    Can a Fenix 21700 battery with USB charger be used as a power bank?

    I couldn't find anything in their site. :( I've had a TS2 from Thrunite, and it works just like you are describing. However I think you can only charge it via the usb-c port. It's out of stock right now, but other vendors might have it.

    I'm building a new TITANIUM flashlight, I'd love your feedback!

    @ExceedDesigns Definitely interested! I have a few questions though for the 18650 version. How strongly is the clip attached to the body, and how easy would it be to get bent if pried out accidentally? I would be carrying this on the outside of my belt via the clip, and I'm sure it might get...

    Emitter Swap Gone Wrong.

    Wow, thanks guys! I never thought about using an iron, that seems like a much better idea than a torch or heat gun.

    Emitter Swap Gone Wrong.

    I recently got a replacement TC15 with a cool white XHP35.2 in it, so I tried to swap out the emitter. I had done 2 sst20 swaps before, so I was feeling pretty confident. First off, I attemped to swap the emitter to this 5000K XHP35.2 I tried to heat the mcpcb with my solder gun on the bottom...

    Fully Compressed Spring is an issue?

    Yeah, I thought about putting the spring at the front, except there's no good way to attach it that I know of. As far as the cushion idea goes, having a single spring on the front or back would only stop the battery from slamming one way, so it's 50/50 if it would do anything, right? The...

    Fully Compressed Spring is an issue?

    I figured out that one of my magnets fits perfectly inside my TC15 tailcap, inside the recess where the spring would go. I really like this idea, except the spring now sits on top of the magnet, and it's almost fully compressed when I put my cell in it. Is this an issue for the cell? In theory...

    Short EDC pens?

    Olight O'Pen Mini? I havn't purchased one, but they seem decent enough. The only con I see is the customized refill.

    Help with multi-cell headlamp

    @alpg88 I just realized that I said in series when referring to the cell amperage. Those are actually parallel, duh! Sorry about that. @Dave_H Yup, more cells are on the list! Just waiting for this money thing to work out. :broke: Thanks for the help guys, Mark

    Help with multi-cell headlamp

    Hey, I have 2 TH30 headlamps that I am wiring together with an external battery pack. The design is really simple, and I can easily convert the lights back to their original state. I have the lights running off one cell right now, but I plan on running them on three 18650s in parallel. I've...

    Power multiple 18650 lights from car battery.

    Hey, I want to run 2 Convoy s2s off my car battery. What would be the simplest way to do this? I don't mind hooking them up to the battery directly (12V) or powering them from the cig lighter (5V). If I wired the lights straight from the cig lighter, would the 0.8V increase from 4.2 V be too...

    Battery Protection Circuit Gone Bad?

    @aznsx That's good news, I think I'll get one before they're gone! I'm guessing you just use a spacer for 14500s right? The one in the link also says it covers 21700s. Yep, all my other cells (protected and unprotected) work in it just fine. It's just the one trouble cell. It's had a hard...

    Battery Protection Circuit Gone Bad?

    Here's a bit more info. I have 3 TH30 Headlamps and a TC15 that all came with IMR18650s. I also have a thrunite PB with a regular 18650 in it. The IMR cells are rated at 15 Amps and the reg cell at 10 Amps. I've been using the reg 18650 in my lights because I needed a backup and it worked...

    ---Immediately Accessible---

    I carry a leatherman on my belt at 4 o'clock position, so my TC15 goes right behind it. I just slide the clip onto my belt, and I can instantly deploy it that way. I've never really had issues with it coming off. I also carry a backup 18650 and a nitecore tiki IWB at 8 o'clock position. They...

    Battery Protection Circuit Gone Bad?

    That sums up exactly what is happening to my cells. I don't know what trips them though. The cells don't consistantly trip. Sometimes they work like normal, and sometimes not. I need to be able to rely on them, and this makes it quite frusterating. Normally, I notice the cells are tripped when...

    Battery Protection Circuit Gone Bad?

    I just did that. When the battery is "sleeping", I get a reading of 0.01V from it. Once I wake it up, I get 4.19V.

    Battery Protection Circuit Gone Bad?

    Hey, I have several 18650s that go into a "dormant" state and I have to wake them up if I want to use them. The batteries are thrunite, but I think they're rewrapped samsung 30Qs. The lights I run the batteries in are thrunite as well, and they have built-in charging ports. The batteries came...
