Frequently Asked Questions

Everything About IoT Battery Solutions

What types of IoT batteries does VoltCrave manufacture?
We produce LiFePO4 (18650, 26650, prismatic), Li-ion (18650, 21700), and Li-Po pouch cells in custom packs. Applications span smart meters, security cameras, consumer electronics, automotive T-Box, smart city nodes, power tools, LEV, and medical IoT devices. Every pack includes our smart BMS with multi-protocol communication.
What is the minimum order quantity (MOQ) for OEM battery packs?
Our standard MOQ is 1,000 units for custom battery packs and 10,000 units for custom cell configurations. For prototyping and validation, we offer small-batch runs starting at 50-100 units. We also maintain stock of standard cells for low-volume or pilot program needs. Contact our sales team for project-specific MOQ discussions.
How long does the OEM/ODM development process take?
Typical timeline: requirements review and feasibility assessment in 48 hours, prototype delivery in 2 weeks, full validation and certification pre-compliance in 4-6 weeks, and mass production ramp-up in 4 weeks. Total time from concept to production is approximately 8-12 weeks depending on complexity and certification requirements.
Do you provide samples? What is the sample policy?
Yes, we provide evaluation samples. Custom samples are shipped within 2 weeks of design finalization. Sample fees are credited against your first production order. For standard-cell samples from our existing portfolio, we can typically ship within 3-5 business days. All samples include full test reports and BMS communication protocol documentation.
What BMS communication protocols do you support?
Our smart BMS supports I2C, SMBus v1.1, RS485, and CAN bus as standard. Custom firmware for proprietary protocols is available. All BMS units expose real-time SOC (±3%), SOH, cycle count, cell voltages, and temperature data. Cloud connectivity via JSON/MQTT with remote OTA firmware update and rollback protection is built into every IoT battery pack.
What certifications do your IoT batteries hold?
Our IoT battery products are certified to CE, RoHS, UN38.3, IEC 62133, UL, FCC, and MSDS. We maintain ISO 9001 and ISO 14001 certifications across our manufacturing facilities. For medical IoT applications, IEC 60601 compliance documentation is available. Full certification documentation is provided with every order for your regulatory submissions.
Can you customize form factor, connectors, and labeling?
Absolutely — this is core to our OEM/ODM service. We customize cell selection, pack configuration (series/parallel), enclosure design and material, connector type (JST, Molex, TE, custom pinout), wire harness, heat shrink or plastic casing, label printing with your branding and SKU, and BMS firmware. Your battery ships as your product, with your documentation.
What is the typical lead time for mass production?
Standard lead time is 4-6 weeks for production orders after sample approval. Rush orders can ship in 3 weeks depending on line availability and component inventory. We operate 32 automated production lines with 500K+ monthly capacity across our Dongguan facility — so even large-volume orders stay on schedule.
Where are you located and do you ship internationally?
Our manufacturing facility and headquarters are in Dongguan, Guangdong, China. We ship to 50+ countries worldwide with established logistics for air freight (5-7 days), sea freight (15-30 days), and rail to Europe (12-18 days). We handle all export documentation including UN38.3 test summaries and dangerous goods declarations for lithium battery shipping.
Do you offer NDA and IP protection for custom projects?
Yes, we sign mutual NDAs as standard practice before any detailed technical discussion. Your battery design, connector pinout, BMS firmware binary, enclosure CAD, and all project documentation remain your exclusive intellectual property. We provide full design file ownership upon project completion and do not reuse customer designs for other clients under any circumstances.
How do I start a battery development project with VoltCrave?
Contact our engineering team with your basic specifications: target voltage, capacity range, form factor constraints, connector preference, and volume estimate. We respond within 24 hours with a feasibility assessment, preliminary timeline, and budgetary pricing. No commitment required. For complex projects, we can arrange a technical call with our BMS and cell engineering teams to deep-dive your requirements.
What warranty and support comes with OEM battery products?
Standard warranty is 12 months from shipment date covering manufacturing defects and non-conformance to agreed specifications. Extended warranty options up to 3 years are available for long-lifecycle products. Our LiFePO4 cells are rated for 4,000+ charge-discharge cycles with under 20% capacity degradation. Technical support is available via email, WeChat, and video call throughout your product lifecycle.
