I've never seen an 18650 battery with a sleeve that is connected to the negative terminal. Most of them have an insulating jacket. It would be really dangerous to build them the way you are suggesting, because shorting them out would be nearly impossible to avoid
@@bytesizedengineering thanks for the reply, I understand what you are saying, what I was stating that technically what you stated was incorrect. The only difference between the negative at the bottom of the battery and the rest of the case is the wrapper. If you needed to attach to the case it wouldn’t make a difference electrically. As long as the attachment point was insulated from the possible there is no additional danger. High Temp Kapton tape is commonly used to reinsulate after a penetration of the sheathing you can also purchase the positive isolator and precut shrink wrap for 18650, 20700 and 21700 quite readily. Thanks for all the entertainment. Keep up all the amazing work.
I had an explanation for this in the video, but I cut it out to be brief. This is a prototype, and so I didn't add any BMS or charging circuits on the board. Maybe in the future I'll add that. For now, the two battery terminals are accessible on the top circuit board. I can temporarily solder a standard JST connector pigtail and use any lipo charger
3:42 don't you love it, when things come together in a way Easter Eggs more or less engineer themselves?
Are you talking about my logo on the silk screen of the PCB?
@@bytesizedengineeringlook at how you named your resistors and diodes... On your Star Wars themed project 🤖
@@ncot_tech shut the front door! I didn't even notice that until now! Ahahaha 😂😂😂😂
@@ncot_tech I usually try to pair up reference designators, so in this case resistor 2 is paired with diode 2! Can't believe I missed that
@@bytesizedengineering No, about the R2-D2 labeling. Cooincidence, I know, but it's on a PCB for a Star Wars Lightsaber, so I count it as easter egg.
Just the right amount of impractical...
A glow in the dark cover for that Sharpie and you got it going on!
9:40 Wouldn't be less trouble if the connectors being attached using a spring? no welding required...
That was my original plan when I thought I could get this made out of aluminum. It would have simplified things quite a bit
Hi, what you said about the battery isn’t quite true. The entire external case is a negative on most 18650”s.

Awsome
how do you charge it?
