At Hele Titanium, we specialize in converting raw titanium into superior titanium anodes, embodying our dedication to excellence and quality. Our refined production process guarantees anodes that surpass industry standards in electrocatalytic efficiency and corrosion resistance. Here is a detailed exploration of our anode production methodology:
We begin by sourcing brand-name 18650 or 21700 lithium-ion cells (Samsung, LG, or high-quality Chinese cells). Each cell is tested and sorted by voltage and capacity, ensuring balance and consistency across the entire pack. Accurate matching for internal resistance and capacity Prevents early failure or imbalance during use
Using automatic spot welding machines, cells are connected into series-parallel configurations using nickel strips. This step is critical to forming the correct voltage and capacity of the final pack (e.g., 36V 15Ah, 48V 20Ah). Consistent welds minimize heat damage Reinforced weld points ensure vibration resistance
We install and program the Battery Management System (BMS), which protects against overcharge, over-discharge, short-circuit, overcurrent, and temperature anomalies. Optional Smart BMS with Bluetooth and app support Custom firmware configuration based on client requirements
Battery cells are enclosed within robust plastic, aluminum, or customized molded housings such as Hailong, Dorado, Triangle, or Rear Rack styles. Foam and insulation are added for shock and heat protection. Supports IP-rated waterproofing Branding, labeling, and barcode tagging applied at this stage
Packs are charged and discharged multiple times using programmable equipment to simulate real-world usage. This stabilizes internal chemistry and allows for early fault detection. Verifies pack integrity under load Filters out defective units before shipment
Each pack undergoes full testing for voltage, protection circuit performance, physical durability, and temperature behavior under working load. UN38.3 transport testing MSDS + CE + RoHS verification Optional UL2271-compliant testing on request
Battery packs are carefully packed using anti-static materials, foam-injected cartons, and UN-certified DG shipping boxes. All necessary documentation is included for customs clearance and air/sea transport. Overseas stock available in Poland, USA, and Canada Flexible MOQ and fast sample delivery (3–7 days)

Let’s create a battery pack that powers your unique ideas.
eBike battery pricing can vary significantly depending on the cell brand, configuration, casing type, certifications, and customization level. As a professional lithium battery supplier, JUNDA is committed to helping buyers understand what drives battery cost — so you can make informed, efficient purchasing decisions.
The battery cell is the most critical cost component. Premium brands like Samsung and LG come at a higher price but offer longer cycle life and better consistency. Chinese top-tier cells (such as CATL or Lishen) provide a good balance between cost and performance.
Common Cell Types: 18650 / 21700
Influence on Price: Up to 50–60% of total pack cost
Cell Sorting & Matching: Extra cost for consistency improves safety and longevity
Battery packs are priced by their voltage and amp-hour capacity (e.g. 48V 15Ah vs 48V 20Ah). Larger capacity = more cells = higher price.
Popular Configs: 36V 13Ah / 48V 15Ah / 52V 20Ah
More cells = more power, weight, and heat control needs
Internal layout and complexity can affect spot welding labor time
Some casing molds like Hailong or Dorado are standard and cost-effective, while custom-molded or integrated frame batteries are more expensive due to tooling and assembly complexity.
BMS Options: Basic protection vs Smart BMS with Bluetooth/App
Special features like water-resistance, rail lock, or lighting raise cost
If you require full documentation (UN38.3, MSDS, CE, RoHS, UL2271), the batteries must undergo additional testing and reporting — often increasing cost.
Mandatory for customs clearance and overseas air freight
Full test reports and labels may be bundled or optional
Export shipping adds to the landed cost. Dangerous goods (DG) certification, UN-marked packaging, and air/sea freight fees all contribute.
Stock batteries shipped in bulk = lower cost
Express samples, branded cartons, and regional warehouses = added value
We provide competitive pricing based on:
Transparent bill of materials (BOM)
Real-time lithium cell market pricing
Flexible quotes based on MOQ and customization
Logistics optimization for North America, EU, and Southeast Asia
📩 Share your battery configuration or drawing — we’ll send a quote within 24 hours.
Certified battery packs are essential for international shipping, product compliance, and end-user safety. Whether you’re an OEM brand, importer, or service provider, choosing batteries with the right certifications helps you avoid customs delays, reduce liability, and protect your customers.
Here’s a breakdown of the key certifications every eBike battery should have—especially for markets in the EU, North America, and global transit routes:
✅ UN38.3 (United Nations Transportation Standard): Ensures that lithium batteries can be safely transported by air, sea, or land. Batteries are tested for shock, thermal exposure, overcharge, and impact.
✅ CE Marking: Required for selling batteries in Europe. It confirms the product complies with European safety, health, and environmental protection standards.
✅ RoHS (Restriction of Hazardous Substances): Verifies that the battery components do not contain dangerous materials like lead, cadmium, or mercury—important for sustainable and safe products.
✅ MSDS (Material Safety Data Sheet): Mandatory for customs clearance and warehouse storage. It provides details on chemical composition, handling, and fire response.
✅ UL2271 (Optional for North America): A U.S.-based certification focused on battery packs used in light electric vehicles. Often requested by high-end brands and U.S. importers.
These certifications not only ensure the safe use and transportation of eBike batteries, but also build trust with buyers, regulators, and insurers. At JUNDA, all of our battery packs are tested and shipped with valid UN38.3 and MSDS documents, and we support CE, RoHS, and UL2271 upon request.
eBike battery packs are high-value components that require careful handling, proper maintenance, and responsible disposal to ensure long-term performance and environmental safety. Whether you’re a distributor, service center, or OEM brand, understanding how to maintain and recycle lithium-ion batteries is key to extending product life and building a sustainable supply chain.
Regular Charging: Avoid fully depleting the battery. Keep it between 20%–80% for everyday use to maximize cycle life.
Storage Tips: Store in a cool, dry environment (10–25°C). If not in use for more than 1 month, recharge to 50–60% every 2–3 months.
Temperature Control: Avoid exposure to extreme temperatures. High heat accelerates degradation; extreme cold reduces capacity.
Moisture Prevention: Never submerge battery packs. Always ensure housings and ports are properly sealed.
Connection Safety: Use correct chargers. Don’t bypass BMS protection, and avoid high current charging if not supported.
Physical Protection: Avoid impacts or drops. Cracked housings can cause internal damage and fire risk.
Cleaning: Wipe with a dry cloth. Never use water, chemicals, or abrasives to clean the battery shell or contacts.
Lithium-ion eBike batteries typically last 500–800 cycles depending on usage and care. Here’s how to handle end-of-life packs:
Performance Signs: Replace if voltage drops rapidly, charge times change, or capacity drops below 70%.
Safe Removal: Disconnect the battery fully, isolate terminals, and pack in an anti-static bag if shipping or discarding.
Recycling Partners: Work with certified lithium battery recycling services in your region (EU/US: follow WEEE, EPA, or local DG disposal laws).
Reuse for Second-Life Applications: Some modules can be repurposed in low-voltage storage or e-scooter applications.
A smart after-sales service plan not only extends battery value but also reduces waste. At JUNDA, we support:
Modular replacement programs (cells + BMS)
Local repair partner collaboration
Technical support for diagnostics and repair
End-of-life documentation and DG-certified packaging
Proper care = longer battery life = fewer replacements = better sustainability.
Want a recommended care sheet to include with your products? We can customize it for your brand.
