Current sensing - The measured battery current is used by the charger so it knows the exact tail current at which the absorption stage should end and the float (or equalisation) stage should start. To measure the charge current all charge currents from all chargers are combined, or if a battery monitor is part of the network the actual battery current will be used.

For example, charging a 100 Ah battery at 0.1 C would mean a charging current of 100 x 0.1 = 10A. Likewise for discharge current. How do can I increase the current discharge for this particular battery? The discharge current of a particular battery would be dependant on its voltage and the load resistance.
The PWM load covers two stages: transient time (ttran) and sampling time (tsample). ttran measures how fast the boost converter regulates back to the targeted output voltage after an abrupt change in load current or supply voltage. tsample is a constant value once the

The devices work by not being constant current and constant voltage at the same time. You set a voltage (V) for the output. You set a current (A)for the output. It will supply constant V for any current up to A. When the current your circuit draws goes above A, then it will reduce the voltage to keep A at the value set. Example: V set to 10V; A
Direct Current (DC) flows in a constant direction and therefore isn''t changing. Alternating Current (AC) continuously changes polarity (alternates direction), so the magnetic
Current sensing - The measured battery current is used by the charger so it knows the exact tail current at which the absorption stage should end and the float (or equalisation) stage should

$begingroup$ However you end up measuring the capacity, also consider things like environmental conditions such as temperature. In general, temperature tends to accelerate chemical reactions (such as that in a battery), so if you know the highest temperature you would expect this system to exist in, you could find (Theoretically) a maximum battery life
Measure the current: Use a data acquisition system or a microcontroller with an analog-to-digital converter (ADC) to measure the current flowing in and out of the battery. Integrate the current over time: Integrate the

current into the battery until the battery voltage reaches a voltage setpoint. The charger then operates in a constant voltage mode, supplying the current required to maintain the voltage. Most lead acid batteries have a voltage setpoint of 13.8V at 25oC. The current limit is set depending on the exact battery and charge time requirement.
To adjust the voltage we have to do a couple of steps. Connect the converter with the battery or other power source. Set the multimeter to read the voltage and connect the output of the converter to it. Now you can already see the voltage on the output.

You don't "adjust" output current. Loads draw whatever amount of current they need, provided the power supply can deliver it. If your total load exceeds the buck converter's rating of 3A, then you will be overloading it. If your total load is less than 3A, then you need not adjust anything.
