Revolutionizing Power Storage: The 20KWH Lithium Ion Battery Journey

Client sourced a huge off-grid solar energy storage system INVENTORY recently. We helped him to get UPS and high-quality cells for low-temperature EFFICIENCY. It was the modular structure that form varieties in power system design. 

He also wanted to SOURCE small-size 150kw, 200kw, and 250 kw batteries. Small-size batteries were for ELECTRIC VEHICLES, so they need extra certifications. 

EV batteries have STRICT PROTECTION to avoid over-discharge and over-current. They also needed to have excellent cooling systems to prevent overheating. We looked for a 20KWH Lithium Ion Battery MANUFACTURER with UL 2580 certifications.

It was difficult at the start. We found a few suppliers with their own MANUFACTURING facilities. Our inspection staff visited their facilities and audited them. They check their SAFETY FEATURES and voltage with compatible systems. 

We countercheck the certifications and REQUIREMENTS for the EV model. After confirmation, he ordered a huge stock in different kWh capacities. We packed them in wooden racks with protective layers for convenient shipping. 

Customs cleared it in a short period due to our paperwork handling. He Launched his BUSINESS at his targeted MARKET. Low pricing with credible certifications got him a lot of sales. The BUSINESS got a huge revenue from EV battery sales.
