Never solder while energized. When soldering the main board's + and - wires, ensure these wires are de-energized to prevent 99.99% of accidents.\u003c\/p\u003e\u003cp\u003e2. The main board only has + and - terminals. Soldering while energized risks burns from hand tremors. Always disconnect power before soldering, connecting the main board's + and - first. The battery pack's negative terminal must be soldered last! The motherboard's two wires cannot balance the battery; the balancing protection function resides on the lithium battery protection board.\u003c\/p\u003e\u003cp\u003e3. The battery level may not display correctly upon first power-up but will normalize after a few cycles.\u003c\/p\u003e\u003cp\u003e4. The default capacity is 500mAh per cell. Significant variations may cause inaccurate battery level display, but this does not affect other functions. Overcharging or over-discharging is not a concern.\u003c\/p\u003e\u003cp\u003ePackage Contents\u003c\/p\u003e\u003cp\u003eModule*1\u003c\/p\u003e\u003cp\u003eType B\/Type C\u003c\/p\u003e\u003cp\u003eProduct Features\u003c\/p\u003e\u003cp\u003e1.

Protection board wiring: For a 4S battery pack, starting from the negative terminal, the first positive terminal is B1 (4.2V, 3.6V for LiFePO4). Subsequent terminals are B2 (8.4V), B3 (12.6V), and B+ (positive terminal at 16.8V). Connect the protection board's P+ and P- to the main board's positive terminal.\u003c\/p\u003e\u003cp\u003e2. If the battery has charge but fails to power on after connection, first activate it by charging via the C port. All batteries require activation regardless of initial charge level.\u003c\/p\u003e\u003cp\u003e3. After charging activation, the display may show 0 or 100%. Initial power-up may not accurately reflect charge level; normal display resumes after one charge\/discharge cycle.\u003c\/p\u003e\u003cp\u003e4. During use, if charging stops at 80% or discharging cuts off at 20%, this indicates voltage inconsistency. In severe cases, a fully charged battery may show 4.2V while others drop below 3V, rendering the entire pack unusable.\u003c\/p\u003e\u003cp\u003eImportant Notes:\u003c\/p\u003e\u003cp\u003e1. Solder with power disconnected. Connect main board + and - first; solder battery pack negative terminal last.\u003c\/p\u003e\u003cp\u003e2. The main board's dual wires cannot balance batteries. Balancing protection functions reside on the protection board; add a lithium battery protection board if needed.\u003c\/p\u003e\u003cp\u003ePackage Contents:\u003c\/p\u003e\u003cp\u003eModule*1\u003c\/p\u003e\u003ch3\u003eOptions\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Type B, Type A, Type C\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003ch4\u003eQ: What is the 4S PD 100W Fast Charging Module 20V 5A Power Charge?\u003c\/h4\u003e\u003cp\u003eA: The 4S PD 100W Fast Charging Module 20V 5A Power Charge is a quality electronics accessories pick.
