Zk-bc 4.5-32v 12v 24v Lead-acid Lithium Battery Voltmeter Ammeter

Voltage / power / power percentage One screen displaySupport 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 moduleDual 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, 9V@2.5A, 12V @ 2A, etc.)USB efficiency: 90% -97%Supports multiple fast charge protocolsInput anti-reverse protectionOutput overcurrent, short circuit protectionWorking temperature: -10 Celsius - 60 CelsiusOperating humidity: 10-80% (non-condensing)Colour:blackMaterial:plasticPackage Contents:1 * Vehicle Battery Testernote: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.Only the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
