About Lithium Batteries

Lithium Batteries for Solar & Backup

Power your solar, off-grid, or backup system with high-performance lithium batteries from PES Supply. Lithium batteries offer dramatically longer cycle life, lighter weight, and deeper discharge capability compared to lead-acid—making them the smart choice for energy storage. Shop brands including EG4, Fortress Power, BYD, SONNEN, Victron Energy, and more.

Lithium Battery Advantages

  • 3,000-6,000+ cycles vs. 500 for lead-acid
  • 80% depth of discharge safe and routine
  • Lighter and smaller for equivalent capacity
  • Built-in BMS for cell protection and balancing
  • Flat discharge curve maintains voltage longer

Lithium batteries include both LiFePO4 (lithium iron phosphate) and NMC chemistries. LiFePO4 offers the best safety and longevity, while NMC provides higher energy density. Our team can help you choose the right chemistry, voltage, and capacity for your inverter and application.
