This set features a staggered (offset) layout instead of the traditional square grid. By nesting the rows together, these holders significantly reduce the overall dimensions of the battery pack, making them ideal for projects where space is at a premium (like inside e-bike frames or portable tubes).

The Set Includes:

• 3-Cell Holder: Triangular configuration (perfect for minimal packs).
• 5-Cell Holder: 2-row offset (3+2 layout).
• 7-Cell Holder: 2-row offset (4+3 layout).
• 9-Cell Holder: 2-row offset (5+4 layout).

Key Features:

• Space Efficient: The nested "honeycomb" packing is much more compact than standard square grids.
• Rigid Structure: The triangular geometry creates a naturally stable block.
• Versatile: Designed specifically for odd-numbered cell configurations often needed in custom voltages.

Printing Instructions:

• Material: PETG, ABS, or ASA are strongly recommended. PLA may deform if the cells get warm under load.
• Supports: None required.
• Walls: 2-3 perimeters for strength.
