🔋 High Capacity 18650 Battery Case (Modular)

A robust chassis design for assembling your own Lithium-Ion battery packs. Perfect for solar, outdoor or DIY power stations.

🛠️ Design Features:

  • Compatibility : Designed for 18650 cells (here configured in 3S20P, but adaptable).

  • Assembly : Secure closure with M3 inserts and M3x20 screws for maximum durability

  • Wiring : Optimized passages for thick silicone cable (up to 2.5mm²).

  • Robustness : Rigid structure that perfectly maintains cell alignment for spot welding.

💡 Implementation Tips :

  • Material : PETG, ABS or ASA recommended (for thermal resistance).

  • Safety : The installation of a BMS is mandatory for charge/discharge management.

  • Finishing : Prepare a soldering iron for hot insertion of M3 inserts.

Note : This project is a mechanical base. The final capacity (Ah) will depend on the quality of the cells you choose to install!
