When batteries are connected in parallel, the overall capacity and current output of the battery bank increase, while the voltage remains constant. Each additional battery contributes to the total energy storage, effectively extending backup time within the same voltage system.
Operating batteries in parallel improves the battery power system management and resolves the problems of conventional battery banks that arrange batteries in series. This method allows the independent control of discharging currents from each battery, while coordinating them to provide a full amount of the load current.
Here we connected 4 batteries in parallel. Each battery has a capacity of 125Ah and a voltage of 12v. According to the description, the total battery capacity is calculated by multiplying the number of batteries by the capacity of each battery: Total Battery Capacity = 4 × 125Ah
Size wire to connect batteries in parallel Choosing the right battery cable size is critical for both safety and efficiency. In a parallel battery bank, the wires between batteries or from batteries to the busbar carry only the current from individual units. These wires should be sized to handle the maximum current of a single battery.
