Car battery battery voltage and power display 12v24v support lithium battery USB support multi-protocol fast charge
Battery / lithium voltage and energy meter
Dual fast charge USB output
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.产品
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 / APPLE
Product parameters

Battery 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 3.2V / cell and fully charged with 3.7V. Lead-acid batteries are generally rated at 12V / block and are charged at 13.8V-14.5V.
