Is it possible to connect four Lithium iron phosphate LiFePO4 batteries in series to make a 12V battery To series four lithium iron phosphate (LiFePO4) cells (e.g., 3.2V 100Ah each) for a 12.8V (4S) pack, connect the negative terminal ( − ) of one cell to the positive terminal ( + ) of the next in a chain, creating a 4S (4-series) configuration. This configuration increases the total voltage to approx12.8V-13.2V while keeping the capacity at 100Ah. Steps for Connecting 4S LiFePO4 Cells 1. Top Balance Cells: Before connecting, charge all four cells in parallel to 3.65V (or 100% SoC) to ensure they have identical voltages. This prevents issues where one cell charges faster than others. 2. Arrange Cells: Place the four cells side-by-side, alternating terminals (+, -, +, -, +, -, +, -). 3. Connect in Series: 1.
