Mecer second life LIFEPO4 Lithium Battery 12.8V 200Ah, 1500 charging cycles, Can use up to 4 batteries in series with the built in BMS (Battery Management System) 1900Whr usable energy @ 80% Depth of Discharge.

Benefits of Lithium solar storage / power backup batteries.

• Lithium Batteries have a longer life span than Lead Acid Battery
• Lithium Batteries have deeper discharge cycles than Lead Acid Battery
• Lithium Batteries stay above 12.5V at 90% discharge
• Lithium batteries are lighter for the same capacity (about 33% of the weight of Lead Acid)
