Worst case, the battery might short and explode. It is probably more realistic that the driver would burn up and the circuit may fall apart before the cell gets a chance to explode. I posted a video last year where the driver started smoking and burnt itself due to the battery being inserted backwards. I tested reverse polarity protection with a protected cell at the start of this video, this just caused the protected cell to cut-out temporarily.

@@TorchHacker ah yes that’s right. You’re a braver man than me testing with the unprotected battery haha

Heya, there's a Buy/Sell/Trade thread on r/flashlight here: www.reddit.com/r/flashlight/comments/1ftf7y8/bst_october_2024_buy_sell_trade_thread/

I haven't really fixed it. I smashed the glass on the sidelight. I think there might be a design flaw or connectivity issue where the Ground side of a battery is not making contact with the Ground terminal of the Driver. The connection for Ground appears to go via the tail spring, aluminum case, up toward the head, through the MCPCB, and back into the driver.

​@@TorchHacker Yes, you're right, this, a design flaw. There was a bad contact of the LED pad with the housing, the problem was in the fastening of one screw, tinned the copper pad around the screw hole and the flashlight worked. But when reassembled, the lens presses on the LED and the pad comes loose, works, but shock/shock due to the one way locking(screw head) can break the contact. And heating the glass was very difficult, ended up pouring alcohol on it and removing it))

I haven't used the P50B. The P45B is good.

Yes. The bigger Customizable button can be fully pressed to use Strobe. But you need to configure the button to be Strobe. By default it is LUMIN SHIELD mode (brightest). To configure it to be Strobe, you simply fully press the Customizable button and then press the Power button. The same process can be done to switch back to LUMIN SHIELD.

@@TorchHackerAfter you set the big button to be strobe, it is the default for that button until you change it. I have the small button set to 15 lumins at half press (momentary) and 100 lumins at full click lock press.

@@xthyagox1 There's a review of the Mateminco MT70 Mini on budget light forum. I prefer the IF30 but I haven't used the MT70 Mini.

@@TorchHacker Can I provide the purchase link for the Molicel P42A please? AliExpress

@@TorchHacker Can I provide the purchase link for the Molicel P42A please? AliExpress?

@@xthyagox1 I bought some from the user Vapcell Dennis on budgetlightforum by sending him a personal message and paying via PayPal. Vapcell has a store on AliExpress but messaging him directly on BLF might be better.

@@sergii_rodin I'll measure the height of the NU27 headband and check to see if it can run off an external battery. I posted some runtime graphs on my blog.

@@sergii_rodin The height of the headband can gap is about 25.6mm. I was able to power it directly off a USB-C power supply.

@TorchHacker Thanks for the answer, my friend! And what external power supply did you test? I was a little worried that the power supply from Nitecore has a type-C with a hook (for NU40, NU43, NU50), but the NU27 does not have a hook for attachment ( And also the width of the head-band 32mm vs 26mm

@@sergii_rodin I used a USB-A to USB-C cable with a straight plug. The USB-A end was connected to a USB-C QC port in a PinePower Desktop power supply.

@@sergii_rodin The PinePower Desktop supply showed a current being drawn while using the headlamp on Turbo.

I don't think it supports 1.5V Li-ion. It doesn't detect the cell when I insert it. It can charge 3.7V Li-ion (4.2V full). I haven't had any heat issues.

@@TorchHacker Thank you!

No, just AAA/AA/10440/14500 sized cells. The C4 Evo supports some 21700 but it's still better suited to AAA/AA. XTAR VC8S/VC4SL, Vapcell S4+ are some good alternatives that fit 21700.

That's the best part the scratches give character

I can't see any storage option. The user manual mentions the storage voltages but there does not appear to be a storage mode. There is Charge, Discharge, Activation, Analysis. The C4 Evo might be better for that use case.

I'm not sure what the battery lifetime would be in RC cars. The N16 supports 1.2V NiMH AA/AAA, 3.7V Li-ion 14500/10440 (4.2V full). It has these functions: Charge, Discharge, Activation, Analysis (capacity). The charge and discharge current can be set (you might get a slightly longer battery life in terms of recharging by using a lower charge current).

@@TorchHacker awesome thanks for the numbers it will help with calculating a bit out im looking at two different styles of use so i really like the informative approach regardless so this really does help thank you

I think it's about AU$179 but there might be a sale. It has just been launched.

@@TorchHacker yeah looks great man!

@@loner1512 I actually prefer LADDA AA 2450mAh from IKEA. They're almost the same (same factory?) as the eneloop pro AA.

It's being held by a SmallRig clamp and arm.

@@TorchHacker Nice😎🔦

A strike bezel would be awesome 😂

It's hitting 8,000 lumens momentarily 😁

The side switch will work with two 21700 cells. You might need some spacers if the cells are flat top so that they can connect properly. The tail switch will not work because the signal for the tail switch goes via the Acebeam battery pack.

I've still got a bunch of micro USB cables for CB radios and gadgets 😛

@@TorchHacker but, it´s 2024... Even USB-C is 7 or 8 years old now... just.. why?! But well, Logitech is as ridicoulus as this and keeps building Keyboards with MicroUSB (G915) ...

@@StrikingTill It's a hard choice. The beams are almost the same. I like the design and driver of the Bow more. My only gripe with the Bow is that High steps down quickly and I haven't figured out how to take the LEP module out.The L2 is fussy when it comes to 14500 batteries but it has a nice design too. I'd probably choose L2 in a different metal (copper etc).

I'll post a comparison

@TorchHacker I noticed that as well; reading your review. That's the only downside I see compared to the L2 . It can literally hold 4x the lumens @ 10 minutes. I wish the Bow had come in at least aluminum. It would be an instant buy. An aluminum Bow would probably have higher sustained lumens as well compared to these titanium versions. Thanks for you time. Looking forward to the comparison 👌🏼.

A few slight adjustments could improve the speed 🙂

I prefer the floody beam caused by the frosted lens. It allows me to work on stuff close up (e.g. clean a car at night) without creating an intense hot spot.

@@TorchHacker Ahh i see. How about in outdoor situations? Is it still using as a walking light or is the beam too diffused for that purpose

@@wesleysong1987 It's ok on a high mode for walking outdoors. If it's really dark then a medium mode is ok when walking slowly.

@@wesleysong1987 I just used it earlier this evening while taking beamshot photos of a LEP torch being released tomorrow.

@@TorchHacker what’s the sustained output?
