FAQ:

ESS battery All in one Energy Storage System 5000kw

Q1. Can we put different LiFePO4 battery pack in series by ourself?

R1: You can buy big voltage directly from us. We suggest do not out them in series by yourself, it will hurt the cycle life of the

pack.

Q2. Does your battery pack include BMS? Can we use it for car?

R2: Yes, our battery pack include BMS, you can use it for low speed car only or aux. power for standard car. Do not use it for

standard car directly, that will need more complex design BMS for the pack.

Q3. What is your warranty?

R3: We offer 2 years warranty for all our battery pack. we ensure at least 2000 cycle life for the LiFePO4 battery pack, which

means, after 2000@80 percent DOD, there will still around 60 percent capacityt left. You can use it for at least 5 years for normal 1 time

charge and discharge everyday.

Q4. who are we?
We are based in Shenzhen, guangdong, China, start from 2004,sell to Africa(20.00 percent ),South Asia(15.00 percent ),South America(10.00 percent ),Eastern Asia(10.00 percent ),North America(5.00 percent ),Eastern Europe(5.00 percent ),Southeast Asia(5.00 percent ),Oceania(5.00 percent ),Mid East(5.00 percent ),Western Europe(5.00 percent ),Central America(5.00 percent ),Northern Europe(5.00 percent ),Southern Europe(5.00 percent ). There are total about 301-500 people in our office.

Q5. how can we guarantee quality?
Always a pre-production sample before mass production;
Always final Inspection before shipment;

Q6.what can you buy from us?
Construction Materials

Q7. why should you buy from us not from other suppliers?
