Anyway, 1 is internal, 2 is external. Take off external battery and power up. You will know for sure which of the batteries inside. So based on what I'm seeing here, it looks like one of my batteries is at 50% battery health and the other is close to 100%. Any idea which one is the internal and which is the external?
The battery’s chemical compounds undergo a reverse reaction, releasing energy in the form of electrons, which flow through the circuit and power the device. The power output of a battery depends on its design and capacity. The voltage and current produced by the battery determine the amount of power it can supply to the connected device.
When the battery is connected to a circuit, an electric current flows from the battery to the connected device. The battery’s chemical compounds undergo a reverse reaction, releasing energy in the form of electrons, which flow through the circuit and power the device. The power output of a battery depends on its design and capacity.
A battery's internal resistance is the resistance to the passage of electric current inside the battery. The ionic resistance in the electrolyte, the inherent resistance of the materials, and contact resistance at component interfaces are a few of the causes. Several factors, including the internal resistance, can impact the battery's performance:
Although the battery management system has relatively complete circuit functions, there is still a lack of systematic measurement and research in the estimation of the battery status, the effective utilization of battery performance, the charging method of group batteries, and the thermal management of batteries.
The input/output characteristics of batteries determine their performance, capacity, and charging/discharging capabilities. When it comes to battery input, it refers to the power or energy supplied to the battery for charging.
