At a glance we can see the major components you’d expect in a discharger: a fairly simple PCB, four ceramic power resistors, a holder for a single 18650 cell ... when the voltage drops to ...

French researchers have announced a prototype of an 18650 sodium-ion ... choice for rechargeable cells. Lithium has a lot of advantages. It has a high working voltage, and it is lightweight.

I have accumulated a large number of 18650 cells for use in projects like electric ... A simple MOSFET+resistor to handles the discharge. So each cell needed an analogue voltage read and 2 digital IO ...

This curve is used to estimate the state of charge of a battery pack. This method is only valid after a resting period to ensure that the terminal voltage equals the open-circuit voltage. May be used ...
