Why LiFePO4 Lithium Battery
Longer Life Span
Up to 80% capacity for 3000 cycles in recommended conditions. The typical SLA has 300-400 cycles. ECO-WORTHY Lithium batteries last so long that the price per use is a fraction of traditional batteries.
Lightweight Champion
Our lithium battery is only 1/3 of the weight of a lead-acid battery, easy to move and install. It is an ideal choice for outdoor camping power supply and simple indoor installation.
High Efficiency
It provides up to 95% of their rated capacity while a lead-acid battery is usually limited to 50%. You get all the juice down to the last drop. It can support fast charging or solar panel charging.
Extremely Safe
LiFePO4 batteries are safest battery type available today. ECO-WORTHY lithium battery has a built-in Battery Management System(BMS), we can guarantee the safety and reliability of our batteries.
