Product Description
The 18650 1S Battery Spacer Bracket is a premium, high-durability modular interlocking holder engineered for designing custom Lithium-Ion battery packs. Molded from flame-retardant, high-impact ABS/PC plastic, this single-cell spacer provides critical structural rigidity and excellent shock absorption for custom-built power setups. Its specialized slide-and-lock interlocking edge allows developers and assembly technicians to snap multiple brackets together seamlessly in any $X$–$Y$ axis configuration (such as 2S, 3S, 4P, or custom matrix shapes). By introducing a mandatory physical air gap between adjacent cells, it prevents dangerous heat accumulation and eliminates the risk of short-circuits caused by surface friction, fulfilling essential thermal management standards for professional, long-lasting battery packs.
Pinout / Layout Connections
This mechanical housing component acts as a structural guide without integrated electrical contacts:
Cylindrical Inner Core: Precision-molded 18.4mm diameter inner circular channel designed to snugly house a single standard 18650 cylindrical cell.
Interlocking Rails: Heavy-duty male and female dovetail tracks on all four external sides allowing multi-directional, snap-fit modular expansion.
Nickel Strip Channel: Recessed outer perimeter guide channels on the top and bottom faces optimized for the clean alignment, routing, and spot-welding of pure nickel connection strips.
Applications
Custom Battery Pack Building: Assembling high-voltage or high-capacity power banks for custom embedded systems and electric bikes.
Robotics & Automation: Creating ruggedized, vibration-proof onboard power packs for AGVs, mobile robots, and drones.
Renewable Energy Systems: Structuring stable battery arrays for small-scale DIY solar energy storage banks and off-grid setups.
Prototyping & Lab Testing: Providing secure physical alignment for 18650 cells during experimental load testing and thermal evaluations.
