5. Installation
▲ WARNING!
Read Safety Section before installing the battery.
▲ CAUTION!
Do not install AES LiFePO4batteries in series. Select the
appropriate AES battery model for the voltage of your system.

6
5.1 Tools
• Insulated tools sized to match nuts, bolts and cables in use
• Voltmeter
• Post cleaner and wire brush
• Personal protective equipment
5.2 Locating and Securing the Battery
Locate the batteries close to the power conversion device in order to minimize the length of the battery cables. Care should
be taken to ensure adequate clearance above the batteries is maintained for access to both battery and power conversion
device connections and disconnects.
AES Battery performance and service life will be optimized when they are operated in an ambient temperature of 15°C to
25°C (59°F to 77°F). Care should be taken to ensure that the battery’s temperature is > 0°C (32°F) during charging.
• Battery can be strapped in place with non-conductive nylon straps
• Battery may have hold down brackets at the base of the battery
5.3 Installation
Lithium batteries are very sensitive to voltage and undersized battery cables will impede battery and system performance.
The thickness (cross section) of cable used should exceed the recommended minimum for the charger installation whenever
possible. Do not use or install a battery temperature sensor.
• Conrm that battery is set to OFF
• If the battery circuit has a disconnect - open the disconnect to isolate battery
• Cable connection points should always be kept clean
• Broken, frayed, brittle, kinked or cut cables should never be used
• Secure the new battery - be careful not to ground the terminals to any metal mounting, xture, or body part
• Connect battery cables - connect the ground cable last to avoid sparking
• Terminals are button-type, M8 female - recommended torque is 9.0 Nm (6.64 ft-lb)
• If the battery circuit has a disconnect - close disconnect to reconnect the battery
• Set the battery to ON
▲ NOTE!
All cable ends must be connected to battery terminals without
any washers between terminal bushings and cable ends.
Terminal burnout is caused by:
• Discharge currents exceeding allowable limits
• Improper cable installation
• Improper cable sizing
• Improper terminal torque
▲ NOTE!
Without exception, product experiencing terminal burn out
will not be warranted.

5.4 Conguration with Power Conversion Devices
AES batteries must be set up to work with the Power Conversion devices in either an Open Loop or Closed Loop
conguration. The charge and discharge settings in a Open Loop conguration are set up through the controller for the
Power Conversion device at the time of installation. In a Closed Loop conguration, charge and discharge settings are
dynamically controlled by the BMS of the AES Battery over a connection with the Power Conversion device network. Closed
Loop communication with a Power Conversion device network requires the use of a LYNK Gateway Communication device
(p/n 950-0015) available from Discover Battery.
For Closed Loop and Open Loop conguration details please refer to the appropriate Application Note for your Power
Conversion device available from the Discoverbattery.com website, or contact your Discover Battery provider for assistance.
6. Operation
▲ NOTE!
Review operating limits.
6.1 On–O / Reset
• To set the battery to ON press and hold switch for 2-3 seconds
• To set the battery to OFF press and hold switch for 2-3 seconds
6.2 Charging
Before operating the charger make sure to read and understand the instructions that come with the charger. Never attempt to
charge a battery without rst reviewing and understanding the instructions for the charger being used.
▲ CAUTION!
Always make sure the chargers charging curve meets the battery’s
charging requirement; never charge a visibly damaged battery; never
charge a frozen battery.
1. Connect the Power Conversion device’s charger leads to the battery.
2. Ensure the charger and battery side connections are tight.
3. Set the charger to ON
4. Set the battery to ON
▲ CAUTION!
NOT ALL CHARGERS ARE CAPABLE OF CHARGING LITHIUM BATTERIES
CONFIRM that your chosen charger is incapable of producing transient
spikes that exceed the published terminal voltage limits for the battery.
Spikes are fast, short duration electrical transients in voltage (voltage spikes), current (current spikes), or transferred energy
(energy spikes) in an electrical circuit. Voltage spikes usually happen when the AC/DC adaptor is plugged in, or charge current is
cut off quickly. Multi voltage chargers are constructed using transformers that may be capable of producing spikes that exceed
the maximum ratings of the Discover AES Battery.You must ensure that the charger being supplied:
• Meets the recommended charge curve
• Incapable of exceeding Discover’s maximum terminal voltages

