Wiring & Installation Steps
Step 1: Initial Connection
Connect the B- to the battery negative terminal. Ensure the B- is welded to the stub first, then connect the cables (ensure cables are removed from BMS before wiring).
Step 2: Wiring Sequence
Start from B- (total negative terminal). Connect B1 to the positive of cell #1, B2 to cell #2 positive, B3 to cell #3 positive, and continue in sequence.
Step 3: Voltage Testing
Test voltage between adjacent lines. Li-ion should be < 4V, LFP should be < 3.5V. Insert the line after checking.
Step 4: Final Connection
Connect the negative terminal of the charger and load to P-/C-. Use bold cables for B- and P-/C- wiring.

Frequently Asked Questions
How do I judge what material my battery is?
Check the battery body. If the nominal voltage is 3.2V, it is LiFePo4. If it shows 3.6V or 3.7V, it is a Li-ion or Li-polymer battery.
How is the product quality guaranteed?
We maintain high standards through pre-production samples before mass production and a final 100% inspection before every shipment.
What types of products are available for purchase?
We offer Battery Pack BMS, LiFePO4/Lithium Ion PCM, Protection Circuit Boards, and complete Battery Packs.
What are the advantages of these protection boards?
Our products are manufactured using advanced SMT equipment and a scientific quality management system to ensure high reliability and environmental safety.
What payment and delivery terms are accepted?
We accept FOB and EXW delivery terms. Payments can be made via T/T, PayPal, or Western Union in USD or CNY.
How do I get a recommendation for my specific project?
Simply provide your battery's relative voltage, cell count, and required current (A) or equipment details, and we will recommend the most suitable BMS for you.
