Overview: DALY Smart BMS for LiFePO4 Battery 150A
The DALY Smart BMS for LiFePO4 Battery 150A is a professional battery management solution designed to protect, monitor, and balance lithium iron phosphate (LiFePO4) packs. Built for reliability and precise cell care, this BMS is suited to electric vehicles, solar energy storage, portable power stations, and demanding DIY projects.
Key Features
- 150 A Continuous Current: Supports sustained currents up to 150 A, with a 200 A 10 second peak for brief surges.
- Precision Passive Cell Balancing: 100 mA balancing current per cell helps equalize voltages and prevent premature aging.
- Comprehensive Protection Suite: Overcharge, over-discharge, over-current, short-circuit, and over-temperature protection keep cells safe.
- CAN and UART Communication: CAN bus and UART (TTL) output live data for pack voltage, individual cell voltages, current, and temperature to displays or controllers.
- Low Standby Consumption: Idle current under 2 mA prevents unnecessary drain when the pack is not in use.
- Compact, Mountable PCB: 80 × 50 × 8 mm with four M3 mounting holes for straightforward installation in tight enclosures.
Benefits of Installing a DALY Smart BMS
- Improved Safety: Rapid response to over-current and short-circuit events reduces risk of damage and fire.
- Longer Battery Life: Consistent balancing and correct charge/discharge limits prevent weak cells from aging the pack prematurely.
- Reliable Performance: Maintain each cell within safe voltage and temperature ranges for predictable pack behavior under load.
- Easy Integration: Clear wiring labels and common communication protocols make adding monitoring to your system simple.

How the BMS Protects Your Pack
The DALY Smart BMS continuously monitors each cell and the overall pack. It will stop charging if any cell exceeds safe voltage, disconnect the load if cells fall below safe voltage, and react instantly to over-current or short-circuit conditions. Temperature monitoring pauses charge or discharge when cells exceed safe limits. Passive balancing reduces voltage differences between cells to maximize usable capacity and cycle life.
Installation Guide
- Mount the BMS: Secure the board using four M3 screws inside the battery enclosure.
- Connect Cell Leads: Attach balance wires to the labeled cell ports for cells 1 to 20.
- Hook Up Main Leads: Connect pack positive to B+ and pack negative to B- terminals.
- Connect Communications (Optional): Plug CAN or UART cables into your controller or display for real-time telemetry.
- Power On and Test: Apply a small charge or load. Solid green LEDs indicate balanced, healthy cells.
Applications
- Electric vehicles: e-bikes, e-scooters, golf carts, small EV conversions
