WildTrail WT90 - SBT90.2 1800m+ throw 90mm 3x 21700 With Texas_Ace driver

Thank you TA, I will re-read everything and see where I stand. I like the idea of keeping the charging. But if solutions for the light have been worked towards, I will def weigh the overall benefit to the light.

Will removing charging address some parasitic drain and the glowing LED, or just the residual drains?

WildTrail sent me these pics to share with you. I was also given a short video clip that shows the deep heat fins of WT90. Texas_Ace, maybe you like to put them into the OP, too?

That’s beautiful…

It really is a beauty

I’m super excited for the group buy and everyone able to get one even though I’m not buying one (already have a silver).

Everyone’s gonna love this thing. It’s like a really pretty piston with a lightsaber coming out the top. It’s also got huge Art Deco swag with a bit of a retro museum-piece/trophy-vibe, let’s just say it’s an absolute classic.

So, i couldn't get any beam shots at the beach because of the flashlight paradox that happens at CT state parks where the sun goes down at 8:20pm, it gets DARK at 9pm, and the parks close at 8:30pm.. So these are from outside my house, distances measured with google maps. Unfortunately not a good amount of range, but WT90 looks like Daylight at 350 meters.

Now, zoomed in

now, zoomed in

and just for fun

This is my problem, state parks have the best access to range other than pulling over on the high way! lol

Oh wow, that would be Awesome! How would you limit to 9 amps? in the firmware with anduril 2?

This has to win flashlight of the year.

I love photos like this!

I remember I bought 2 Lumintop SD75 that featured inboard re-chargeability AND power bank functions, though it had a much simpler design as the carrier was the usual 3-cell carrier with the charging circuit situated at the bottom of the battery tube.

Both SD75s had horrendous parasitic drain that it ruined two sets of 18650s. Perhaps more design research is needed to mitigate this problem, at least for me.

Personally, I will have to wait for the WT90 to iron-out this parasitic problem before I dive for this light as I am really a fan for this light’s design, performance and powerbank versatility, but a phobia for lights that has parasitic drain issues.

i was saving $$ to buy the new Lumintop top SD90 like 2 weeks before TA dropped this group buy! I wished the head was larger on that light because it looks pretty awesome otherwise. While I was trying to dig for info on it because it was new, I found 5+ year old YouTube reviews of the SD75, which seemed like it's predecessor but with the xhp70.2 . I haven't seen much about the sd90 since the WT90 came out. Interesting lol (it is $40-$50 more than the WT90 with a 10mm smaller head, which I equate to less throw).

it gets my vote, with the Emisar DT8 at a close second. But regarding value/thermal design/aesthetic (IMO)/ and performance: the WT90 is unparalleled.

Both tests were started AFTER 12 Hours of Rest after being Fully charged.

After 4 days the original carrier dropped from 4.23V to 4.17V. A 0.06V loss.

Below is Toms modded carrier that he swapped with mine.

Started at 4.21V and after 4 days was 4.20V.ONLY lost 0.01v.A typical loss not associated with parasitic drain.

Conclusion…SUCCESS :+1:

Off to the dentist.

Ok, good to know!

Disabling the charging on the carrier should remove all parasitic drain from the carrier leaving only yhe normal parasitic drain from the driver itself which generally takes 2 years+ to drain a set of batteries.

Sadly I do not see the charging parasitic drain being fixed while keeping the charging working. This is why I don’t care for internal charging. It can be done but takes a lot of extra work to make it work properly.

Updated the OP

Thank you. My Google Drive links were unfortunately messed up by some update, so I had to restore some information, e.g. manuals. If you want to update the link to the manual once again, here’s the new link:

What is it about internal charging that causes parasitic drain?

The Charge circuit IC’s are simply not designed to have the low parasitic drain that we need. They are designed for items that are used regularly or need constant monitoring.

It can be made better but takes more expensive components and R&D that most flashlight manufactures are not even aware are necessary. Parasitic drain is something that manufactures seem to completely ignore for some reason. I have a few lights that from the factory would drain the cells in a few months.

A lot of moisture in the air and even more haze from the Canadian and West Coast USA fires.
