Direct current (DC) is the type of current most commonly produced by batteries. With DC, the flow of electric charge is unidirectional, moving from the battery''s positive terminal to its negative terminal.

By Irena Zhuravchak and Volodymyr Ilchuk | Tuesday, June 27, 2023 Charging a battery using the constant-current/constant-voltage (CC/CV) method involves using the constant current in the initial state of charging and then switching to constant voltage in the later stages of charging, when the battery reaches the set charge level.
You do not need to add any additional resistance. Also, 6 Ah is the C rating of the battery. The C and discharge rate is limited by the battery internal resistance, which leads to heating during charge and discharge. If you add cooling to the battery it can sustain a higher discharge rate, but you should consult the manufacturer.
When a battery is connected to a circuit, the electrons from the anode travel through the circuit toward the cathode in a direct circuit. The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current.
The C-rate is just the current you are charging, or discharging into the battery that has been normalized to current that the battery can supply for one hour before dying* The Amp-hour rating of a battery is the rating that tell you what level of current a battery can theoretically supply before dying.
No. If the load is rated to operate on 24 volts, and requires 12 amp, you just connect it directly to the 24 volt battery. You do not need to add any additional resistance. Also, 6 Ah is the C rating of the battery. The C and discharge rate is limited by the battery internal resistance, which leads to heating during charge and discharge.
As the State of Charge (SOC) increases, the battery charging current limit decreases in steps. Additionally, we observe that the battery voltage increases linearly with SOC. Here, Open Circuit Voltage (OCV) = V Terminal when no load is connected to the battery. Battery Maximum Voltage Limit = OCV at the 100% SOC (full charge) = 400 V.
