Most energy storage systems, such as UPS and solar energy storage, use batteries from lead-acid battery  manufacturers, but more and more people are using lithium iron phosphate batteries (LiFePO4).

   The charging efficiency of lead-acid batteries is lower at 70%, while the charging efficiency of lithium iron phosphate batteries can exceed 80% or even 90%. Lead-acid batteries require more energy to charge, so a lot of energy is lost during charging. And when fast or partial charging can destroy lead-acid batteries, incorrect chargers or settings, and poor maintenance can shorten battery life.

   Compared with lead-acid batteries, the advantages of LiFePO4 are:

(1) Voltage stabilization time is longer

(2) No more flickering lights or jagged performance. While lead-acid batteries can be unreliable at 50% or less, the Grepow 12.8V LiFePO4 lead-acid replacement battery provides constant energy output down to 5% of its power.

(3) Fast charging

Lithium-ion batteries can be "fast" charged to 100% of their capacity. Typically, a LiFePo4 battery can be charged to 50% of its capacity in just 30 minutes. The Group lithium battery with fast charging technology can reach 100% capacity within 30 minutes; the highest charging efficiency of the charging rate can reach 3C.

(4) Intelligent multi-connected battery

LiFePO4 batteries are equipped with a battery management system (BMS) board where you can check the state of charge (SOC). What's more, the 12.8V modular LiFePo4 battery supports multiple connections, and batteries can be connected in series and parallel without an external BMS (maximum 4S10P; maximum parameters are 51.2V and 70Ah). You can also assemble batteries into different structures and shapes to fit the available space in the device.
