V (boost driver).
