4S 10A BMS Battery Protection Board with Bluetooth and Temp Sensor

Q1: What certifications do your BMS/protection boards hold for global compliance? A: Our products comply with CE, RoHS, and UL standards. Custom certifications are available for OEM/ODM projects. Full documentation ensures seamless market entry. Q2: Can you customize BMS parameters for LiFePO4, NMC, or other battery types? A: Yes. Provide voltage range (e.g., 12V-72V), cell configuration, discharge current (up to 300A), and communication needs (CAN/RS485/Bluetooth...) for tailored solutions. Q3: How does your BMS prevent critical failures like overcharge or short circuits? A: Multi-layer protection includes: - ±25mV voltage balancing accuracy - Ultra-low impedance MOSFETs for precise current control - Real-time temperature monitoring via NTC sensors - SOC/SOH tracking with industrial-grade ICs Q4: What is your minimum order quantity and lead time? A: Standard MOQ: 1 units (3-7 days). Bulk orders (10,000+ units) qualify for 10-day expedited production and volume discounts. Q5: Do you offer waterproof BMS for EVs or marine applications? A: Yes.feature wide-temperature operation (-40°C to +85°C), vibration resistance, and automotive-grade connectors. Custom sealing options available. Q6: How to verify compatibility with my existing battery design? A:Share your requirements such as battery layout (e.g., 4S20P), data and features. Our engineering will specifically evaluate your project and provide free design optimization support. Q7: What communication protocols do smart BMS support? A: Standard: CAN BUS, RS485/RS232, Bluetooth with mobile apps. Custom protocols (IoT/cloud integration) and accessories (LCD displays, PC tools) are available. Q8: Can I request samples and technical documentation? A: Get samples through “Contact Customer Service” for inquiries and receive partial sample cost credit for bulk purchases. Contact customer service to get the verified general specifications; OEM documents need to be verified credentials. Q9: What warranty and technical support do you provide? A: 1-3 years quality guarantee period (please contact customer service for details). For verified cases, critical replacement parts will be shipped within 48 hours. Q10: How to diagnose potential BMS failures? A: Check cell voltage consistency (max 1.0V difference). Symptoms like no charge/discharge indicate BMS issues; uneven cell performance suggests battery problems.
