Car Battery Battery Voltage and Power Display 12v 24v Support Lithium Battery USB Support Multi-protocol Fast Charge

Car Battery Battery Voltage and Power Display 12v 24v Support Lithium Battery USB Support Multi-protocol Fast Charge Description

Note:1. The power meter defaults to 12V battery mode. Other specifications of the battery need to be set by buttons.2. The USB port fast charge function requires mobile phone cooperation and cannot be activated every time. If it cannot be activated, please plug and unplug a few times. The chip uses Inchip IP6505T, and the circuit is also recommended by the manufacturer. The chip supports mainstream fast charge protocols, but cannot support all the fast charge protocols on the market. Because fast charge is related to many factors such as mobile phone data lines, mobile phone models, mobile phone power, and protocol matching degree, it cannot guarantee that every mobile phone can charge fast Or you can charge fast every time.Product selling points:• Voltage / power / power percentage One screen display• Support multiple batteries, battery type and string number can be set (default 12V lead-acid battery)• Input reverse connection protection, reverse connection does not burn the module• Dual independent USB, using IP6505T fast charge identification chip, support mainstream fast charge protocols such as QC2.0 / QC3.0 / FCP / SCP / MTK / APPLEProduct parameters:Input voltage: DC6V-30V (Note: The USB port is a step-down power supply. If your input voltage is less than 12V, you cannot support 12V fast charge, and the same is true for 9V fast charge)Battery display: 7-segment display-13% 26% 39% 52% 65% 78% 91%Output voltage: 5V by default, automatically adjusted between 3-12V after triggering fast chargeOutput power: up to 24W (5V @ 4A, [email protected], 12V @ 2A, etc.) USB efficiency: 90% -97%Supports multiple fast charge protocolsInput anti-reverse protectionOutput overcurrent, short circuit protectionWorking temperature: -10 ¡æ — 60 ¡æOperating humidity: 10-80% (non-condensing)Installation size: 75mm * 39mmBattery description: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 to 4.2V. The lithium-ion battery is generally nominally 3.2 V / cell and fully charged with 3.7V. Lead-acid batteries are generally rated at 12V / block and are charged at 13.8V-14.5V.Ternary lithium battery:The battery voltage is greater than N × 3.21V + -1%, and the power is on for 1 grid (Note: N is the number of battery cells, N = 2-7)Battery voltage is greater than N × 3.31V + -1%, 2 grids lightBattery voltage is greater than N × 3.48V, + -1% bright 3 cellsBattery voltage is greater than N × 3.61V + -1%, 4 grids lightBattery voltage is greater than N × 3.73V + -1%, bright 5 cellsBattery voltage is greater than N × 3.86V + -1%, with 6 cells onBattery voltage is greater than N × 3.97V + -1%, 7 grids lightLithium iron phosphate battery:The battery voltage is greater than N × 2.72V + -1%, and the power is on for 1 grid (Note: N is the number of battery cells, N = 2-8)The battery voltage is greater than N × 2.81V + -1%, and the power is on for 2 gridsBattery voltage is greater than N × 2.90V, + -1% bright 3 cellsBattery voltage is greater than N × 2.98V + -1%, 4 grids lightThe battery voltage is greater than N × 3.07V + -1%, and the power is 5 grids.The battery voltage is greater than N × 3.16V + -1%, and the power is 6 cells.Battery voltage is greater than N × 3.24V + -1%, 7 grids light12V lead-acid battery:The battery voltage is greater than N × 10.8V + -1%, and the power is on for 1 grid (Note: N is the number of battery cells, N = 1-2)Battery voltage is greater than N × 11.2V + -1%, with 2 cellsBattery voltage is greater than N × 11.5V, + -1% bright 3 cellsThe battery voltage is greater than N × 11.8V + -1%, and the power is 4 grids.The battery voltage is greater than N × 12.2V + -1%, and the power is 5 grids.Battery voltage is greater than N × 12.5V + -1%, bright 6 cellsThe battery voltage is greater than N × 12.8V + -1%, and the power is 7 cells.Key function description:1.Control the backlightShort press-switch the backlight on or off2.
