Battery Power Source section ƒ Enabled: If checked, a battery is the selected power source. ƒ Battery Type list: Select battery type being used to power PowerLab 8. Values in this list’s templates are a starting point. Change the following settings as needed. ƒ Show Warning at 50% DOD: If checked, PowerLab 8 measures battery voltage when first connected. If the battery is below 50% depth of discharge (below that point, most flooded Lead Acid batteries are damaged), PowerLab 8 beeps and issues a warning. Press the BACK button to cancel the operation on the PowerLab 8, then correct the situation. (You could press the ENTER button to proceed, but this is not recommended.) ƒ Battery Low Voltage Out: Set to low voltage cutoff value. If battery reaches this voltage, charging stops to prevent over-discharge. 11.00V is recommended for most 12V batteries. For a 24V supply battery PowerLab 8 auto-detects two 12V batteries in series and doubles the Battery Low Voltage Out setting selected. 43 ƒ Battery Max Amps Out: Set for maximum supply battery current draw. If the charge rate is set higher than the input current allows, the PowerLab 8 will draw no more than the level set here, which may limit output current to the pack. If Battery Max Amps Out is set too high, the battery’s output voltage may drop below the Battery Low Voltage Out setting and charging will stop and the input battery could be damaged from excessive current draw. ƒ Enable Regenerative Discharge: If checked, pack discharge energy (up to 40A/1344W) is sent to supply battery during discharge cycles. If not checked, discharge is dissipated internally (limited to 100W). ƒ Regen. Amps IN to Pb: Set to maximum regenerative current to supply battery. Consider battery chemistry and size when setting this value. For example, Lead Acid batteries should not be charged at a rate higher than C/8. CAUTION: An excessively high and sustained regenerative current back into the supply battery can harm the battery and reduce its useful life. Always follow the input battery manufacturer’s recommendations when setting up for regenerative discharge. ƒ Regen. Charge Voltage IN to Pb: Set to maximum regenerative voltage applied to supply battery. For a 24V supply battery, PowerLab 8 will automatically double the value set here. If the regenerative voltage reaches the value set here, PowerLab 8 switches to internal discharge to prevent the supply battery from being overcharged.
