   To manage disputes effectively, establish clear communication channels and a written agreement outlining all terms and conditions before the transaction. In the event of a dispute, initiate discussions with the supplier to resolve the issue amicably. If necessary, refer to the terms of your agreement regarding returns, warranties, and liabilities. If resolution efforts fail, consider mediation or arbitration as a more formal method to settle disputes without resorting to litigation, which can be costly and time-consuming.

8. What safety measures should I consider when using 3.7V 18650 batteries?
   Safety is paramount when dealing with lithium-ion batteries. Ensure that the batteries you source have built-in protection circuits to prevent overcharging, over-discharging, and short-circuiting. Familiarize yourself with proper handling and storage protocols, such as avoiding extreme temperatures and humidity. Additionally, provide training for your team on safe usage practices and emergency procedures in case of battery malfunctions. Regularly inspect batteries for signs of damage or wear, and dispose of them according to local regulations to minimize environmental impact.
