Description

The Speras S68 battery pack consists of two 18650 Li‑ion cells, each rated at 3400 mAh, connected in series. This configuration effectively doubles the voltage output (while keeping capacity equal to one cell), making it ideal for applications requiring higher voltage but stable capacity. It’s especially useful in high‑output flashlights, custom battery packs, or devices that benefit from elevated voltage. Because the cells are matched and pre-wired in series by the manufacturer, it simplifies installation and reduces mismatching risks compared to using separate cells in series yourself. This pack is ready to drop into compatible devices or integrate into custom power systems.
