Advantages
High energy density for long run times.
Long lifespan: Up to 10+ years with proper maintenance.
Safe and stable: LiFePO₄ is thermally and chemically stable.
Maintenance-free: No need for water top-ups or balancing like lead-acid.
Fast charging: Can charge at higher currents safely.
Lightweight compared to lead-acid of similar capacity.
Typical Applications
Solar energy storage (off-grid or hybrid systems)
Electric vehicles (golf carts, forklifts, marine)
Backup power systems
Industrial equipment
RV or camper energy systems
🔌 Charger Considerations
You need a 48V lithium charger specifically designed for LiFePO₄ chemistry with:
Constant current/constant voltage (CC/CV) profile
Max voltage ~54.6V
Appropriate current rating (20A–100A depending on your system needs)
