About This Project

Battery Pal provides a complete power solution for makers, integrating a Li‑ion/LiPo charger, cell protection, regulated voltage output, and a sophisticated fuel gauge that reports state‑of‑charge via serial or web interface. Its power‑path management allows the connected project to operate while the battery is charging, and selectable 3.3V or 5.1V outputs suit a wide range of electronics. The module ships with an NTC temperature adapter for JEITA‑compliant charging, and optional accessories like the Connector Breakout and Power Stick expand its usability. Estimated delivery is January 2027, with shipping and taxes added after the campaign via Kickstarter’s Pledge Manager.

Key Highlights

▸ Integrated fuel gauge with load, temperature and ageing compensation

▸ Selectable 3.3V or 5.1V regulated output with up to 2A current

Risks & Challenges

Component lead times, assembly yield, and shipping delays could affect the January 2027 delivery timeline; scaling production may reveal unforeseen manufacturing issues; reliance on a single supplier for certain parts poses supply risk.
