Table 3-4, Battery Type To Charge Voltages - Magnum Energy ME-RC Owner's Manual

3.0 Setup
Info: The voltage settings shown in Table 3-4 are based on the Bat-
tery Temperature Sensor (BTS) at a temperature of 77° F (25° C),
or not connected. If the BTS is connected, the actual charge voltage
will increase if the temperature around the BTS is below 77° F (25°
C), and decrease if higher than 77° F (25° C). This ensures the bat-
teries receive the correct charge voltage regardless of temperature.

Battery Type (CC/CV) –
Current/Constant Voltage (CC/CV) charging method with an adjustable
charge voltage and a setting that limits output current—if needed. It
consolidates all the battery charge settings that are required for a 2-stage
charging cycle (i.e., Constant Current and Constant Voltage).
Note: The CC/CV settings only display if CC/CV has been selected from
the 04 Battery Type
Info: If 04 Battery Type is set to CC/CV, the following menus are
no longer accessible and display "CC/CV Controlled" when selected:
03 Absorb Time, 05 Charge Rate, and 09 Final Charge. This is to
prevent charging confl icts that could occur while in the CC/CV profi le.
Max Amps – Sets the maximum charge amperage allowed to charge
the batteries during the CC/CV charge cycles. The range of settings
are provided to limit the charge current to the battery bank, which
helps prevent battery overheating caused by charging at too high a
charge rate.
Default: 200 ADC
Range: 20 - 990 ADC
Chg Volts – Sets the voltage level at which the charger will hold
the batteries during the Constant Voltage cycle.
Default: 13.8 VDC (12v), 27.6 VDC (24v), 55.2 VDC (48v)
Range: OFF, 12.0-16.0 VDC (12v), 24.0-32.0 VDC (24v), 48.0-64.0
