Customized Battery packs
Our battery packs are based mainly on the 18650 format cylindrical cells due to their excellent energy density.
Our favourite cell is Panasonic NCR18650PF , sourced from Japan. While they don`t have the highest outright discharge rate , overall they are they best cell , i.e. good cycle life, safe chemistry , consistent quality , etc.
We can of course construct battery pack from very high discharge cells like Sony 18650VTC5 or A123 26650 2.3Ah.
Our CNC mill provides us with with the ability to make battery assembly of virtually any shape.
Pouch cells and large cylindrical formats are also supported, there is more information in the “CNC milled battery assemblies”. Waterproof acrylic boxes can be supplied at additional cost.
All our packs come with a powerful charger included in the price, because we believe fast charging times are important for an electric vehicle to be practical.
Below are listed only some examples , packs of any configuration can be made on request.
