From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Found this cute little guy. Battery bms seems to either be dead or cell voltage too low. Has anyone in the Linux community revived a BMS before or recharged from zero?

Nice trick but there's a reason the charger is designed to not do what you're getting it to do. Preventing explosions and such. I'd recommend looking up why/how the chemistries are different at low voltage so you can ride the line more safely

Absolutely. I've only done it once or twice, just long enough to get the one low cell voltage high enough to switch back to lipo mode. Also, all the lipo charging I do is inside of a steel ammo can. My drone buddy teases me about it but I don't care, big and/or lipo batteries are fucking scary.

The ammo can is a solid idea, wish I thought of that myself. That would raise the safety factor enough for me to give it a try once or twice as well. Still, covered outdoors area or similar. Agreed on having a healthy fear/respect for big cells, it's wild how much power we can fit in a battery these days and even more so to watch it escape.

If you try the ammo can idea make sure you poke a hole in it otherwise you run the risk of it becoming a bit of a pressure vessel.
