▲Dear customer, the 66160 battery you purchased is an old battery from Yinlong, not brand new. This battery has been discontinued and is available in the market as it was removed from a car. Although there may be some flaws in its appearance, it does not affect your use. The voltage and capacity of the battery have also undergone strict testing before shipment, so you can use it with confidence.

▲Good charging and discharging ability: high power discharge and fast charging ability

▲Long cycle life: The cycle life is 25,000 cycles (80% DOD), which is more than 10 times that of traditional lithium-ion batteries.

▲Ultra-low temperature performance: -30℃ is good at low temperature, working temperature range is -50℃～+65℃.

▲Good safety performance: There is almost no SEI film on the lithium titanate anode to prevent the battery from overheating and causing a fire.

▲Lithium titanate battery has the characteristics of long life, good low temperature performance, safe and fast charging and discharging, and can be used for peak and valley energy storage, wind energy, solar energy and other energy storage.
