HIBMS Smart BMS Bluetooth 7S 120A Li-ion (LiFePo4) This BMS is for sale, brand new, never used, purchased for personal work. The HIBMS (or Hi-BMS) is a high-performance Smart Battery Management System specifically designed for 4S 12V LiFePO4 (Lithium Iron Phosphate) battery packs. It is often cited as being very similar in design and components to Daly BMS units, sometimes referred to as a "sister brand". Core Technical Specifications Battery Type: LiFePO4 (4 cells in series). Voltage: 12.8V nominal; 14.6V full charge. Continuous Discharge Current: 120A. Continuous Charge Current: Typically 60A. Peak Current: Can handle surges up to ~300A for short durations (starting loads). Protection: Includes overcharge, over-discharge, overcurrent, short circuit, and temperature protection (both high and low-temperature cutoff). Smart Features & App Control This unit includes an integrated Bluetooth module for real-time monitoring and parameter configuration. App Name: Search for "SMARTBMS" or "SMART BMS Pro" in the Google Play or iOS App Store. Default Passwords: Pairing: Typically 1234. Settings/Admin: Usually 123456 to modify protection parameters or capacity settings. Monitoring: The app displays individual cell voltages, total pack voltage, current (charge/discharge), temperature, and State of Charge (SOC). Wiring & Hardware Common Port: This model uses the same negative terminal (P-) for both charging and discharging. Balance Leads: It comes with a 5-wire balance harness (B0 through B4). B0 connects to the main negative, while B4 connects to the main positive of the 4S pack. Active Balancing: Features an internal balancing function (typically 30mA to 1A depending on the specific model variation) to keep cell voltages equal.
