Our batteries focus on improving energy density, fast-charging
capabilities, safety through new materials, and environmentally
friendly, recyclable processes to meet diverse power demands.

3.7V Battery

3.7V batteries include single-cell lithium-ion
(Li-ion) and lithium polymer (Li-Po) types. Li-ion batteries have a nominal voltage of 3.7V, charge up to 4.2V, and discharge to about 3.0V. Li-Po batteries offer higher energy density and customizable shapes. They are lightweight, have high energy density, long cycle life, and are widely used in smart wearables and portable LED devices.

5V Battery

5V batteries are typically regulated outputs
from multiple lithium cells or USB-powered
sources.They are lightweight, convenient,
and used for low-power USB devices, toys,
and small tools.

7.4V Battery

7,4V batteries consist of two lithium cells in
series, with a nominal voltage of 7.4V and a full
charge at 8,4V.They suit medium-power devices often equipped with protection circuits, and are used in drones, remote-controlled cars, cameras photography lights, and robotic devices.

12V Battery

12V batteries include lead-acid, lithium packs and nickel-metalhydrde types,ihey suppor
higher power devices with longer service life and are used in automotive starters, UPS
systems, monitoring devices, and power tools

Other Voltage Battery

1.2V/1.5V(AA/AAA): Used in clocks, remotes, and toys
9V:ldealtorsmoke detectors and instruments.
24V/48V+: Found in e-bikes, industrial equipment, and energy storage systems.

BATTERY CAPACITY INTRODUCTION

The different battery capacities (mAh) represent the amount of
power the battery can store and affect how long the device can
be used.

2200mAh Battery Capacity

For temporary emergency and light use. It has a small capacity for low-power small devices such as remote controls, Bluetooth headsets, and other low-power devices with battery life available for several hours.

3000mAh Battery Capacity

Use it for daily commuting, light entertainment, and office work. It has a medium capacity for 6-12 hours of battery life for smartphones, Bluetooth stereos, and other electronic devices.

5000mAh Battery Capacity

Used for outdoor activities, heavy use, traveling, and other scenarios. It has a large capacity, long battery life, suitable for high-endurance cell phones, tablets, mobile power, and other devices, with 1-2 days of battery life.

10000mAh Battery Capacity

Used for outdoor traveling, emergency power supply, multi-device charging, and other scenarios. It has a large capacity, suitable for high power-consuming devices, supports multiple charging, and long battery life.

Battery shape and size can be flexibly customized, widely used in consumer electronics,industrial equipment, energy storage systems and special equipmentand other fields, providing efficient power supply solutions.

Battery shape

————————————————————————

Common battery shapes include cylindrical batteries and flat square batteries. Button batteries, square batteries, as well as we can customize the shape according to the demand for shaped batteries to flexibly adapt to the design of special equipment.

Battery size

————————————————————————

Standard sizes, such as AAA, AA, 18650, are suitable for most general-purpose devices; in addition, we can customize the size, thickness, and volume to fit special devices.
