1. Ensure your power bank can output at least 1A(1000mAh) at 7.2V.
2. Connect the battery's positive terminal to the power bank's positive terminal and its negative terminal to the power bank's negative terminal.
3. If the battery has a built-in low voltage cutoff, it may automatically disconnect the battery once fully charged.
4. If your battery doesn't have an automatic cutoff, keep an eye on the voltage and disconnect manually around 8.4V.
Using a Variable Power Supply
1. Set the power supply to 7.2V and 1A.
2. Connect the battery's positive terminal to the power supply's positive terminal and its negative terminal to the power supply's negative terminal.
3. Once the battery reaches the right voltage, disconnect the power supply.
Precautions:
- Monitor the voltage continuously during the charging process to avoid overcharging.
- Be cautious when handling Lithium-ion batteries as they can be prone to damage or accidents if mishandled.
