How many cycles can a 3.8V HV battery provide?

500 cycles or more with at least 80 percent capacity retention under standard test conditions.

Can HV LiPo batteries be used in high-drain applications?

Yes. HV LiPo batteries are suitable for high-drain applications due to improved voltage stability, reduced voltage sag, and enhanced power delivery capability under load.

Do HV LiPo batteries require special protection circuits (PCM/BMS)?

Yes. HV LiPo batteries should be paired with compatible protection circuits that support 4.35V charge thresholds to ensure safe voltage control, overcharge protection, and long-term stability.

Can I use my existing 3.7V charger to charge a 3.8V HV battery?

No. A 3.7V charger cuts off at 4.20V, which will only partially charge an HV battery. Always use a 4.35V specific charger.

Key features

Maximizes usable energy per cycle, delivering higher energy density than standard 3.7V LiPo batteries and extending device runtime within the same footprint.

Engineered with advanced HV chemistry that minimizes voltage sag under peak loads, ensuring stable power output for high-drain electronics and preventing performance drops during operation.

Built with a low self-discharge rate even under high-voltage storage conditions, maintaining charge longer and reducing maintenance requirements for intermittent-use devices.

Supports a 3.0V to 4.35V operating range, enabling higher usable capacity per cycle, improving system efficiency, and reducing recharge frequency.

Maintains a flatter discharge curve, ensuring stable and consistent performance throughout the entire usage cycle instead of rapid late-stage power decline.

Suitable for IoT devices, wearables, medical electronics, and industrial handhelds where space is limited but long-lasting and stable power is required.

Compliant with air and sea transport regulations for lithium batteries, ensuring safe international shipment and reliable global deployment.

Flexible customization, including capacity, dimensions, connector type, and wire length, is supported by factory-direct production with strict batch consistency and full traceability.

Product Q&A

Q:Can I get samples of lithium batteries before placing a bulk order?

Yes, many suppliers offer samples of lithium batteries for testing and evaluation purposes. However, there are costs associated with obtaining samples, including sample fees and freight charges.

Q:What is the delivery time after placing an order with Ufine Battery?

Normally, it takes 10 to 12 days for air transportation, and more than 45 days for sea transportation.

Q:How long does it take to make a sample of a custom battery?

It takes 1~3 days to make regular samples, and 7~10 days to make handmade samples. The time required increases with the number of samples.

Q:What is the difference between a high-voltage LiPo battery and a standard 3.7V LiPo battery?

An HV LiPo battery charges to 4.35V, while a standard 3.7V LiPo charges to 4.20V. The higher voltage allows HV cells to deliver more usable energy, longer runtime, and better voltage stability in the same size.

Q:What is the main benefit of HV LiPo in system design?

The main benefit is higher energy output at the same size, which allows designers to reduce battery volume or extend device runtime without changing product form factor.
