Wurkkos TS10 excessive battery drain

Anyone else seeing this with their TS10’s? I know a lot of people on here have them.

Had mine a few weeks now. Went to use it last night, I charged it last week. And it was so flat it couldn’t maintain any sort of brightness. Checked this morning and its down to 2.x volts!!

All it has done is sat with a fully charged battery for 5-7 days.

High aux will drain the battery in 3 days. Low aux will run for several months.

In the earlier batch there was no low voltage protection for the aux LEDs. Recent batches have LVP that turn everything off below ~2.7 V

If above 2.5V, that confirms the LVP works :beer:
Were Aux on High?

agree!

No problem on Low Aux.

I have had A TS10 w red aux on low, sitting in my backpack unused, for the last 3 weeks. I just checked, and the battery is still over 4V

Yes on High Aux, the battery will be depleted in a few days.

If using High Aux, best to check battery voltage daily.

fwiw, the blue and green Aux, on Low, are visible during the day. Red and Orange on Low are much dimmer, and can only be seen at night.

You did not mention, are you using the AUX lights? What color? What level?
As others have said the AUX lights can suck a battery down pretty fast if on high. Now if you are not using them at all, maybe there is some other kind of problem.

BTW, I charged the black one in my pocket 12 days ago. I use it daily for short periods. I have manual memory set to6/150. Occasionally I run it up to maybe 50/150 for short periods.
I just did the three click check. It showed 4.1 Volts. Just for reference.

I suspected the Aux LEDs……

However I have been running the light as supplied and in the default configuration.

If I was being picky I’d say it is poor design to let a light go out of the door that self drains in a few days in its default mode.

Aux are orange.

There is also a huge discrepancy between High and Low on the Aux lights (but I dare not site it as yet another Anduril shortfall :smiley: :person_facepalming: )

Having recharged the battery this morning. I have also changed the Aux to low on unlocked and off completely on locked.

In Wurkkos’ defense, the light was designed as an enthusiasts light. I am sure the rationale is that people buying the light would configure it to their liking immediately. While hopefully understanding the tradeoffs.
For instance, I disabled the AUX lights as soon as I put a battery into it. (but in my use case having AUX lights is a waste of money and manufacturing resources). Though I do get that it is a big marketing factor. Apparently there are many who favor bling over utility. Which is fine, just not my thing.

The “high” level of the AUX lights is a design/hardware “feature”. Not Andruil. That one you can actually blame on Wurkkos.

agree, factory should ship w default Aux on Low…
And imo ceiling in simple mode should be changed to 110/150, not the presently set 150/150… but this default is not limited to the TS10… it is just one of the User Configurable settings, that I change for myself.

congrats on changing the Aux to low and off
Aint Anduril Fun? lol

fwiw I also lower the memorized output,
by default it is about 100 lumens,
I change it to about 10 lumens…

I use 10C from On in Advanced, to save current brightness. The light will still also use the 10 minute Last Mode Memory that is a factory default.

Unfortunately it’s a hardware (and therefore driver design) issue that Anduril can’t really correct for. We’re kind of lucky anduril even has the “low mode” hack which uses the MCU’s resistor in series with the stock resistance (as I understand it).

I was surprised to check the battery on mine and find that it was at 1.56 volts, after having been drained by the aux lights. I bought a new one that was supposed to be fixed and it has the same issue. I turned the aux lights down and now I just need to disable turbo so I don’t fry the emitters….This light definitely curbed my Wurkkos enthusiasm a little.

Approx. how much bright are Orange Aux on both levels?

High: very bright
Low: not bright at all

Low you can’t really see in daylight and even in the dark would only help you locate the light if you are a few feet away.

High is brighter than the lowest output on the main LEDs and despite a bit of a funky beam profile works as a sort of moonlight.

Not sure if this is hardware controlled. I’d have thought more software on current and percentage of current.

If this is true, I wonder if there is a resistor in series with the Aux LEDs even in high mode. If so, one COULD mod the driver and change the value to something higher, so that perhaps a month of AUX battery on high mode is attainable and the AUX LEDs do something more than barely help to find the light in the dark.

I’ve got no complaint really on low mode, just wonder what is the art of “possible”. My red aux LEDs on low are very easy to see across the room in the dark with my TS10 pointing at the ceiling on the nightstand.

I like the Red Aux on Low for nightstand use. A couple of people have been able to alter the High Aux with a resistor.

Here is one mention:

Nice!

Here is one of Adair21’s ads:

Wurkkos TS10 - $55 shipped
battery included
choice of E21A emitters
resistor mod to lower aux brightness

:+1:

Thanks for that. I knew I had read about the resistor mod. Not only on the TS10, but others. Thanks for finding the good info.

you are very welcome :beer:

thank you for the encouraging words

Thanks for this lead jon_slider.

Hmm, I think I have the materials to make this change myself, but I’m not sure how easy/hard it is to access the other side of the driver board. Guessing I could get a reasonable guess at a resistor value if I saw the one used presently. Guessing its 10 ohm or less for a 3 day draining of a 4.2V battery. probably 50 - 100 ohm would do the trick. Guessing the internal resistor in the MCU is 1k ohm
