Power bank case for 21700 batteries with 8 LED PD elements, 100W DC 5-24V orange

The BQ-S87DC-100W is a solderless power bank enclosure designed for assembling a high-power portable power bank using 8 × 21700 lithium-ion batteries. The battery compartment uses a 2P4S configuration, meaning eight cells are arranged as two parallel groups connected in four series stages.

The enclosure is equipped with a powerful charging and power management board supporting USB Type-C bidirectional fast charging up to 100W. The Type-C port can be used both for charging the battery pack and for fast charging compatible devices.

The built-in DC output provides adjustable voltage from 3.3 to 24V, making the power bank suitable for powering various electronic equipment. The module also provides a USB fast-charging output up to 22.5W.

The front panel features a digital display showing battery and electrical parameters, two touch buttons for controlling the device and adjusting the DC output voltage, and bright LED illumination integrated into the transparent housing.

The enclosure is designed for solderless assembly and does not require spot welding. The battery compartment is intended for eight matching 21700 cells. The batteries are not included.
