Hello again guys and gals. BlueSwordM here. So, I've noticed something interesting here. Over on BLF, a flashlight forum, I've decided to start on the journey of making a product in a domain from which I have a lot of experience in. In this case, it's flashlights,batteries, and chargers. So...

Sorry to bother you guys, but is there a reason I can't edit my posts after a certain time anymore?

So, as part of my removable battery pack project, I need some parts. I found my high current springs, I have a 3D printer, and wiring of course. To connect the cells in parallel and in series, I need some nickel strips. The problem being that I'm weary of most sellers on eBay selling pure...

So, guys, do you know Eric Lundren? He's a good friend of Jehu Garcia, which together, they made the longest distance electric car on the planet. Now, he is a recycler at heart. He helped recycle 10s of thousands of PCs, preventing them from going to trash And since companies, especially...

So, today, I looked at my subscription feed, and I saw Jehu's video: And apparently, he was banned from live streaming to Youtube from a copyright strike by listening bots to a private video. I would advise supporting Jehu Garcia by going to the Twitch link to watch his livestreams: Also...

Now, as you might know, there are 18650 flashlights floating around on the internet. If you look around on sites like most of eBay and Aliexpress, quite a bit of them have bogus brightness ratings(exaggerated lumens), have poor efficiency, bad user interface, and bad color rendition and color...

Good afternoon everybody. A while back, I tried to open a Dyson battery pack, but it was to no avail. Today, I threw the battery pack in rage on the ground, and it actually broke one the snaps, and it was quite easy. And to my surprise, I didn't get high drain 18650s, but I actually GOT...

Hey guys. BlueSword again. So, you guys remember the 1$ per cell video that jehu put out a while back? Well, since that day, I wished to be able to buy these new cells, but alas, they couldn't ship to Canada. However, today, I discovered that there's finally an option to do this! So for any...

Hi guys. BlueSwordM again, I know. So, when I went to the Home Depot to ask if I could take batteries, they of course, let me, and I found 4 Dyson Battery packs. According to their specifications, they had 6x2800mAh high drain batteries, and they were 20A each! So an excellent find, a really...

BlueSwordM here. After watching one of Jehugarcia's videos, I looked at the comment section, and I found someone talking about cell level laser fusing being employed by an Austrian company, along with other techniques like immersing the cells inside of a non conductive liquid, to get 18650/2170...

Hi guys. So I have a problem. While charging one of my red Sanyo 18650s, I noticed some bubbling noise from it, and noticed a small tear. In a panic, I took it out and I felt a nice oily scent in the air, and put it in sand. Is it completely dead? And what might have been the source of the...

Yo. I'm here. I've bought tons of 18650 stuff on Ebay lately, and here's my list for now Also, I know the BMS really isnt necessary, but I like over discharge protection, just in case. And ask me why I bought this and that if you want. Is there anything I should add to it?

Hi everybody. BlueSwordM again. So this might be important. Is there a way you could implement HTTPS in the site? Because every time I log in, there's a popup dialog telling me that the connection isn't secure. Thinking about it a bit more, it would be very important to implement HTTPS just for...

BlueSwordM here. I've got a question here for you folks here. So I'll be beginning my portable laptop battery project, and I'm currently tackling the charging situation. I'll be using a 3S Balance BMS Charger from a local shop since it's pretty cheap for 2, especially for a local shop, also...

Hi everybody! This is BlueSwordM here. This isn't my first time on here, but it's my first time posting. I know quite a bit about PCs and electronics in general, so I'm really interesting in learning even more about lithium-ion batteries and how to use them in a smart and efficient way. I don't...
