Discover, 6.65kWh,51.2VDC AES Lithium Ion Battery, Canbus, 12-48-6650

Discover Advanced Energy (AES) batteries allow for equipment design and functionality improvements and deliver productivity gains through enhanced cycling, charge time and weight reductions in stationary and mobile applications. Dramatic improvements in cycle life and charge efficiency combined
with zero maintenance requirements provide the end user with significant cost of ownership savings.


  • Efficient & Fast Charging - Discover AES batteries are 15% more efficient than lead acid batteries, allowing for reduced charge times and greater utilization of renewable energy sources. Deliver >95% of their capacity at high and stable voltages, increasing equipment performance and reducing motor fatigue.
  • Partial State of Charge (SOC) & Weight Efficient - Discover AES batteries will never suffer negative effects from partial SOC. Systems are 1/3 the weight of their lead acid battery equivalent.
  • Battery Management System - Integrated Battery Management System to prevent abuse outside of current, voltage and temperature limits.
