Smart BMS 6S-16S 80A with Bluetooth UART 485 CAN

Advanced Multi-Chemistry Smart Battery Management System Architecture

This high-performance Smart Battery Management System (BMS) is engineered to monitor, protect, and optimize 6S to 16S energy storage and traction battery assemblies. Operating across a wide voltage input window, the processing unit features complete parameter adjustability via software, allowing hardware engineers and system integrators to tailor protection thresholds for Lithium-ion (NMC/NCA), Lithium Iron Phosphate (LiFePO4), and Lithium Titanate Oxide (LTO) cell chemistries. Constructed with ultra-low internal resistance power MOSFETs arranged in parallel and backed by a robust power distribution architecture, this board guarantees continuous current delivery, minimal voltage drop, and enhanced thermal endurance. It is designed to maximize overall battery pack cycle life and efficiency across high-demand applications including e-mobility platforms, off-grid solar energy storage systems (ESS), and heavy industrial equipment modules.

Galvanically Isolated Multi-Protocol Communications and Mobile Control

Equipped with a dedicated UART-to-Bluetooth transceiving module, the BMS streams low-latency real-time diagnostic telemetry directly to mobile devices via Android and iOS applications. Through the mobile control portal, users gain comprehensive visibility into overall pack voltage, individual series cell voltages, instantaneous charge and discharge currents, dual temperature channel telemetry, and precision State of Charge (SOC) calculated via an onboard high-accuracy bidirectional hall-effect/shunt coulometer. For demanding industrial control networks and smart home energy automation systems, the module integrates fully galvanically isolated RS485 (supporting standard Modbus-RTU) and isolated CAN 2.0B interfaces. These isolated physical layers prevent ground loops, electrical noise contamination, and high-voltage transients from affecting host controllers. Systems developers can easily utilize open communication protocols to bridge data directly to custom human-machine interfaces (HMI), external microcontrollers, PLC equipment, or PC-based supervisory control software.

Comprehensive Hardware Protection Circuitry and Heavy-Duty Thermal Design

Engineered to operate reliably in electrically noisy and harsh environmental conditions, the BMS incorporates multi-tiered hardware protection circuitry safeguarding against cell overcharge, overdischarge, overcurrent events, reverse polarity, and direct load short circuits. Dual high-precision external NTC thermistors continuously monitor cell temperature distributions to enforce dynamic charge and discharge cutoffs during over-temperature or under-temperature freezing events. When energy reserves drop below critical system cutoffs, the BMS transitions into an ultra-low-power deep sleep state, dropping baseline power consumption to sub-microamp levels to prevent irreversible cell starvation over extended storage cycles. An external physical hardware power switch connection provides immediate manual override control over the solid-state switching components. The entire circuit board assembly is coated with a high-grade conformal coating designed to withstand high humidity, airborne dust contamination, corrosive atmospheric gas, and electrostatic discharge (ESD). A heavy-duty extruded aluminum heat dissipation sink bonded to the power MOSFET stage allows the board to easily manage brief surge currents up to 2.5 times the sustained continuous operating rating without experiencing thermal runaway.

Precision Cell Balancing, Coulometric Tracking, and Cable Harness Specification

To eliminate individual cell capacity drift over thousands of charge and discharge cycles, the controller features an integrated passive balancing circuit delivering up to 60mA of per-cell balancing current. The automated balance routine activates dynamically when voltage differentials across cell series reach configurable deltas between 0.03V and 0.05V during the end-of-charge cycle. The unit comes fully equipped for immediate installation, featuring pre-soldered 14AWG high-flexibility flame-retardant silicone power leads (approximately 290mm in length) for high-current B- and C- bus connections. In addition, the package includes a 580mm multi-strand balance wiring harness equipped with color-coded, labeled insulation leads (B-, B1+ through B16+, and B+) for error-free wiring alignment and fast commissioning.

Versatile Industrial and E-Mobility Application Capabilities

Thanks to its configurable chemistry profiles and industrial-grade isolated comms stack, this smart BMS serves as a turnkey solution for scalable battery architecture design. Key deployment scenarios include custom light electric vehicle (LEV) drives, golf carts, marine propulsion banks, residential solar inverter battery storage arrays, unmanned aerial/ground vehicle ground power units, and remote telecom backup systems. The open register map allows direct integration with popular solar inverters and industrial automation hardware via the onboard CAN or RS485 communication ports.
