Battery packs and its chargers
Standard FES battery pack contains 14 cells which are all wired in serial. For FES
application you need two of them. They are marked with serial number and a letter first as
A pack and second as B pack!
We are using one of the best high power SLPB (Superiol Lithium Polymer Battery)
cells available on the market produced by world renowned manufacturer Kokam. You can
find detailed technical data about these cells in
Technical Specifications.
•
Older “Battery packs GEN1” has external BMS (Battery Management System)
•
Newer “Battery pack GEN2” are equipped with internal BMS (Battery Management
System) which is fixed above the cells, and is equipped with 16 LEDs to monitor its
operation.
For + and - terminals (GEN2 packs only) we chose to use Amphenol Radsok
hyperbolic high power contact technology. High current female contacts are hidden inside
of the pack.
To avoid possible wrong connections there is 8mm contact for – pole and 10mm
contact for +pole.
