DIY Power Bank Case with Display and Type-C Input for 6×18650 Batteries

This DIY power bank case features a built-in display screen allowing easy monitoring of battery status and charging. It supports installation of six flat-head 18650 batteries (65mm length), providing high capacity for portable charging projects.

Designed for safe and reliable operation, the enclosure includes a motherboard with anti-chip and anti-burning protection circuits. The stylish outer shell comes in multiple colors for customization.

Only use flat-head 18650 batteries without protective plates. Batteries must have an internal resistance below 60 milliohms and a discharge rate above 1C for optimal performance.

After first installation, batteries require charging and activation via the enclosure's charger before output is available. Avoid using disassembled batteries frequently as it may degrade performance and user experience.

• Supports only flat-head 18650 batteries (65mm length)
• Internal resistance < 60 milliohms required
• Discharge current must exceed 1C
• Not compatible with battery modifications or welding

The motherboard protects against incorrect installation with an anti-chip function and prevents damage by integrating anti-burning components.

Though spring shrapnel forms one body, proper battery placement prevents short circuits to ensure safe and continuous usage. If burning occurs, correct reinstallation usually restores normal function.
