1.Sepecification Battery Type: Li-ion, LiFePO4, LTO （Selectable via mobile app) Compatible battery string range: Li-ion:4-8S / 8-20S | LiFePo4: 4-8S / 8-24S | LTO:6-8S / 8-24S Current Range: 200A/250A/300A/400A/500A Active Balance Current: 0.1A to 1A Bluetooth: Build-in B-P-Cable: 2AWG*2 200mm(250A) | 4AWG*2 200mm(300A) | 1AWG*2 200mm (400A&500A) Precharge function(Yes/No): Yes Parallel current limiting: Build-in Disconnection protection/wrong-wring protection(Yes/No): Yes Communication: UART *1 RS485*1 CAN*1 Software function: APP/PC Software /iOT cloud platform Sampling cable specifications: 24AWG 450mm NTC length: 250mm 2. Product Dimensions Product Size: L * W * H (mm) = 196*109*26mm,660g 3. How to select the BMS for your battery pack ? A. Battery Type Compatibility: This smart active balance BMS can suitable for LFP/NCM/ LTO. B. Number of Cells in Series (S) ：4-8S can work with Li-ion&LiFePo4 4S to 8S and LTO:6S to 8S | 8-24S can work with Li-ion 8S to 20S and LiFePo4<O:8S to 24S C.  Current Rating (Discharge and Charge Current)：For example, if your battery can discharge at 60A, your BMS must support at least 60A continuous discharge. Also you can add a margin (e.g., 20–30%) for safety. D. Balancing Functionality: Passive Balancing: Dissipates excess energy as heat OR Active Balancing: Transfers energy between cells. E: Communication Features : CAN, UART, Bluetooth Module, Wi-Fi Module(Optional). Packing List: Smart actice balance BMS *1 Sampling Cables *1 for 4-8S BMS ; Sampling Cables *2 for 8-24S BMS ; P- Cable *2 B- Cable *2 Screws *4 NTC cable *1 RS485/CAN 5Pin Cable *1 B+ Cable *1 Users Manual *1

• Active Balancing Technology: Utilizes energy transfer between cells instead of dissipating excess energy as heat (as in passive balancing).Transfers charge from higher-voltage cells to lower-voltage cells during charging or discharging cycles. Ensures faster and more efficient balancing, ideal for large-capacity packs or systems with significant cell voltage differences.
• Universal Compatibility: Works seamlessly with different battery chemistries such as Li-ion, LiFePO4, or LTO, provided the settings match.
• Wide Voltage Range Support: Can handle a broad range of total pack voltages, e.g.,Li-ion:4-8S/8-20S | LiFePo4: 4-8S/8-24S | LTO:6-8S/8-24S
• Built-in Bluetooth Function: The built-in Bluetooth and optional Wi-Fi module in DALY BMS provide versatile connectivity for real-time monitoring, system management, and remote alerts. This combination is ideal for applications ranging from personal use to industrial-scale setups.
• Accessories for Enhanced Functionality: Adding optional features like buzzer alarms, heating modules, key switches, LCD screens, and Wi-Fi modules makes the DALY Smart BMS a versatile choice for applications in EVs, outdoor equipment, solar systems, and cold environments. These enhancements provide better safety, user convenience, and performance reliability. Let me know if you'd like further assistance with selecting or configuring these components!
