  • Automotive Grade LiFePO4 Battery

Sunray lithium iron batteries have excellent quality since they are manufactured by Automotive Grade LiFePO4 Cells with more stable performance, high energy density and greater power. Lithium iron phosphate batteries have CE certificate and pass UN 38.3, MSDS Test. With no acid in the battery, you’re able to safely mount in any position. This makes li-iron batteries perfect for solar home, RV, campers, golf cart, motor homes, off-grid applications.

  • 10-Year Lifetime

Sunray LiFePO4 Battery provides 2000-5000 cycles, which is more than 10 times to Lead Acid with 200~500 cycles. JITA LiFePO4 battery has a 10-year service life, three times longer than the Lead Acid’s 3-year lifetime. NOTICE: Please offer Address with house number, battery can NOT be put into PO BOX.

  • 1/3 Lightweight

This LiFePO4 Battery weighs only 60 lbs for one module, 30% lighter than that of lead acid batteries. It it an easier and more convenience choice for RV, Marine and Off-Grid Applications when mounting or moving.

  • 95% Efficiency

Sunray LiFePO4 battery’s flat discharge curve keeps above 12.8V for up to 95% of its capacity usage, offering astronomical boosts in run-time compared to only 50% in Lead Acid. Without memory effect, no matter what state the battery is, it can be used as soon as it is charged. As a solar energy storage cell, 12V Lithium Battery is a power supply for 12V household appliances, such as refrigerators, washing machines, TV, monitors and air conditioners.

  • BMS Protection & Delivery

This LiFePO4 battery has Built-In BMS to protect it from overcharge, over-discharge, over-current, low discharge rate and short circuit. Operating Temp: Charge: 0°C~50°C; Discharge: -20°C~60°C. Our battery is IP65 waterproof, letting you free from worrying about installing batteries indoors or outdoors.
