Customer Reviews
i have a nice memory of our meeting in Shenzhn with Deligreen Mandy and a beautiful impression of your growing company.We both are straightforward and honest people and this is the most important value,so i am sure we can

—— Angelo from Italy

I am sure we can happily work together we should easily find a way to do.Money are important but aren't the most important part.

—— Angelo from Italy

Deligreen is the partner that i have replied one for years. Some other suppliers change sales quickly but Deligreen not.

—— Bonnett from USA

i have used the batteries for 9 years from Deligreen. Amazing!

—— Phil, LA

COVID19 made something more difficult. we need the balancers urgently.Thanks for the Deligreen team's effort. We receive the balancers on time and no delay for our project. Thank godness

Why Sodium ion battery

 

Lower limit voltage:Sodium battery can discharge to 0V without quanlity issue,but LiFePO4 battery might has problem under 2V.
 
Higher up voltage:Sodium ion batteries have a higher voltage platform 3.95V than LiFePO4 3.65V.
 
Better low-temperature performance:
 
Sodium ion electrolytes have better low-temperature conductivity, with a capacity retention rate of
over 80% at -20 ℃, while lithium iron phosphate batteries typically have a capacity retention rate of less than 60%.
 
Sodium ion batteries can be charged at -20 ℃. Lithium iron phosphate must be charged at temperatures above 0 ℃.No need to heat
and charge the battery.
 
Temperature and charging performance:
-20~0℃ :≤0.20C
0~45℃ :≤0.50C
 
Temperature and discharge properties:
-40~0℃ :≤0.50C
0~45℃ :≤0.50C
45~60℃:≤0.20C
 
High Safety
Sodium ions have very stable chemical properties, making them safer as home energy storage batteries
