Lithium Polymer Lipo Rechargeable Battery Model KP 401020 3.7V 200mAH

Lithium Polymer Lipo Rechargeable Battery Model KP 401020 3.7V 200mAH 

The KP 401020 is a compact and ultra-lightweight 3.7V Lithium Polymer (Li-Po) rechargeable battery designed for miniature electronic devices that require efficient and stable power in a very small form factor. With a capacity of 200mAh, this cell is ideal for low-power systems that demand long standby time and reliable performance.

Its slim rectangular design (approx. 4mm × 10mm × 20mm) makes it perfect for tightly packed electronics such as wearables, IoT modules, portable sensors, and small gadgets. Thanks to its Li-Po chemistry, the KP 401020 offers a high energy-to-size ratio, low internal resistance, and a long rechargeable lifespan. When used with an optional PCM protection circuit, the battery is safeguarded against over-charge, over-discharge, and short-circuit conditions.
