OEM & Private Label LiFePO4 Battery Manufacturing: Complete China Factory Guide (2026)
Selling batteries under your own brand costs $3,000-$10,000 to start and takes 45-80 days from first contact to shipment. This guide covers real costs, MOQ by product type, the difference between OEM and private label, and the 5-step process.
OEM vs Private Label: What You Actually Need
People confuse these. The difference matters because it changes your MOQ, cost, and timeline:
| Service Type | What You Get | MOQ | Setup Cost | Timeline |
|---|---|---|---|---|
| Private Label | Your logo on existing factory design + custom packaging | 20-50 units | $200-$800 | 30-45 days |
| OEM (Standard) | Custom casing color + logo + your spec sheet | 50-100 units | $3,000-$8,000 | 45-60 days |
| OEM (Full Custom) | New form factor + custom BMS + proprietary design | 200-500 units | $10,000-$40,000 | 60-120 days |
For most importers, private label or standard OEM is the right starting point. Full custom OEM requires engineering teams on both sides and only makes sense at 1,000+ annual units.
Step-by-Step OEM Process
1. Define Your Specification
Send the factory these 7 data points. A serious manufacturer returns a quote in 3-5 business days. If they cannot quote within a week, find another supplier.
- Voltage: 12V, 24V, 48V, or 51.2V nominal
- Capacity: 50Ah / 100Ah / 200Ah / 300Ah — or kWh target
- Form factor: Wall-mounted, rack-mounted (19-inch), stackable, portable, custom
- Target certifications: CE (EU), UL 1973 (US), UN38.3 (transport), IEC 62619
- Cell preference: EVE, CATL, REPT, Gotion — or "factory recommendation"
- Communication: CAN, RS485, RS232, WiFi, Bluetooth
- Annual volume estimate: 100 / 500 / 1,000+ units — determines your price tier
2. Review Quotation and MOQ
A standard OEM quotation from a Dongguan-area factory breaks down like this:
| Line Item | Cost | Notes |
|---|---|---|
| Unit cost (51.2V 100Ah) | $680-$950/unit | Depends on volume, cell brand, BMS grade |
| Custom casing mold | $2,000-$5,000 | One-time. Waived at 500+ annual volume |
| Custom color finish | $500-$1,500 | Per color, one-time setup |
| Logo — silk-screen | $2-$5 per unit | Works on flat surfaces |
| Logo — laser engraving | $8-$15 per unit | Metal casing only, permanent |
| Custom packaging | $200-$500 design + $3-8/box | Your brand colors, manual, unboxing experience |
| Sample production (2-5 units) | $500-$2,000 | Credited against first bulk order at most factories |
| Pre-shipment inspection | $500-$800 | SGS/TÜV third-party |
3. Approve Pre-Production Samples
The factory produces 2-5 units to your specification. They ship these to you (air freight, 3-7 days). Test every unit before approving production:
- Capacity test: Charge to 100%, discharge to 0% at 0.5C. Actual capacity should be within 3% of rated
- BMS test: Over-voltage cutoff, under-voltage cutoff, short-circuit protection
- Communication test: Connect to inverter, verify data reads correctly over CAN/RS485
- Physical inspection: Welding uniformity, casing fit, label alignment, connector quality
If samples pass, sign off in writing. This sample becomes the quality reference for mass production.
4. Branding and Packaging Design
Send the factory these files:
- Logo: Vector format (.AI, .EPS, or .SVG). Minimum 300 DPI if raster
- Color codes: Pantone or CMYK values for casing color
- User manual: PDF in your language(s). Factory handles translation if needed ($200-$500)
- Packaging artwork: Box design with your brand elements, specs table, certification marks
5. Production and Quality Gate
Mass production runs 15-30 days for 50-200 units. Two quality gates exist:
- Inline QC: Factory tests every unit at assembly — voltage, BMS function, charge/discharge cycle
- Pre-shipment inspection (PSI): Third-party inspector randomly samples 10-20% of the batch, verifies all match approved sample. If defect rate exceeds 2%, full re-inspection before shipment
Real Costs: 100-Unit Order Example
Here is the math for ordering 100 units of a 51.2V 100Ah wall-mounted battery under your brand, with custom packaging:
| Cost Item | Amount |
|---|---|
| 100 units × $780/unit | $78,000 |
| Custom packaging design + boxes (100 pcs) | $700 |
| Silk-screen logo (100 pcs × $3) | $300 |
| Pre-production samples (3 units) | $1,500 |
| Sea freight (20ft container, Dongguan→Lagos) | $3,500-$5,000 |
| Pre-shipment inspection | $500 |
| Total landed cost (100 units) | ~$85,000 |
| Per-unit landed cost | ~$850 |
At $850/unit landed cost, a 51.2V 100Ah LiFePO4 battery retails for $1,200-$1,800 in most markets — a 40-110% margin. Distributors selling 200+ units/year recover setup costs in the first batch.
When OEM Makes Sense vs Buying Stock
| Scenario | Recommendation | Why |
|---|---|---|
| First-time buyer, testing market | Stock products | Zero setup cost. Validate demand first. |
| Distributor with existing customer base | Private label | Brand builds repeat purchases. $200-800 to start. |
| Regional distributor, 200+ units/year | Standard OEM | Custom color + brand = differentiated product. Mold cost amortized after 100 units. |
| National distributor, 1,000+ units/year | Full custom OEM | Proprietary design blocks competitors. Engineering cost justified. |
