Your Cells Require Top-Balancing

1. Connect the Cells in Parallel – Link all cells positive to positive, negative to negative to equalise their voltage.
2. Charge Slowly to 3.65V – Use a constant voltage power supply with a low current (≤10A). 
3. Hold at 3.65V Until Current Drops Below 1A – Keep charging until the current naturally drops. This means all cells are fully charged and balanced.
4. Disconnect and Assemble Your Pack – Once balanced, disconnect the cells and build your battery. Avoid long-term storage at full charge.
