Without going into too many details, a new breakdown of a Tesla cell shows what is inside. A Youtube channel bought 18650 cells from eBay, where the seller claims that they have been extracted ...

In a noteworthy advancement, Group1 has launched the world’s first Potassium-ion battery that has been designed within the widely utilized 18650 cylindrical form factor. “We are excited to ...

I made this amazing battery pack using 18650 cells, performing about 3X better than a LiPo battery of roughly the same weight and size. So instead of flying for 15 min, now you can fly for 45 min.

Draining a battery is easy. Just put a load across the terminals, maybe an incandescent bulb or a beefy power resistor, and wait. What’s quite a bit trickier is doing so safely. Put too large… ...

ARIES RC discharged and disassembled a cell obtained in some way (allegedly) from the Gigafactory. The 2170 cylindrical cells are bigger than the previous 18650 cells, so it stores more energy.

If your battery salvaging operation is too large for a single-cell tester, perhaps it’s time to upgrade to this 40-slot wall mounted unit. Posted in Battery Hacks , Tool Hacks Tagged 18650 ...
