DALY “Mini-Black” Smart Series-Compatible BMS: Empowering Low-Speed EVs with Flexible Energy Management

As the global low-speed electric vehicle (EV) market booms—covering e-scooters, e-tricycles, and low-speed quadricycles—demand for flexible Battery Management Systems (BMS) is surging. DALY’s newly launched "Mini-Black" smart series-compatible BMS addresses this need, supporting 4~24S configurations, 12V-84V voltage ranges, and 30-200A continuous current, making it a versatile solution for low-speed mobility scenarios.

A key highlight is its smart series compatibility, which solves inventory challenges for B2B clients like PACK manufacturers and repairers. Unlike traditional BMS that require stock for fixed cell series, the "Mini-Black" works with lithium-ion (Li-ion) and lithium iron phosphate (LFP) batteries, adapting to 7-17S/7-24S setups. This cuts inventory costs by 50% and enables quick responses to new orders without re-purchasing. It also auto-detects cell series on first power-up, eliminating manual calibration.

For user-friendly management, the BMS integrates Bluetooth and a mobile app, allowing real-time monitoring of voltage, current, and charging status. Via DALY’s IoT cloud platform, businesses can remotely manage multiple BMS units—adjusting parameters and troubleshooting issues—to boost after-sales efficiency by over 30%. Additionally, it supports "one-wire communication" for mainstream EV brands like Ninebot, Niu, and Tailg, enabling plug-and-play use for DIY enthusiasts with accurate dashboard displays.

 
Hardware-wise, the "Mini-Black" uses high-quality components with 1A parallel current limiting, supporting 22000uF capacitor pre-charging. Customizable secondary protection fuses cater to heavy-duty needs. Backed by DALY’s 4 R&D centers and 20 million annual production capacity, it suits both small-scale repairs and large-volume PACK integration, standing out as a cost-effective BMS for low-speed EVs.
