The cost and performance of lithium batteries continuously improve, the power density makes the consoles significantly smaller and compact. The round trip process, DC-to-storage-to-DC energy efficiency of the storage bank, or the fraction of energy put into the storage that can be retrieved, is one of the most important characteristics. That means less than 5% of your stored energy is lost in the conversion process. 


  • Extremely high efficiency, round trip efficiency 95%
  • Very low standby consumption less than 0.5Watt
  • Higher discharge and starting current compared to lead-acid
  • Energy density 100-200Wh/kg
  • Power density 1500-2000W/kg
  • Recharge time 1hour to 100%
  • Operating temperature from 0°C to 45°C 


  • We offer 48V50Ah (CATL)  batteries with sophisticated & reliable BMS.  
  • You can connect them in parallel to make 2.4kwh to 120kWh system.
