Your Cells Require Top-Balancing
Top balancing makes sure all your battery cells are at the same voltage before you build your pack. This helps them discharge evenly and prevents your battery from shutting down too soon.
How to Top Balance
- Connect the Cells in Parallel – Link all cells positive to positive, negative to negative to equalise their voltage.
- Charge Slowly to 3.65V – Use a constant voltage power supply with a low current (≤10A).
- 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.
- Disconnect and Assemble Your Pack – Once balanced, disconnect the cells and build your battery. Avoid long-term storage at full charge.
