Description
The Daly 4S 12V 100A LiFePO4 BMS is a professional-grade high-current protection module intended for 12.8V Lithium Iron Phosphate (LFP) battery packs. This heavy-duty BMS manages four cells in series and is specifically designed to handle high power needs, with a large 100A continuous discharge and charge capacity. Its durable, waterproof aluminum shell serves as an industrial-level safety barrier against overcharging, deep discharge, and short circuits. It is the clear choice for large-scale solar storage, RV house batteries, and electric propulsion systems.
Features
:- 100A High-Current Flow: This is one of the few tiny modules that can charge and discharge at 100A, making it perfect for high-power inverters.
- IP67 Waterproof and Dustproof: The gadget is internally sealed with high thermal conductivity silica gel, making it shock-resistant and moisture-proof.
- Smart Thermal Management: Contains an external NTC temperature sensor to monitor cell heat and prevent thermal runaway during long cycles.
- Passive Cell Balancing: Automatically maintains voltage homeostasis across all four cells to maximize the pack's overall capacity and lifespan.
- M6 Screw Terminals: Robust bolt-on terminals provide stable, low-resistance connections (P- and B-) for heavy-gauge cables.
- Precision Protection: Uses automotive-grade integrated circuits to detect overvoltages and undervoltages with millivolt accuracy.
Applications
:- Off-Grid Solar: Manages large 12V LFP banks for household energy storage and solar street lighting.
- RV & Marine: Use 12V home batteries in campervans, yachts, and boats to power refrigerators and inverters.
- Supports 12V to 230V/110V inverters with a power output of up to 1200W for emergency backup.
- Electric Trolling Motors: Offers a safe and dependable high-current discharge for electric boat motors.
- Portable Power Walls: A popular choice among DIY enthusiasts developing high-power portable energy stations.
Usage
:- B- Connection: Using a heavy-duty ring lug, connect the battery pack's primary negative terminal to the B- screw terminal.
- Balance Wire Sequence: Connect the thin white wires from Cell 1 Negative to Cell 4 Positive, verifying voltages with a multimeter before plugging into the BMS.
- P- Connection: Connect the system load negative and the charger negative to the P- screw terminals.
- Place the NTC temperature probe in the center of your battery pack (between cells) to ensure precise thermal monitoring.
- First Start: After all wiring is completed, some units require a brief charge (via a charger) to "wake up" the BMS.
