Its long life and high power density offer total value for money. The CelPak is approximately 50% more efficient resulting into better milage and higher profits per ride. Fast chargin enables maximized drive time throughout the day. It's economical, pocket friendly and optimally suited for your E-Rickshaws.

  1. Lithium Advantage
  2. Fast Charging
  3. Zero Pollution
  4. Longer Battery Life
  5. Non Flammable
  6. Non Explosive

Regarding the lithium cells we also stand out from the usual market standard - lithium-iron phosphate (LiFePO4). Instead, we use lithium iron Manganese phosphate (LiFeMnPO4). The doping with Manganese will increase the cell's life expectancy and performance. The conceptual design and chemistry of our Li-cells renders them intrinsically safe, this means in case of a problem the cells can not catch fire. By the way, most cell phone or laptop batteries are not intrinsically safe! Lithium cells are almost completely recyclable. And - in contrast to lead batteries - they do not contain any hazardous material.
