Epsilon SB12V1200Wh-M

The Epsilon is a drop-in lead acid replacement, with all the benefits of Lithium Iron Phosphate. It has superior weight reduction, enormous energy reserves and stable voltage even at extreme loads.


  • Traction battery
  • Lithium Iron Phosphate (LiFePO4)
  • Most safe lithium technology today
  • Superior abuse tolerance
  • Integrated BMS (Battery Management System)
  • Up to 95mm2 wire connection per terminal
  • Integrated short circuit protection
  • CAN / LIN / Bluetooth interface for battery monitoring
  • Battery monitoring/ history storage
  • Adaptive cell balancing
  • Battery monitor app for iOS and Android 
  • This battery is for 12V installation, parallel connection possible (do not put in series)


  • High capacity (can power coffee machines, airco and other devices that could not be powered from traditional batteries)
  • Low weight (-20kg compared to lead acid)
  • High cycle count, up to 5000 cycles
  • Low maintenance
  • One on One replaceable with AGM/GEL lead acid batteries
  • High discharge current, 200A continious, 350A pulse (30s)
  • >96% efficiency means more efficient (solar) charging and using almost all available energy


Super B batteries are based on Lithium Iron Phosphate technology (LiFePO4). This is the safest Lithium technology available today. On top of that our bespoke casing and electronics further increase safety and durability.
