PowerTech Systems has rigorously selected and tested best-in-class Li-

5.12 kWh
thium Iron Phosphate cells that are assembled in this product, in order to (51.2V – 100Ah)
provide high lifespan and performance.
2.56 kWh
Lithium Iron Phosphate (LFP) is currently the best solution for storing energy, (51.2V – 50Ah)
because of its durability, its high security and its technical superiority compa-
red to other technologies on the market. BMS (Battery Management System) :
Embeds core intelligence of PowerRack system
The key points of PowerRack system : The main task of our Battery Management System (BMS) is to control
each vital element of battery: voltage and cell temperature, power sup-
