5 Packaging, transportation, storage
requirements
5.1 Transportation
Always check all applicable local, national, and international
regulations before transporting an LFP battery.
During the transportation, protected the battery from severe
vibration, shock or squeezing during transportation, as well as to prevent
sun and rain.
During the loading and unloading process, the battery should be
handled lightly and protected against falling, rolling and heavy pressure.
5.2 Storage
Follow the storage instructions in this manual to optimize the
lifespan of the LFP battery during storage. If these instructions are not

DLG E-BOX-48100R LFP Battery User Manual
8
followed and the LFP battery has no charge remaining when it is checked,
consider it to be damaged. Do not attempt to recharge or use it. Replace
it with a new LFP battery.
See previous storage temperature conditions.
The self-discharge of the LFP battery is 1-2% per month. Keep the
battery SOC to 40%-60% during storage.
1. Disconnect the LFP battery from all loads and, if present, the
charging device.
2. Store the battery in a cool and dry place without direct sunshine.
3. Keep the battery away from corrosive substances, inflammable and
explosive material as well as hazardous gases.
4. For long-term storage (＞6months), charge the LFP battery to more
than 80% of its rated capacity before storage. The battery needs to be
recharged every 6months to more than 80%of the rated capacity.
6 Installation and configuration

Always observe local safety regulations and the safety requirements
listed below during installation process.
Before installing or removing the device, make sure that the power
system is not powered and that the battery device is turned off.
Distribution cabling should be reasonable and with protective measures
to avoid being touched during operation.
6.1.2 Checking the operating environment
The operating environment should meet the requirements
described in Chapter 4, “Operating Environment”. Otherwise, it needs to
be adjusted and re-examined.

6.1.4 Technical preparation
Electrical interface settings:
If the battery is connected to the user device directly, please check:
●Whether the DC charging interface of the energy storage inverter
meets the charging voltage and current requirements in Table 2-1
Battery Pack Specifications.
●Whether the power of the electrical equipment matches the
parameters listed in “Table 2-1 Battery Pack Specifications”;
Security check:
Fire-fighting equipment such as portable dry powder fire
extinguishers should be available near the equipment. Do not place
dangerous materials such as flammable or explosive ones near the
battery.
6.2 Unpacking
●When the battery arrives at the installation site, it must be loaded and
unloaded properly and prevented from the direct sunshine and rain.
Before installation, check if there is any component missing according

DLG E-BOX-48100R LFP Battery User Manual
11
to packing list attached in the packing box and check whether the box
appearance is intact;
●Carefully handling during the unpacking. Protect the insulated coating
on the case surface;
●Check the LFP battery for damage after unpacking. If there is any
damage, contact DLG or your reseller.
6.3 The preparatory work
1. Make sure the POWER buttons of all batteries are OFF
2. Ensure the charging voltage of power supply equipment is DC57.5±
0.1V;
3. All power supply should be off
6.4 Installation
6.4.1 Install the battery
The E-BOX-48100R can be installed either vertically or horizontally.
In this chapter, it’s mainly instructions for horizontal installation such as:

DLG E-BOX-48100R LFP Battery User Manual
12
installation in a 19-inch cabinet. Vertical installation is similar. All
equipment must be steady during installation.
6.4.2 Connect Ground cable
Unscrew the screw at the grounding hole on the front panel of the
battery, wrap the ground cable around the screw, and tighten with a
screwdriver. Connect the other end of the ground cable to a reliable
ground point.
Note: The grounding resistance should be less than 1Ω.
6.4.3 Connecting the power cable
Before connecting the power cable, connect and disconnect the
cable to identify the positive and negative terminal, then make a mark
respectively. After the cable is connected, measure whether there is a
short line or reverse connection.
Connecting the power cables:
(1) Power cable connection instructions of Single-Rack:
●Single battery: Connect the positive pole of the battery to the positive
terminal of the DC port of the energy storage inverter (or the junction
box) with a red cable, and connect the negative pole of the battery to
the negative terminal of the DC port of the energy storage inverter (or

DLG E-BOX-48100R LFP Battery User Manual
13
the junction box) with a black cable.
●Multiple batteries: the connection between batteries, as well as the
connection between the battery and ESS inverter is in parallel. First,
connect the two positive terminals of adjacent batteries with the red
cable; connect the two negative terminals of adjacent batteries with
the black cable; connect the positive pole of the battery with the
positive terminal of the DC port of the energy storage inverter (or the
junction box) with a red cable; connect the negative pole of the battery
with the negative terminal of the DC port of the energy storage
inverter (or the junction box) with a black cable.
(2) Power cable connection instructions of Multi-Rack:
Collect the positive and negative power cables respectively by the
bus bar or junction box, then connect two racks in parallel.
The length, thickness, material, and resistance of the cables
connected in parallel should be the same.
Note: When the cable is inserted into the positive and negative
terminals of the battery and “Click”, the cable is firmly connected. Before
pulling out the cable, press the small button next to the terminal. When
multiple batteries are connected in parallel, in order to reduce the
influence of the circular current, the overall positive and negative output

14
cables can be connected from different batteries.
Figure 6-1 Schematic diagram of battery connection
6.4.4 Connecting communication cables
Single battery: Choose which port to be inserted according to the
communication protocol (RS485/CAN/RS232) between the battery
and ESS inverter, then insert the communication cables to the port;
Multiple batteries: The host and the slave communicate in
cascade mode: one is the host and the rest are the slaves. Please
