This BMS is built for high-power applications. It's not just a connector but the key to ensuring your valuable battery pack operates safely, stably, and durably. Whether you're modifying power tool batteries, assembling a spare e-bike pack, or building a portable power station, it provides robust protection for peace of mind.\u003cbr\u003e\u003cbr\u003e🚨 Important Notes Before Buying!\u003cbr\u003e❌ 【Product Clarification \u0026amp; Limits】: This is a protection board, NOT a charger or a finished battery pack! It requires your soldering to a pre-series-connected 3x 18650 battery pack. NOT compatible with 4S or other series configurations. Incorrect connection will damage it!\u003cbr\u003e⚠️ 【Most Common Mistakes \u0026amp; Safety Warnings】\u003cbr\u003e\u003cbr\u003eVoltage MUST Match: For 3S (3-Cell Series) Li-ion batteries ONLY (~12.6V total). Do not use with 1S, 2S, 4S packs or lead-acid batteries!\u003cbr\u003e\u003cbr\u003eWiring Sequence is CRITICAL: Must solder to battery pack in order: B- → B1 → B2 → B+. NEVER skip or reverse connections!\u003cbr\u003e\u003cbr\u003ePower Wire Requirement: For high-current applications (e.g., e-bikes), wires to P- and P+ must be sufficiently thick (recommended ≥12AWG).\u003cbr\u003e✅ 【Required Conditions \u0026amp; Skills】\u003cbr\u003e\u003cbr\u003eRequired Materials: Pre-welded\/soldered 3x 18650 battery pack, high-power wires, soldering iron (and skill).\u003cbr\u003e\u003cbr\u003eRequired Knowledge: Ability to identify battery polarity, understand series connections, basic soldering skill.\u003cbr\u003e\u003cbr\u003eTesting Advice: After assembly, test output voltage and polarity with a multimeter before connecting to load or charger.\u003cbr\u003e🔧 【Difference from TP4056 etc.】: This is a BMS (Battery Management System) for multi-cell packs. The TP4056 is a single-cell Li-ion charging module. They have different functions and applications.
