🧠 Built for Safety & Efficiency
Each cell and series is individually tested before assembly.
The integrated Battery Management System (BMS) ensures:
Overcharge / Over-discharge protection
Cell balancing
Thermal stability under heavy load
Solid copper and nickel busbars are precision spot-welded to each cell for maximum conductivity and reliability. This overbuilt design means smoother power delivery, cooler operation, and longer battery life.
