Page 3: Important Notices
September 2019 1. Important notices It is important to read this manual carefully before using the FES battery pack! It contains important information about FES propulsion system, having a vital importance to the flight safety. If you need more information, please contact the manufacturer of your glider or FES manufacturer LZ design. -
Page 4: 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. -

FES BATTERY PACK GEN2 14S, Version 1.23 September 2019 2.4 Internal BMS FES GEN2 battery pack is equipped with BMS (Battery Management System) electronic circuit. How BMS works? BMS electronic measure and control voltage level of each cell in the battery pack. -
Page 8: Battery Pack Chargers
September 2019 3. Battery pack chargers For charging of FES battery packs, only special FES chargers as described below are approved. If your country is using 110V~ grid, then you should use suitable voltage step up transformer for chargers which required input voltage 230V~ 50/60 Hz. - Page 9 FES BATTERY PACK GEN2 14S, Version 1.23 September 2019 3. FES KOP2300 - optional charger - 2300W; 5,6 kg - maximum charging current 45A. - required input voltage is 80V - 265V~ 47/63 Hz (suitable for US customers as it works on 110V~) 4.

Page 10: Standard Charger To Battery Pack Connection And Charging
FES BATTERY PACK GEN2 14S, Version 1.23 September 2019 Note: Before using the charger, check if the fuse on the grid is suitable. For 1200W charger it should be minimum 10A fuse. For 2300W charger it should be minimum 16A fuse. - Page 11 FES BATTERY PACK GEN2 14S, Version 1.23 September 2019 3. Plug in charger to outlet (220V AC, 50-60hz). 4. Turn on BMS switch on top of the Battery pack cover. Immediately after BMS is switched ON, the BMS starts test procedure - with check of all 14 cells, one by one.
- Page 12 FES BATTERY PACK GEN2 14S, Version 1.23 September 2019 8. When first cell reaches 4.160V, charging current is reduced. If there is a big difference between cells (more than 50mV) then it can take quite long until they all reach 4,16V, as charging current is only 1A.

4. Before flight Valid for FES Self-launchers: For self-launching FES battery packs must be always recharged, so that maximum power for good climb rate is available. This is especially important for: - cold batteries, when voltage drop under high power load is bigger... -
Page 15: Installing The Batteries
FES BATTERY PACK GEN2 14S, Version 1.23 September 2019 4.1 Installing the batteries Warning: Make sure that both battery packs are fully charged before installation into sailplane. Both battery packs must have approximately the same voltage level of each cell (close to 4.16 V per cell). There should be less than 1V difference, between total voltage levels of each battery pack! 1. -

Page 18: After Landing
Caution: For transport and storage of the batteries always a transport box or something similar must be used which protects the batteries from mechanical damage. Make sure you put battery packs on a dry and safe place. Read FES Battery pack manual section 7 and 8 for further instructions. -
Page 19: Maintenance
With proper and carefull use of FES battery packs, there is practically no maintenance required. FES battery packs are built from the most suitable cells available, so that they can provide high power and good endurance and will serve you for many years and charging cycles. -
Page 20: Bms Firmware Upgrade
From time to time there might be available new improved version of BMS firmware. It is easy to perform upgrade, by using provided BMS-Charger-PC cable, and BMS Control software which is available to download from FES dedicated website. If there is any strange behaviour of BMS, upgrade usually resolves the problem. -
Page 21: Transport
September 2019 7. Transport 7.1 Car transport During transportation in the car, FES battery packs must be protected against mechanical damage and moisture. We strongly recommend using: - FES Plastic box (for basic protection), - pair of FES Stainless steel boxes (for advanced protection). - Page 22 September 2019 For advanced protection during transportation, storage or charging we developed pair of FES Stainless steel boxes (optionaly available).

Page 23: In Glider Trailer
Warning: It is not allowed to transport battery packs in the front area of glider trailer. For transportation in glider trailer, FES battery packs must be placed in the battery compartment of the glider, and they must be properly fixed as during flight. -
Page 24: Storage
When you stop flying for longer time, for instance during winter time, it is mandatory to discharge FES battery packs to 50% of charge. This is to middle voltage, 3,7V per cell (this is about 52V per pack, or 104V indicated on FCU instrument, when motor is stopped). - Page 25 FES BATTERY PACK GEN2 14S, Version 1.23 September 2019 Note: Warning sticker as above, with some basic information regarding storage, is located on rear vertical wall of each FES GEN2 battery pack!
