Model NO.: RFNT3

    Big LCD display  

                                     Warranty: ONE year

Function:*Charge:Active, pre-charge, constant current and constant voltage are the stages of charging mode. The initial charging mode depends on the battery voltage, so active and pre-charge don't happen to every batteries.*Discharge:Constant current discharge for double loads.*Test:Testing time is 30 seconds and the purpose is to check both the charging and discharging performances.*Capacity Correction: The battery capacity value in the battery management chip will different from the actual capacity after a battery goes through many recycling cycles. It will affect the use of the battery when the difference reaches a certain degree. Capacity correction is to deep discharge a battery and then fully charge, which will correct the capacity value in the battery management chip.*50% Capacity: CD50%: charge firstly, and then discharge to 50% capacityDC50%: discharge firstly, and then charge to 50% capacity*Online Functions:Tester can be connected with master machine via a USB port. Users can monitor, control and set parameters via Battery Manager software in the master machine.*Monitoring:Battery information can be monitored via three windows.*Control:Battery Manager can control slave machine completely. Right-click menu on the battery bar includes the related commands.*Parameters:Users can set working parameters via set parameter window in Battery Manager.Features:

*With one channel, supporting one intelligent battery*Supporting charge, discharge, test, capacity correction, charge / discharge 50% capacity*LCD for displaying battery informaiton*LED for indicating working status*With charge-key, discharge-key, backlight-key and function-key*Pre-charge, fast charge and constant voltage charge for charging stages and the variation range of the values of the

constant current and the constant voltage is less than 1%*Constant current for discharging*With a USB port for connecting with computers, master machine can monitoring and control slave machineBasic Parameters:
