Dally BMS 4S12V 100A Battery Management System (BMS) for 12V 100Ah Battery Packs

Build your own reliable 12V 100Ah battery pack with the Dally BMS 4S12V 100A! This high-performance Battery Management System (BMS) provides comprehensive protection and monitoring for your 4S (four series) 12V lithium-ion battery pack, ensuring optimal safety and extended lifespan. Ideal for a wide range of applications, including electric vehicles, solar energy storage, and power tools, this BMS is designed for robustness and ease of use.

Key Features:

• High Discharge Current: A robust 100A continuous discharge current rating handles high power demands without compromising performance. This makes it suitable for applications requiring significant power draw.
• Precise Cell Balancing: Active cell balancing ensures all four cells remain at a similar voltage level, maximizing battery capacity and extending its lifespan. This prevents overcharging and undercharging of individual cells, a common cause of premature battery failure.
• Multiple Protection Features: This BMS provides crucial protection against:
  • Over-charging: Prevents damage from excessive charging voltage.
  • Over-discharging: Protects against deep discharge, which can severely damage lithium-ion batteries.
  • Over-current: Cuts off power in case of a short circuit or excessive current draw, preventing damage to the battery and connected devices.
  • Short-circuit Protection: Provides immediate protection against short circuits.
  • Temperature Protection: Monitors battery temperature and shuts down if it exceeds safe operating limits.
• Easy to Use: Designed with a simple wiring diagram and clear labeling for straightforward installation. No complicated programming or setup is required.
• Compact and Durable: Features a compact design for easy integration into your battery pack, with robust construction for reliable performance in various environments.
• Suitable for 18650, 21700, and other 18650-sized Lithium-ion Cells: This BMS is compatible with various lithium-ion cells of the specified size, providing flexibility in your battery pack construction. (Please ensure your cells are rated for at least 100A continuous discharge.)
• Low Internal Resistance: Minimizes energy loss during charging and discharging for optimal efficiency.
• Clear LED Indicators: Provides visual indication of the battery's charging and discharging status. (Specific indicators will be detailed in the included user manual).
