Battery accessories and racks can be purchased through specialized industrial suppliers, B2B platforms like Alibaba/1688, and OEM manufacturers. Key products include 18650/21700 lithium battery racks, electric tool battery shells, and customizable ABS/PC plastic frames. Prices range from $0.25 for basic clips to $63 for V0 flame-retardant trays, with MOQs starting at 50 units for bulk orders.
Where to Find Industrial-Grade Battery Racks?
Specialized platforms like 1688.com offer customizable battery rack solutions for EVs and power tools. For instance, 21700 cell racks with 4×5 configurations (84V systems) feature laser-welded nickel strips and IP54 enclosures. Pro Tip: Verify rack dimensions against your battery module’s thermal expansion coefficient – mismatches cause warping in high-drain applications.

What Are Typical Costs for Battery Accessories?
Component pricing follows material complexity and order volume. Basic 18650 plastic trays cost $0.02/cell in 1,000+ quantities, while CNC-machined aluminum housings for power tools reach $18/unit. Mid-range options include:
| Product | Price | MOQ |
|---|---|---|
| 10-cell ABS shell | $3.80 | 50 |
| Fireproof battery tray | $14.45 | 100 |
Transitional orders between 500-2,000 units typically get 12-15% bulk discounts. Ever wonder why small orders cost more? Low-volume CNC setups waste 38% more material than mass production runs.
How to Select Compatible Accessories?
Match mechanical and electrical specifications precisely. A 21V tool battery shell requires 5-cell configurations with 18.5mm inter-cell spacing. Real-world example: Makita-style 15-cell racks use dual-stage injection molding for ±0.1mm tolerance – crucial for maintaining contact pressure in vibrating environments. Pro Tip: Request 3D CAD files from suppliers to verify fitment before ordering.

FAQs
Not recommended – varying thermal/mechanical properties between rack types create stress points. Always use identical series-connected modules.
Do battery racks include wiring harnesses?
Typically sold separately – specify required gauge (12AWG for >30A systems) and connector types (XT90/MPPT) when ordering.
