The SK80.5AH is a 3.7V 80500mAh lithium-polymer pouch cell manufactured by VATS Battery, an ISO9001-certified lithium battery maker based in Guangdong, China. Built on a compact customizable footprint, it combines a stable 3.7V nominal voltage with a true 80500mAh 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, which keeps batch-to-batch consistency high and makes the SK80.5AH 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.

Key Features
  • True Rated Capacity: Delivers a genuine 80500mAh 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.
Applications

Thanks to its slim, lightweight build and stable 3.7V output, the SK80.5AH fits a wide range of applications including:

  • Digital products
  • Bluetooth devices
  • GPS trackers
  • Power banks
  • Portable electronics
  • Bluetooth speakers and headsets
  • Fitness wearables and smart watches
  • Medical and healthcare instruments
  • Beauty and personal-care devices
  • IoT sensors
  • LED lighting
  • Toys

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

Packaging & Quality Assurance

Every SK80.5AH 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.

VATS Battery produces over 300,000 cells per day and exports to more than one hundred countries, offering a seven to twenty day lead time, free samples for evaluation, and a twelve-month warranty. If you need datasheets, samples or a custom specification, contact our sales team and we will match the right cell to your project and support you from prototype through mass production.

I’ve been using this 357090 3.7V 2500mAh lipo battery for a few weeks now, and I’m really satisfied with it. It is steady-quality rechargeable lithium polymer batteries that perfectly match the rated voltage and capacity. Output efficiency is great, which helps me save a lot of working time. Build quality feels solid too, no weird noises or faults during daily operation. Shipping was fast and the packaging was protective. For small-scale battery production and copying work, this is absolutely a practical and cost-effective pick. I’d definitely recommend it to fellow business partners and will consider reordering in the future.
