Full-Service Custom Battery Pack Manufacturer
We are a full-service custom battery manufacturer, offering comprehensive design and engineering solutions. Our team has extensive expertise in lithium-ion, lithium polymer, and LiFePO4 battery packs and assemblies. From initial concept to prototyping, testing, and large-scale manufacturing at our facilities in China, we collaborate closely with customers at every stage.
Many lithium and LiFePO4 battery packs require a Battery Management System (BMS) to ensure optimal performance. The BMS manages individual cells, balances them to improve efficiency, prevents overcharging and over-discharging, extends battery life, provides charge status (fuel gauge), and can even log the battery's operational history.
EGbatt’s technical team offers end-to-end support, including 3D modeling, hardware/enclosure design, and smart BMS development. We integrate advanced communication protocols such as I2C, SMBus, RS485, RS232, or CANBUS to meet specific project requirements.
