Import 3s -32s 10a-500a Bluetooth Bms — Buy in wholesale FOB from Supplier in China

The 3S -32S 10A-500A Bluetooth BMS from Benbv Trade Co., Ltd. is a programmable battery management system designed for lithium iron phosphate and lithium-ion battery packs, configurable from 3 to 32 series cells with continuous discharge current ratings spanning 10A to 500A. The unit integrates Bluetooth wireless monitoring, RS485 serial communication, and CAN bus protocol support, enabling real-time state-of-charge tracking and remote diagnostics through compatible Android or iOS applications. Its semiconductor architecture employs MOSFET switching and integrated IC control for active cell balancing and multi-layer fault protection.

Constructed on a PCB composite substrate, this BMS utilises precision MOSFET arrays and dedicated IC chips for voltage sensing, temperature monitoring, and current regulation. The overcharge protection threshold, cutoff voltage, and balancing current are factory-programmable parameters typical of smart BMS units in this class, though buyers should confirm the exact voltage accuracy (standard: ±0.05V per cell typical) and balancing current capacity with Benbv Trade directly. The RS485 and CAN bus interfaces comply with standard industrial communication protocols, allowing integration with inverter systems, energy storage controllers, and vehicle management systems.

This BMS targets OEM manufacturers of electric vehicles, solar energy storage systems, uninterruptible power supplies, and industrial backup power installations where scalable, high-current battery protection is required. Importers sourcing for the European or North American markets should verify compliance with relevant electromagnetic compatibility directives and safety standards. The 10A to 500A current range accommodates applications from lightweight portable power stations to heavy-duty traction battery packs, with the higher current variants typically employing parallel MOSFET configurations and enhanced thermal management.

Benbv Trade Co., Ltd. is based in Changsha, Hunan Province, China, with a registered address at Building 8, Niulijiayuan. The supplier holds a Harbor trust tier on the sourcing platform, indicating a verified business licence and operational status, though its response rate is recorded at 0.00% with an average response time of zero hours, suggesting either a newly listed profile or inactive enquiry management. Buyers should test direct communication through the listed contact channels before committing to orders.

The company's product focus centres on battery management systems with integrated communication capabilities for lithium-based energy storage. No verified factory size, annual revenue, export history, or client references are stated in the available profile data. The supplier's address places it within Changsha's emerging electronics manufacturing corridor, though this does not confer any specific quality or capacity guarantees. Importers are advised to conduct independent verification of production capabilities, quality management systems, and past export performance before placing bulk orders.
