Overview: DALY Smart BMS for LiFePO4 Battery 100A
The DALY Smart BMS for Lithium Iron Phosphate (LiFePO4) Battery 100A is a high-performance battery management system engineered to protect, balance, and monitor LiFePO4 packs. Built for applications that demand reliable battery health and safe operation, this smart BMS is ideal for solar energy banks, electric bicycles, off-grid systems, and DIY EV projects.
Key Features
- 100A Continuous Current: Handles sustained currents up to 100 A with a 150 A peak for 10 seconds.
- Cell Balancing: Active balancing (approx. 80 mA per cell) keeps cell voltages equal to prevent premature cell wear.
- Comprehensive Protection: Overcharge, over-discharge, over-current, short-circuit, and over-temperature safeguards preserve pack integrity.
- Communication Ports: CAN bus and UART (TTL) outputs enable real-time monitoring, logging, and integration with BMS displays or controllers.
- Low Quiescent Current: ≤ 2 mA standby draw to avoid draining the pack when idle.
- Compact and Lightweight: PCB size 80 × 50 × 8 mm, weight 90 g, with four M3 mounting holes for secure installation.
Protection Functions
- Overcharge detection and cutoff to prevent cell overvoltage.
- Over-discharge cutoff to protect weak cells and avoid sudden power loss.
- Short-circuit and over-current shutdown for fault isolation.
- Temperature monitoring with automatic charge or discharge halt when cells exceed safe limits.

- Peak Current (10 s): 150 A.
- Cell Count: 4S to 20S LiFePO4.
- Balance Current: Approximately 80 mA per cell.
- Protection Functions: Overcharge, over-discharge, over-current, short-circuit, over-temperature.
- Communication: CAN bus and UART (TTL).
- Operating Temperature: -20 °C to +60 °C.
- PCB Size: 80 × 50 × 8 mm.
- Weight: 90 g.
- Mounting: Four M3 screw holes.
Benefits of Using the DALY Smart BMS with LiFePO4 Packs
- Reliable Battery Protection: Continuous monitoring of voltage and temperature prevents cell damage.
- Extended Pack Life: Regular cell balancing prevents weaker cells from failing early and evens out cycle life.
- Efficient Management: Low idle draw preserves stored energy over long standby periods.
- Versatile Applications: Suitable for home energy storage, e-bikes, scooters, off-grid cabins, boats, RVs, and portable power stations.
- Easy Installation: Clear terminal labeling and four mounting holes make installation fast for DIY and professional builds.
How the DALY Smart BMS Keeps Your Pack Safe
The BMS continuously measures each cell group and uses active balancing to equalize voltages during charging. When a cell reaches an unsafe voltage or temperature, the BMS disconnects charge or discharge paths to prevent damage. For sudden faults like short circuits or extreme over-current, the BMS reacts quickly to protect the pack and connected equipment. CAN and UART ports provide real-time status and fault codes so you can monitor performance remotely.
Installation Guide
- Mount the BMS: Secure the PCB inside the battery enclosure using four M3 screws on a flat surface.
- Connect Balance Leads: Attach each cell balance wire to the corresponding balance input from cell 1 up to cell 20 as required by your pack.
- Attach Main Wires: Connect the pack positive and negative leads to the B+ and B- terminals.
- Connect Communication (Optional): Plug CAN or UART cables into your display or controller for monitoring.
- Power On and Test: Apply a charge or load. LEDs will indicate status; green indicates cells are balanced, red indicates a fault.
Applications
- Home solar energy storage and battery banks.
- Electric bicycles, scooters, and light electric vehicles.
- Off-grid power systems for cabins, boats, and RVs.
- DIY electric vehicle projects like golf carts and trikes.
- Portable power stations for camping and emergency backup.
