Page 3: Important Notices
September 2017 1. Important notices It is important to read this manual carefully before using the FES battery pack! It contains important information about your FES system, having a vital importance to the flight safety. If you need more information please contact the FES manufacturer LZ design. -
Page 4: General Info
September 2017 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. -

What is a BMS? During charging and discharging LiPo battery cells differ in voltage levels, due to slightly different capacity of cells. - Page 7 FES BATTERY PACK GEN2 Version 1.18 September 2017 BMS DATA AND INITIAL SETTINGS Parameter Value Unit Single cell end of charge voltage* 4.16 Single cell charging hysteresis* Single cell balance start voltage* Maximum charging current 9,18,35 Single cell balance 100 %* 4.16...

Page 8: Battery Pack Chargers
Three types of chargers are available for charging FES GEN2 battery packs: 1. KOP602 BMS version (600 W, 2.2kg), maximum charging current 9A. This is standard small FES charger. We provide two such chargers so that both FES GEN2 battery packs can be charged at the same time. - Page 9 BMS which is inside of the battery pack. We program each charger with suitable settings for FES GEN2 14S. Those chargers stores data about charging times and Ah charged. This data may be accessed for further analysis by manufacturer.

Page 10: Charger To Battery Pack Connection And Charging
FES BATTERY PACK GEN2 Version 1.18 September 2017 3.2 Charger to Battery pack connection and charging Place Charger on a safe, secure position. Keep away from dust, direct sunlight, fire, smoke, childrens and any unatendent person! Before charging, physical condition inspection of the battery packs should be done. - Page 11 FES BATTERY PACK GEN2 Version 1.18 September 2017 6. In normal mode green »BMS Power« LED of BMS is starting flashing. This means that the BMS is turned ON, but not necessary balancing. Normally balancing starts when one cell reaches pre-set value, usually 4,1V (could be changed by BMS Control Software).
- Page 12 FES BATTERY PACK GEN2 Version 1.18 September 2017 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.

BMS Control software on PC. In case that some problems are discovered during charging, log file can be created and later you can send it by email to FES manufacturer. It can help us to discover the problem and find a suitable solution. -
Page 14: Before Flight
FES BATTERY PACK GEN2 Version 1.18 September 2017 4. Before flight Before each flight battery packs should be recharged, especially if engine was used during previous flight, so that maximum energy is available if needed. This is very important in cold conditions, where voltage drop under high power load could be significant. -
Page 15: Ground Test Before Each Flight
In case that you would like to test system at max power, somebody needs to hold a fuselage tube down, and hold a glider. 11. Check if propeller braking and automatic positioning is working properly. Standard type of “Connecting cable”, as used on most FES systems.

At the same time, also both BMS switch on top of battery packs, must be switched OFF. Only when connecting cable is unplugged, FES system is completely shut down. Otherwise there is still consumption of about 25mA, which could result in discharge of battery packs, below critical level... -
Page 18: Maintenance
With proper and carefull use of FES battery packs, there is practically no maintence required. FES battery packs are built from the most suitable cells available, so that they are able to provide high power and good endurance and will serve you for many years and charging cycles. -
Page 19: 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 resolve the problem. -
Page 20: Transport
Most of the mechanical damages on the housing, which we recently recognized on alerting number of FES battery packs, seems to be result of unsuitable way of transportation in the cars. We decided that it is mandatory to use FES transportation box. -
Page 21: In Glider Trailer
Australia…), with or without its trailer, we suggest placing FES battery packs into battery compartment of the glider, as there are properly fixed as during flight. Another possibility is to place battery packs into FES stainless steel storage boxes, and fix them to the corner of the container. -
Page 22: 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 23 FES BATTERY PACK GEN2 Version 1.18 September 2017 Warning sticker as above, with some basic information regarding storage, is located on front vertical wall of each FES battery pack!
