Battery Optional Instructions:
Please select the corresponding option according to the type of your battery and the number of cells in series. Ordinary lithium batteries and ternary lithium batteries are generally nominally 3.7V/cell and fully charged at 4.2V. Lithium-iron batteries are generally rated at 3.2V/cell and fully charged at 3.7V. Lead-acid batteries are generally nominally 12V/block and fully charged at 13.8V-14.5V.
Ternary lithium battery:
When the battery voltage is greater than N×3.21V+-1%, 1 grid of power is on (Note: N is the number of battery cells, N=2-7)
When the battery voltage is greater than N×3.31V+-1%, it will light up 2 grids of power
When the battery voltage is greater than N×3.48V, +-1% lights up 3 grids of power
When the battery voltage is greater than N×3.61V+-1%, it will light up 4 grids of power
When the battery voltage is greater than N×3.73V+-1%, it will light up 5 grids of power
When the battery voltage is greater than N×3.86V+-1%, it will light up 6 grids of power
When the battery voltage is greater than N×3.97V+-1%, it will light up 7 grids of power
Lithium iron phosphate battery:
When the battery voltage is greater than N×2.72V+-1%, 1 grid of power is on (Note: N is the number of battery cells, N=2-8)
When the battery voltage is greater than N×2.81V+-1%, it will light up 2 grids of power
When the battery voltage is greater than N×2.90V, +-1% lights up 3 grids of power
When the battery voltage is greater than N×2.98V+-1%, it will light up 4 grids of power
When the battery voltage is greater than N×3.07V+-1%, it will light up 5 grids of power
When the battery voltage is greater than N×3.16V+-1%, it will light up 6 grids of power
When the battery voltage is greater than N×3.24V+-1%, it will light up 7 grids of power
12V lead acid battery:
When the battery voltage is greater than N×10.8V+-1%, 1 grid of power is on (Note: N represents the number of battery cells, N=1-2)
When the battery voltage is greater than N×11.2V+-1%, it will light up 2 grids of power
When the battery voltage is greater than N×11.5V, +-1% lights up 3 grids of power
When the battery voltage is greater than N×11.8V+-1%, 4 grids of power are on
When the battery voltage is greater than N×12.2V+-1%, it will light up 5 grids of power
When the battery voltage is greater than N×12.5V+-1%, it will light up 6 grids of power
When the battery voltage is greater than N×12.8V+-1%, it will light up 7 grids of power
Button function 1. Control the backlight
     Short press - switch the backlight on and off
2. Set the battery type and number of strings (only the battery type and number of strings can be correctly displayed)
     1. Press and hold the button for more than 3 seconds to switch to the battery type selection interface Barrery.
     In the battery type interface, short press to select the battery type, the battery type can be switched between Pb12V / Li3.7V / Fe3.2V
     Pb12V--12V lead-acid battery
     Li 3.7V - ternary lithium battery
     Fe3.2V--Lithium Iron Phosphate Battery
     2. After selecting the battery type, press and hold the button for more than 3 seconds to switch to the Number interface for selecting the number of battery strings.
     In the battery string number interface, short press to select the battery string number NS (N represents the number of strings)
     12V lead-acid battery - N=1/2
     Ternary lithium battery - N=2/3/4/5/6/7
     LiFePO4 battery - N=2/3/4/5/6/7/8
     3. After selecting the number of battery strings, press and hold the button for more than 3 seconds to return to the normal interface
