Convoy L6... XHP70 Beast!

I’ve got a weird user interface programmed into my FX30 driver. It functions kind of like the new S70s light.

The rear switch only activates standby. No light from the xhp70.

Here’s my video link again showing my L6 with this new UI.

I looked over a spare fx30 driver to find a spot that might have positive power to it, but I think the white silicone covers it.

I even looked for space to drill a tiny hole to run a wire from the spring side for positive power, but this board is completely covered with components. Ahh!

I think I’m gonna have to rig up battery power to it and probe around to see if I can find a power source. I have no idea where to probe as I don’t have much knowledge about driver design.

Maybe I’ll scrape away the silicone as a last resort.

Can anyone tell me what the big metal box is?

I may have found a source of positive power.

I got a good reading here, but this was on my old Convoy version which turns on the emitter when the rear switch is turned on. Hopefully my Kaidomain driver has power here when its in standby.

The switch looks like it uses an 1206 sized led and the 2 bare wire pads on back go to one of each led pad. The other led pads seem to link together and connect to the blue wire. I’m guessing the blue wire is a ground?

I could probably add a floating resistor into the wire from that positive source to either the purple or yellow pad on the back of the switch.

It seems 1206 leds vary from 2 to 3 volts depending on color. Does anyone know what resistor value I should use to drop the 8v down to 2 or 3?

Think of the resistor as limiting the current. So if you want 5-10mA to the 1206 LED, then a resistance of 500 to 1000 ohms in series with the LED should get you close.

Yeah, I can probably buy a variety pack of resistors from radio shack and try them out.

The leds, on the other hand, I’m gonna have to order.

Any news on the short tube? Still hasn’t appeared in the Convoy store.

Jason, I have a slew of those tiny LED’s for the lighted tail switches in like 8 colors, will those work for you?

Sure, I don’t know what color I want though. Could you spare 2 of each color so I could try them out?

Simon sent me some clear side switch covers, but they are still a week or so away.

Has no one done a lighted switch on the L6? Even with the stock driver, it’s kinda hard to find the side switch to change levels.

I remember talk of Simon adding lighted side switches to the L6 as part of a battery indicator, but haven’t heard any more about it.

Frankly, I haven’t heard anyone being able to reprogram the FX30, except Simon. I really like this new UI that I have except for the press and hold to turn off.

I think the rear switch going into standby and lighting the side switch would be great. Then one click to turn on, press and hold to cycle through the levels and one click to turn off would be great. Have memory even after the rear switch is off.

Then use a double click to get instant turbo. Triple click for strobe. Or just a double click for strobe. Either way, no big deal. Now that would be sweet. :slight_smile:

is the 7-7,5 amps measured from the tail cap?
i added the same r100, but only measured 5amps with 26650 keeppower batteries, need more current :slight_smile:

Same here, I added an R110, stayed under 5A as well. (my L6 was from Gearbest), could it be that several versions of the driver are around?

Welcome to BLF, solRNY !

Yes, they measure at tail cap. Adding a wire to the negative emitter lead and using a clamp meter should give more accurate readings. I haven’t tried this though. No clamp meter. :slight_smile:

All L6 use the FX30 driver. Simon’s version has the uniquely modified UI with wider spaced modes, no stepdown and 2 R082 resistors. So if you have that, then you have Simon’s version.

Folks have said that adding a 3rd very low resistor, like under R100 will basically make the driver go all out and it’s basic design is limited to 9 amps or so. Some folks have said their driver maxed out at less than that. Like 7.5 amps. I don’t know why it varies.

Stock L6 should get 5.25 amps at tail.

Back when I did my first resistor mod to my L6 I added an R082 and a ceiling bounce measurement went from 311 lumen to 344 lumen. It was a noticable bump in brightness.

Exactly , 7-7.5 amps at the tailcap with an R100 . Even with the R110 you should be in the 6.5+ amps range .

Stock is 5-5.5 amps .

Keep in mind it’s difficult to get good readings at the tail cap with a multimeter. You need thick, short leads.

My multimeter with skinny, long leads is not good at all at measuring tail cap loads. It was reading 3.8 stock and 4.1 after the mod. That’s not accurate, but I can still do relative comparisons.

On my second FX30 driver I just added a tiny wire over the sense resistor to make it go full blast. It seems to be holding up fine, but I have not measured to see if the lux improved. I did just now measure the tail cap amps.

Using my original protected KeepPower batteries.
Turbo/high = 4.35 amps
Med = 2.0 amps
Low = 0.5 amps

So using the wire over the sense resistors gave me roughly 0.25 more amps compared to the R082.

Using my new Liitokala batteries.
Turbo/high = 4.9 amps!
Med = 2.07 amps
Low = 0.5 amps

Now these liitokala batteries are giving a bigger jump in amps. Maybe it’s their less internal resistance?

I’ll try and get a clamp meter and remeasure for accurate numbers.

BTW, this new FX30 I’m using has 1.45 milliamps of current draw in standby mode. I don’t know if thats okay or excessive, but I keep the rear switch off when I’m not at work.

Even with a multimeter & 16awg short leads i wasn’t able to get correct readings .
I only use clamp meter now (uni-t ut210e) .

Hey, that’s not very expensive. I think I’ll pick one of these babies up. Thanks. :beer:

There is a coupon from m4dm4x too . :beer:

I can’t find it. I saw one from Freeme. Is that who you were thinking of?

The short tube is listed now. I’ll add the link to the L2/L6 modding thread and the OP here and in the L2 thread later with the additional details.

Hi Djozz, which batteries do you use? My L6 is from fasttech and with r100 and fresh liitokalas this at 7.1 amps + - greetings.

I will do another measurement, I use the same 5000mAh Liitokala’s.

Well, try sanyo ga, kill two liitokalas doing shortcut, a stupid mistake on my part :person_facepalming: , with fresh sanyo drain very fast, start above 7.3 amps and immediately start to go down so this battery is not enough for Feed the modified L6 but it serves as a sample, greetings !!
