Here’s how you can connect 8 batteries in series and parallel to achieve a specific voltage and capacity:

How to connect 8 batteries in series and parallel:

Option 1: 4S2P Configuration

  1. Series Connection (4 batteries in series):
    • Connect the positive terminal of the first battery to the negative terminal of the second battery.
    • Continue this process until you have all 4 batteries connected in series.
    • The positive terminal of the first battery and the negative terminal of the fourth battery are your main terminals for the series connection. This configuration will give you the combined voltage of 4 individual batteries.
  2. Parallel Connection (2 sets of series-connected batteries in parallel):
    • Now, take two sets of the series-connected batteries from step 1.
    • Connect the positive terminal of the first set to the positive terminal of the second set.
    • Connect the negative terminal of the first set to the negative terminal of the second set.
    • The positive terminal of the first set and the negative terminal of the second set are your main terminals for the parallel connection. This configuration will double the capacity while maintaining the combined voltage of the series connection.

Option 2: 8S1P Configuration

  1. Series Connection (8 batteries in series):
    • Connect the positive terminal of the first battery to the negative terminal of the second battery.
    • Continue this process until you have all 8 batteries connected in series.
    • The positive terminal of the first battery and the negative terminal of the eighth battery are your main terminals for the series connection. This configuration will give you the combined voltage of all 8 batteries.
  2. Parallel Connection (1 set of series-connected batteries in parallel):
    • Take the entire set of 8 batteries connected in series.
    • Connect the positive terminal of this set to the positive terminal of one battery.
    • Connect the negative terminal of this set to the negative terminal of one battery.
    • The positive terminal of the series-connected set and the negative terminal of the single battery are your main terminals for the parallel connection. This configuration maintains the combined voltage of the series connection while increasing the overall capacity.

Important Notes:

  • Ensure that all batteries you are connecting are of the same voltage and capacity to avoid imbalances and potential issues.
  • Safety is crucial when working with batteries. Make sure to handle them properly, avoid short circuits, and follow the manufacturer’s guidelines and safety precautions.
