• To ensure you enjoy the longest, most stable runtime, we recommend the following best practices: 1. Synchronized Charging Before Use​ For extended tasks, please fully charge both batteries​ before starting. This helps balance power delivery between the two batteries for optimal performance. 2. Use Matched Batteries​ Whenever possible, pair two batteries of the same capacity and similar cycle life. This maximizes charge consistency and improves overall efficiency. 3. Monitor Performance in Real Time​ If you notice a drop in power, one battery may be nearing depletion. We recommend pausing your work and replacing both batteries with fully charged ones​ to immediately restore peak performance.
