Page 4 of 26
2. General info
This is standard FES Battery developed especially for FES application. In each battery
pack there are 14 cells, all wired in serial (14S). For standard 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 14+2 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.