8
6.3 Charge Curve
1. Charge at constant current to 3.4 V per cell module (Bulk).
2. Maintain constant voltage 3.4 V per cell module (Absorption).
3. Terminate when charge current drops below 2A.
▲ CAUTION!
Do not charge battery higher than 3.4 V per cell module.
▲ NOTE!
Recommended charge current is 0.5C.

6.5 Storage
Systems should be stored out of direct sunlight under the following temperature conditions:
Minimum StorageTemperature -20°C / -4°F
Maximum StorageTemperature 45°C / 113°F
Systems should be put into storage at 80% SOC and checked monthly to ensure SOC does not fall below 20%.
At 20% SOC the battery will self discharge in approximately 2 months.
▲ CAUTION!
Do not store a discharged battery. Recharge battery after
every use. Batteries that have self-discharged to a severely
discharge state are not recoverable.
7. Protection & Faults
• BMS generates faults when maximum operating limits are reached.
• BMS sounds a buzzer when fault limits are triggered.
• BMS monitors the following information for faults and warning:
1. Cell module voltage
2. Battery current
3. Battery temperature
▲ NOTE!
Refer to device technical specication tables at the end of
this manual for Fault Limits.
CORRECTIVE ACTIONS
HighTemperature • Stop discharge or charge
• Leave the battery to cool
LowTemperature • Stop discharge or charge
High Voltage • If charging stop the charge
• Conrm proper charge algorithm is being used
Low Voltage
• Do not discharge the battery - if any discharge current is detected, this will force the
battery into Low Voltage Fault
• Charge the battery in Low Voltage Recovery - if no charge current is detected within 2
minutes the BMS will set the battery to OFF
Over Current • Reduce current
Low SOC • Stop discharge
• Charge the battery
Inaccurate SOC displayed by
Power Conversion system
• Battery voltage based SOC calculations provided by Power Conversion systems do
not work properly with Lithium battery voltage.
• Use a Discover CAN Bus Battery Discharge Indicator (p/n 950-0005, 950-0006,
950-0007) to display accurate SOC.To communicate accurate SOC in a closed loop
Power Conversion system use a Discover LYNK Communications Gateway device
(p/n 950-0015)

8. Service & Maintenance
Batteries should be carefully inspected on a regular basis in order to detect and correct potential problems before they do harm.
This routine should be started when the batteries are rst received.
8.1 Inspection
• Inspect for cracks in the battery casing
• Check battery terminals and connections to make sure they are clean, free of dirt, uids and corrosion
• All battery cables and their connections should be tight, intact, and NOT broken or frayed
• Replace any damaged batteries
• Replace any damaged cables
• Ensure correct torque is used for the terminal bolts
8.2 Firmware Updates
Consult Discover’s website for the latest rmware. If an rmware update is require, ensure this is done by a qualied installer.
9. Troubleshooting
9.1 Battery Will Not Turn On
Symptom Does the battery turn on for a short time then turns itself off?
Description The battery is likely in a low voltage or low SOC.
Action Connect to charger and turn on the battery.
Symptom Was the battery left on or stored for extended periods of time?
Description The battery will turn itself off at 5% SOC. If left sitting at a low SOC, the
battery may have discharged itself completely and cannot be used.
Action Do not use. Replace and recycle.
Symptom Does the battery appear to turn on, but has no voltage at its
terminals?
Description The battery fuse is likely blown.
Action Replace fuse. Contact Discover for support.
10. Recycling and Disposal
Batteries must not be mixed with domestic or industrial waste. Discover Advanced Energy Systems are recyclable and must be
processed through a recognized recycling agency or dealer. Please contact Discover or your servicing dealer for details.
