Do not solder while the device is powered on. When soldering the + and - wires to the main board, ensure the protection board has no output voltage to prevent 99.99% of accidents. 2. The main board has only + and - terminals. Soldering while powered on can easily cause damage if your hand shakes. Please disconnect the power before soldering. Connect the main board’s + and - terminals first. Solder the battery pack’s negative terminal last—solder the battery pack’s negative terminal last!!! The two wires on the main board cannot balance the battery; the balancing protection function is on the lithium battery protection board. Frequently Asked Questions 1. Protection board wiring for a 4S battery pack: Start from the negative terminal. The first positive terminal (b1) is 4.2V. Subsequent terminals are b2 (8.4V), b3 (12.6V), and b+ (positive terminal, 16.8V). Connect the protection board’s P+ and P- terminals to the main board’s + terminal. 2. If the battery has power but the device does not light up or function after connection, please charge and activate it via the C port first. Regardless of whether the battery has power or how much charge it holds, it must be charged and activated. 3. After charging and activation, the display may show 0 or 100. The battery level may not be accurately displayed upon first power-up; it will return to normal after a few charge-discharge cycles. 4. During use, if charging stops at 80% or discharging cuts off at 20%, this is caused by inconsistent voltages. In the worst-case scenario, if the battery voltage drops below 3V while the full charge voltage is 4.2V, the battery becomes unusable. Upgrade Features 1. The main controller has been upgraded to SW6306V, and the USB-A female connector has been upgraded to a 5-pin version. 2. Software update: The screen now displays battery voltage. Customers using this as a startup power supply no longer need to add an external voltmeter. 3. Added a DC 5.5/2.1mm port. This port connects directly to the main board’s + and – terminals; there is no conversion or voltage regulation. The output voltage matches the battery voltage exactly. It can be used to charge the battery at 16.8V or for output, with a current limit of 10A.
