      1,Q: What's the main product in GEB?                                                                       

         A: Rechargeable battery. Li-ion, Lipo battery and power battery pack.

      2,Q: What is overcharge?                                                                                             

         A: After charge, tested the batteries' initial state and capacity. Charge to 10.0V at 3C current, then charge to 0.01C at CV mode. Observe changes in battery appearance.

      3,Q: What is over discharge?                                                                                       

         A: After charge, test the batteries' initial state. When the batteries are normal, discharge to 0V at 0.5C. Observe changes in battery appearance

      4. Q: Can I have a sample order?
