Safety

1.1 General recommendation
Each person given the task of operating or maintaining the battery must have read and understood the instructions. Only qualified
personnel should install the batteries. Knowledge of the contents of the installation and user manual is a fundamental requirement
to protect people from danger, to avoid errors and to operate the system safely and fault-free.
1.2 Installation / Operation
● For the first use, before connecting the battery packs to your equipment fully charge the battery (see section 2), this will put
battery in good SOC and will calibrate SOC calculation from BMS
● The operating conditions given in the product documentation must be observed
● The battery contains a BMS with integrated protection and with the capability to disconnect all battery power resulting in 0 V and 0 A
● A battery which gets disconnected by BMS during use can lead to immediate loss of function for connected equipment.
Do not install or use in systems where sudden loss of battery power may lead to dangerous situations or result in malfunction or
damage of connected equipment
● The battery is intended for equipment use only. Do not use for starting power (engine crank) or other similar applications
● If the battery is damaged, deformed, abnormally hot or emits an odor, please cut off the power immediately and stop using it and
contact your local dealer

1.3 Battery Maintenance

● Exide Li-ion charger is recommended to be used. If using any other charger it must respect the charging requirements of the
battery (see section 2)
● Depending on battery type, if the battery voltage is lower than 10 V / 20 V / 30 V the BMS will disconnect (over discharge protection)
and enter sleep mode to protect the battery from further discharge. Apply charging voltage to wake up BMS and recharge battery
immediately
● The user should verify the condition of all external cables and connections prior to each operation
● Before carrying out any inspection of cables the battery must be disconnected from the application and the charger

1.4 Storage conditions

● Disconnect all loads from the battery before storage
● In case of long term storage (>6 months), battery must be kept dry and frost free. Storage temperature 15 – 35 °C, recommended
storage humidity 5 ~ 75%
● In case of long term storage (>6 months), maintain battery state of charge (SOC) close to 50% by maintenance charge every
6 months. For seasonal storage (up to 6 months) charge the battery to above 50% SOC before disconnecting
● Suggested storage temperatures up to 1 month -20°C ~ 50℃, up to 3 months -10°C ~ 45°C
● If battery need to be stored for prolonged time (e.g. for winter), recharge them upfront and check battery open circuit voltage,
OCV (voltage at total rest, ideally with nothing connected to battery terminals) regularly every 3 months
● In case OCV >12.6 V battery state of charge is above 10% and can be considered OK. Below 12.6 V battery should be charged.
At 10.5V the low voltage protection is triggered
● To recharge, use Exide approved Li-ion charger or other Li-ion battery charger (lithium iron phosphate, LFP) fulfilling charger
specifications as described in this manual. To recharge a battery in low voltage protection mode, the charger must be able to start
charging from 0 V. Make sure the charger is capable of activating also when battery voltage is 0 V (e.g. use power supply function,
automatic starting function, or similar setting). Note that some chargers do not have this capability and will not be able to «wake up»
a Li-ion battery from low voltage protection, refer to charger manual for details and use a different charger if required
