2. General info
This is standard FES battery pack which is built from 14 Lipo cells which are all wired
in serial. For FES application, always a pair of such battery packs is required. One pack is
marked as A and second pack as B!
We are using high power SLPB (Superior Lithium Polymer Battery) type of cells,
produced by global leader of Lithium polymer battery industry - Kokam Co.
Each Battery pack is equipped with internal BMS (Battery Management System)
circuit board which is fixed above the cells, and is equipped with 16 LEDs to monitor its
operation.
For + and - terminals 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 10,3mm
contact for + pole.
