4, Precautions

  1. Positive and negative connections should not be reversed.

  2. Always use the tester within the allowed range.

  3. This model does not support NiMH, NiCd charge test and power supply adapter test. You can buy our EBC-A05 or EBC-A10H.  

  4. The Maximum discharge power is 85W, 4.2V can be 20A, 8.4V can be 10A, higher voltage less than 10A. 


  6. For batteries with a voltage higher than 10V, the maximum charging current should be lower than power current-0.5A.

  7. EB Tester Software and User Manual in English version will send by email if you need.
