FES GEN3 14S 53Ah Battery Packs are developed especially for FES application, however for bureocratic reasons suitable only for non-EASA gliders.
There are 14 cells, all wired in serial (14S) in each battery pack. Average capacity of each cell is 53Ah. A pair of battery packs is required in a FES system. First pack is marked as A and second pack as B.
We are using high power cells, produced by global leader of Lithium battery industry – Kokam Co.
Each Battery pack is equipped with BMS (Battery Management System) circuit board, which monitors its operation. New GEN3 feature additional e-ink display – which indicates state of charge, and G-load sensor, which monitors potential mechanical abuse.
