1. Core Advantages - Three Hidden Jobs of a Battery Tray
It weighs grams, not structure. The battery itself is the mass - the tray should add almost nothing to CG. Thin 3K carbon (sub-gram-class per small tray) holds position without moving your balance point.
It locks the battery so it can't shift. Strap slots cut to your width, plus anti-loose port design - the battery stays where your CG needs it through flight and landing bumps.
It sits between vibration and airframe. Trays and mounting plates act as a damping layer; we cut damper holes where your rubber dampers go, so motor vibration doesn't walk the battery loose.

3. Customization - Slot and Hole Layout to Your Battery
Send the battery dimensions and frame stack - we design the tray outline, strap slot position and mounting pattern.
Anti-loose details - port design and stop positions so the pack can't slide.
Damper integration - holes sized to your rubber dampers.
Sample then batch - and private-label packaging for your brand.
4. Company Advantages - Export-Friendly for Small Brands Too
No huge MOQ to start. Sample from 1 pc; grow into batch orders as your SKU sells.
Reorders repeat. Process locked after sample sign-off - your next batch matches.
Flexible shipping. Express for samples, sea freight for bulk.
5. FAQ
Q: How thin can the tray be? Down to 0.8 mm for light builds; heavy agricultural payloads need 2.5–4 mm. We recommend from your battery and payload weight.
Q: Can you cut custom strap slots? Yes - tell us the strap width and how the pack sits; we cut slot position and anti-loose details.
Q: Won't a thin tray flex? It flexes a little - that's the damping layer. Mounting holes are reinforced by the stack standoffs; the tray's job is holding, not spanning.
Q: Do you integrate dampers? We drill the holes; you supply or specify the rubber dampers.
