G2000 3.7V 600000mAh Lithium Polymer Battery Rechargeable Grade A Cell Long Cycle Life

The G2000 3.7V 600000mAh Lithium Polymer Battery is a rechargeable lithium-polymer pouch cell engineered by VATS Battery for reliable, long-lasting power in modern electronic devices. Built on a compact, customizable footprint, it combines a stable 3.7V nominal voltage with a true 600000mAh capacity — so portable devices run longer on a single charge without adding bulk.

Each cell is produced on automated lines and individually screened for capacity, voltage, and internal resistance before shipment. This keeps batch-to-batch consistency high and makes the G2000 a dependable drop-in power source for OEM and ODM programmes. Because the chemistry, dimensions, and protection circuit can all be customized, engineers can either select this standard model or ask us to develop a bespoke cell around a specific power, footprint, and cost target.

• True Rated Capacity: Delivers a genuine 600000mAh at 3.7V, verified by capacity, voltage, and internal-resistance testing on every production lot.
• Stable Output: A flat discharge curve holds close to 3.7V, protecting sensitive circuits and extending usable runtime.
• Long Cycle Life: Rated for more than 500 charge–discharge cycles with excellent capacity retention.
• Certified Safety: Compliant with IEC62133 / UL / CE / CB / KC / UN38.3 / MSDS, with built-in protection against over-charge, over-discharge, over-current, and short circuit.
• Flexible Customization: Size, capacity, voltage, connector, wire length, and PCM can be tailored to your design; OEM and ODM are both welcome.
• Ready to Integrate: Supplied with JST / Molex (optional) so the cell can drop straight into your assembly line.

Thanks to its slim, lightweight build and stable 3.7V output, the G2000 fits a wide range of applications including digital products, Bluetooth devices, GPS trackers, power banks, and portable electronics. Typical end products are:

• Bluetooth speakers and headsets
• Fitness wearables and smart watches
• GPS trackers
• Medical and healthcare instruments
• Beauty and personal-care devices
• IoT sensors
• LED lighting
• Toys and portable power banks

Its customizable connector and protection circuit simplify integration, reducing assembly time and supporting both prototyping and high-volume mass production.

Every G2000 is packed in industrial cartons with anti-static trays and shock-absorbing material that meet international air and sea shipping standards, protecting the cells throughout transport.
