Battery voltage, current, Max. Dimension etc.

Yes. Pictures and test report will be sent.

About 7 working days for samples, about 15-40 working days for mass production.

We are battery factory, has about 200 workers and 3 buildings with 15000㎡ area.

Absolutely, we fully support sample testing service for all li-po cells. You can place a small sample order first to check the size, voltage stability, connector matching and overall performance, which helps you avoid mass order risks before large batch cooperation.

This compact li-po cell fits a wide range of low-power miniature equipment. It is widely compatible with mini GPS trackers, portable beauty gear, wearable lightweight medical monitors, small smart toys and mini portable power backup modules, ideal for all tiny space-limited electronics.

Our li-po battery can support up to 500 complete charge and discharge cycles under standard 0.2C-0.5C discharge current. Compared with ordinary cheap miniature batteries on the US market, it has much longer service life and effectively cuts your long-term replacement cost.

We provide two mainstream connector options for customers to choose freely: JST and Molex. If your equipment requires exclusive customized connectors, our engineering team can also adjust the wiring terminals to match your device’s interface requirements.

Yes. All our lithium polymer batteries use industrial-grade carton packaging that complies fully with global air freight and ocean shipping regulations. Complete shipping compliance documents will be attached to each shipment to ensure smooth customs clearance when importing to the United States without detention or damage.

Customization is one of our core advantages. we can adjust the battery capacity, outer dimensions and nominal voltage according to your prototype or mass production hardware design demands.

All our lithium polymer batteries have passed CE, FCC and RoHS certification, which meet the mandatory safety standards for consumer electronics sold within the United States and North America. You can sell products equipped with our batteries on Amazon, Shopify and other mainstream US sales platforms without certification obstacles.

We offer full quality guarantee for all our li-po cells. If you receive defective or damaged batteries due to production or transit issues, please provide photos and test records to our customer service team. We will arrange free replacement or corresponding compensation to solve your trouble quickly.

The nominal voltage of this cell is 3.7V, and the maximum safe charging cutoff voltage is limited at 4.2V. This strict voltage protection design prevents overcharging, voltage surges and circuit burnout for your delicate miniature electronic devices.
