Features: Longer service life Touch switch button, perfect hand feeling Dual IC integrated circuit control, more stable Products are suitable for lead-acid 12V, 24V, 36V, 48V (8-70V) Products for 3.7V lithium series multi-platform, 2 series, 3 series, 4 series, 5 series, 6 series, 7 series, 8 series 9 series 10 series 11 series 12 series 13 series 14 series 15 series 16 series 17 series 20 series 21 series 23 series 24 series S1: %/V 2S rotating display Percentage of power and voltage are automatically cycled and displayed alternately; S2: inactive 10S sleep Battery capacity display automatically hibernates after 10 seconds to save power, press function key for 10 seconds to wake up the power display; S3: switch on the backlight The battery capacity display turns on or off the power backlight; S4: display logo (for small battery icon) Logo icon is located below the battery symbol on the left side of LCD, logo is displayed when it is turned on; S5: Discharge mode selection Power display two kinds of battery discharge curve, different environment conversion to choose the appropriate battery discharge mode; Setting steps: 1. Disconnect the module power supply, long press the setup key until the module is powered on. The display shows the current power setting parameters; 2. Press the setup key to select P/L/F, (P=12V lead-acid, L=3.7V lithium battery, F=3.2V lithium iron phosphate battery); 3. Press the function key to set the number of battery strings, select the number of strings according to the up and down keys of the function key and setting key; 4. Long press the function key to enter the advanced setting interface, use the setting key to select S1-S5, and the enter key to select or cancel the current mode; 5. Re-energise the power after the setting is completed, the power supply automatically saves the setting data. For example, 10 lithium batteries power supply, turn on the percentage of power and voltage automatically rotating display (S1 mode) Operation: disconnect the power supply of display module, long press the setup key to energise the power module, short press the setup key to select L, press the function key to select 10, long press the function key to select S1, and re-energise the power supply.
