Frequently Asked Questions
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 unit (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.
