Choose 600A or 800A continuous current options for 8–24S lithium battery packs, with smart communication support for monitoring and tuning. A modular internal layout combines smart connectivity with optional brake-resistor control and a sealed, glue-injection construction. Key specifications are summarized for quick selection, including charging/discharge current, overcurrent protection, and passive balancing settings. Cell protection thresholds and temperature limits are configurable by chemistry, helping tailor behavior to Li-ion, LiFePO4, or LTO packs. High surge handling supports demanding loads with peak and short-duration extreme overcurrent capabilities. Thick copper conductors and reinforced power components are used to support ultra-high current flow with lower losses. A practical fit for heavy-duty traction and industrial vehicles where sustained current and reliability matter most. A compact MOS-based design reduces extra hardware needs while keeping system configuration accessible through smart tools. Multiple interfaces simplify integration with displays, controllers, and optional braking energy absorption hardware. Manage parameters from a mobile app or PC software, with UART/RS485/CAN communication options depending on configuration. Remote management via DALY Cloud supports centralized monitoring and batch management when paired with a wireless communication module. Glue-injection potting helps protect internal electronics against splashes, dust, vibration, and oxidation in tougher environments. Active fan cooling and an aluminum heat sink help move heat away efficiently during high-current charge and discharge. Included accessories support installation and basic connectivity; confirm the exact bundle contents for the selected option. Expand system monitoring with optional communication cables, wireless modules, and display panels based on your build requirements. Follow the recommended sampling-wire order and terminal connections to complete installation and enable optional brake-resistor functionality. Engineering teams and test facilities support continual improvements in high-current BMS design and validation. DALY uses an intelligent production base and hands-on quality control during BMS manufacturing. Orders typically ship within 3–7 days after purchase, with no shipments on Sundays, and the product includes a one-year warranty under normal use.
