1. Supports 8.4V High-Voltage Servo, You Can Directly Test The Servo Function With 2S Lithium Battery! 2. With Backlight And Balanced Discharge Function (Built-In 2w Discharge Power). 3. The Discharge Module Can Also Be Expanded To Achieve Balanced Discharge. 4. After Expanding The 150W Discharge Module, The Discharge Current = 150W/12.6 (Battery Voltage/3S Lithium Battery As An Example) = 11.9A 5. The 150W Discharge Module Requires Cellmeter 8 To Perform The Discharge Function. If Purchased Separately, No Functions Can Be Achieved. 1. Product Name: Cellmeter 8 Multi-Function Tester 2.
