BMS-Equipped 12.8V LiFePO4 Battery Pack
12.8V Performance & Versatile Capacities
Voltage & Energy: Operates at 12.8V nominal (range: 10.8V–14.6V), available in capacities like 50Ah (0.64kWh), 100Ah (1.28kWh), 150Ah (1.92kWh), and 200Ah (2.56kWh). This flexibility suits diverse needs:
50Ah: Powers small devices (LED lights, phone chargers) for 2–3 days.
100Ah: Runs a 100W fridge for 12+ hours or 12V pumps for 50+ hours.
200Ah: Supports off-grid cabins with essentials (lights, fridge) through the night.
Stable Output: Maintains steady voltage under load, preventing drops that can damage sensitive electronics (e.g., solar controllers, inverters).
Integrated BMS for Safety & Longevity
Comprehensive Protection: The BMS acts as a "guardian," featuring:
Overcharge protection (shuts down at 14.6V) and over-discharge protection (cuts off below 10.8V) to prevent cell damage.
Overcurrent protection (50A–100A, depending on capacity) and short-circuit prevention, reducing fire risks.
Temperature regulation (-20°C to 60°C), with thermal shutdowns in extreme heat/cold.
Active Cell Balancing: Ensures uniform charge across 4 series LiFePO4 cells (3.2V each), maximizing capacity and avoiding uneven wear-critical for extending lifespan.
SOC Monitoring: Includes LED indicators or optional LCD displays to track State of Charge, eliminating guesswork about remaining power.
LiFePO4 Chemistry Advantages
Long Cycle Life: Supports 3,000–5,000 deep cycles (80% depth of discharge), outlasting lead-acid batteries by 6–10x (10–15 years vs. 2–3 years for lead-acid).
Lightweight & Compact: Weighs 70–80% less than lead-acid equivalents (e.g., 100Ah model: ~9kg vs. 25kg for lead-acid), fitting easily in tight spaces like RV cabinets or cabin storage.
Low Self-Discharge: Loses only 2–3% of charge monthly (vs. 10–15% for lead-acid), retaining energy for weeks-ideal for backup systems or seasonal use.

FAQ
Q: How does the ultrasonic cleaning process for removing contaminants work?
A: The ultrasonic cleaning process uses ultrasonic waves to remove contaminants. The object to be cleaned is placed in a cleaning solution. Ultrasonic transducers then generate high-frequency sound waves that are transmitted through the solution. These sound waves cause cavitation bubbles to form and collapse. The collapsing bubbles create intense local pressures and temperatures that dislodge and break up contaminants, such as dirt, grease, and rust. The ultrasonic cleaning can reach into small crevices and holes that are difficult to clean using traditional methods. In the jewelry industry, it can clean delicate gemstones and metal settings. In the medical field, it can clean surgical instruments, ensuring sterility.
