Features: 6-60V battery, lithium battery can be used; LCD display, battery voltage, charging percentage and charging for time at a glance; It can automatically charge and control, can control the charging for time, and can set and upload the corresponding parameters through the serial port. Charging for time recording function: When the charging for time control is not turned on, the product will record the complete for time once. When entering the for time display interface, the charging for time will be flashed and displayed; then exit the for time display interface or clear it when the next charging is turned on (relay is turned on). Parameter automatic detection: After setting the parameters and exiting, if the lower voltage limit dn ≥ the upper limit voltage up, the system will flash and display "ERR" as a reminder. Battery connection detection: This product is attached to the battery, if the battery is not connected, the system will display "nbE" in the lower line as a reminder. This model is suitable for use within the voltage range of minimum 6V and maximum 60V. The maximum expenditure level is 48V, because the 48V battery is fully charged at about 60V, and it will burn if it is higher.
