It continuously monitors the voltage of each individual cell through balance wires. During charging, it prevents any cell from exceeding 4.25V and balances cells to equalize voltages. During discharge, it cuts off output if any cell drops below 2.5V, protecting cells from deep discharge damage. The onboard MOSFETs also limit current to 10A and instantly disconnect the circuit during a short circuit event. Once the fault is removed, the board auto-recovers without requiring manual intervention.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Guide\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eB-:\u003c\/strong\u003e Connect to the negative terminal of the first cell (Cell 1 negative)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBM1:\u003c\/strong\u003e Connect to the junction between Cell 1 positive and Cell 2 negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBM2:\u003c\/strong\u003e Connect to the junction between Cell 2 positive and Cell 3 negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eB+:\u003c\/strong\u003e Connect to the positive terminal of the third cell (Cell 3 positive)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eP-:\u003c\/strong\u003e Output negative - connect to your load or charger negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eP+:\u003c\/strong\u003e Output positive - connect to your load or charger positive (often shared with B+)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eNote: Always double-check polarity before connecting.
