Custom Rechargeable Lithium Battery for Bluetooth Speakers and Portable Audio Devices

Our rechargeable lithium battery packs are customized to fit Bluetooth speakers, portable audio devices, voice amplifiers, and small sound systems that need a consistent power supply, long operating time, and easy installation. The voltage, capacity, size, cell layout, connector, wire length, polarity, protection circuit, and outer packaging can be tailored to the structure and performance needs of each product. The battery pack may contain overcharge, over-discharge, overcurrent, short-circuit, and temperature protection depending on the application to enable safe and reliable operation. Good lithium-ion or lithium polymer cells offer a viable combination of energy density, lightweight construction, and cycle performance. The sample development, battery compartment matching, connector selection, and electrical compatibility testing are supported by our engineering team before mass production. The applications of these customized battery solutions include new speaker applications, replacement batteries, product upgrades, and OEM or ODM manufacturing for audio brands, electronics developers, and professional sound-equipment suppliers.
