battery monitoring system?

A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack), such as by protecting the battery from operating outside its safe operating area, monitoring its state, calculating secondary data, reporting that data, controlling its environment, authenticating it .

A battery management system (BMS) is an electronic regulator that monitors and controls the charging and discharging of rechargeable batteries. Battery management systems of various types are used in most devices that use rechargeable batteries. ... Multi-cell systems may monitor and control conditions of individual cells

The Orion Battery Management System (BMS) performs three primary functions: ... It does this by constantly monitoring every cell in the battery pack and calculating exactly how much current can safely go in (source, charge) and come out (load, discharge) of the battery pack without damaging it.

For the simplest solution, use a stopwatch or a stopwatch app (the default clock app on Android and iOS includes a stopwatch), making sure to start as you begin using your laptop with a full battery. Stop the watch whenever you turn off the machine or put it to “sleep,” and see how long it lasts.

Then disconnect the negative clamps from both batteries, followed by the positive clamps, do not allow the positive and negative clamps to touch and cause a short circuit. Once the battery has reached approximately 10.8 volts, the BMS will reset and allow current to flow and be detected by your charger.
