5. Electrical Connection
Note!
It is noted to distinguish the positive and negative ends of cables.
Be careful to avoid misuse of lines used for communication between PCS and battery, battery and
battery.
Try to avoid cross-connection.
Before connect the cable with the PCS, the worker must confirm the output switch of the PCS has
been turn off, to prevent the risk of fire or electric shock.
Exercise extreme caution to prevent the terminals from contacting anything except their intended
mounting points.
When tightening the screws, make sure they are at a straight angle from the battery module
terminals to avoid damage to the nuts inside.
The power terminals, such as “+,” “-,” of the module are covered with the protecting cover to
guard against a short circuit.
You must remove the insulation cover prior to connecting and reattach the insulation cover
immediately after connecting.
5.1 Grounding and DC connection
24
Step 1: Wear the protective gloves.
Step 2: Remove the ground screw using a socket wrench, and then install the ground cable and
the screw. Install the another end according to local regulations.
Step 3:
When using the product in parallel,use the 150mm BCables described in the Chapter 3. 1.
Connect the B+ port between battery packs with red cables, connect the B- port with black cables, and
connect the OUT port of the first battery pack to the IN port of the next battery pack with black
communication cable.
When connecting to PCS, use the 1500mm PCables described in the Chapter 3. 1. PCSB+ port is connected
to B+ port of battery pack with red cables, PCSB- port is connected to B- port of battery pack with black
cables, and the PCS port of the battery pack is connected to the BMS communication port of the PCS.
Note!
Make sure all fasteners are secured and all cables are connected firmly.
When monitoring batteries by the computer, carry out the wiring as shown in the following
picture.
25
5.2 Parallel Mode
When batteries need to be used together in parallel, you can select different parallel modes to meet
your demands.
Note!
As shown in the following pictures, connect the communication cables (a standard RJ45 network
cable) between the adjacent batteries.
The PCS port of the first battery must be connected to the inverter's battery communication
interface, otherwise the inverter cannot communicate with the batteries.
The OUT port of the first battery is connected to the IN port of the next battery, and so on,
connecting the communication of multiple batteries together,otherwise multiple batteries will not
be able to communicate correctly.
5.2.1 Mode 1
Caution!
When multiple battery packs are connected in parallel and linked to the inverter via busbars, the
cables between the busbars and the inverter must be matched according to the inverter's maximum
output power. Taking a 12kW inverter as an example, with a battery pack voltage of 51.2V, the
minimum continuous current-carrying capacity required for the cables is 240A. You must select high-
quality cables with a current-carrying capacity ≥240A (recommended specifications: 50mm² or 1/0
AWG and above).
Caution!
Using cables that are too thin can lead to severe overheating, fire hazards, and equipment damage.

Close the air switch first, and then turn on the power button to prevent battery short-circuit
protection failure caused by the precharge function.
Start the Battery:
After installation, wiring, and configuration are completed, you must check all the
connection. When the connections are correctly, and then press power button to activate
the battery. The green working light on of the battery flashes, indicating that the battery
system is normal.
6.2 Monitoring your unit
Monitoring parallel units：
The first method is to use connect the upper computer to the communication port of any battery
pack and view the status of all packs.
The second method is to connect the PCS communication port of the first battery pack with a
communication cable,and the other end is connected to the 485 communication port of the
inverter.Then,
connect the positive pole to the positive pole and the negative pole to the negative pole. Switch the
Inverter to lithium mode and check the condition of several packs through the inverter display
screen.

7 Inspection, Cleaning and Maintenance
7.1 General Information
The battery product is not fully charged. It is recommended that the installation be completed
within 3 months after arrival;
During the maintenance process, do not re-install the battery in the battery product. Otherwise,
the performance of the battery will be reduced;
It is forbidden to dismantle any battery in the battery product, and it is forbidden to dis- sect the
battery;
After the battery product is over-discharged, it is recommended to charge the battery within 48
hours. The battery product can also be charged in parallel. After the battery product is connected in
parallel, the charger only needs to connect the output port of any product battery.
Never attempt to open or dismantle the battery! The inside of the battery does not contain
serviceable parts.
Disconnect the Li-Ion battery from all loads and charging devices before performing cleaning and
maintenance activities.
Place the enclosed protective caps over the terminals before cleaning and maintenance activities
to avoid the risk of contacting the terminals.
All the battery terminals must be disconnected for maintenance.
Please contact the supplier within 24 hours if there is something abnormal.
Do not use cleaning solvents to clean battery.
7.2 Inspection
Inspect for loose and/or damaged wiring and contacts, cracks, deformations, leakage, or damage
of any other kind. If damage to the battery is found, it must be replaced. Do not attempt to charge or
use a damaged battery. Do not touch the liquid from a ruptured battery.
Regularly check the battery’s state of charge. Lithium Iron Phosphate batteries will slowly self-
discharge when not in use or whilst in storage.
Consider replacing the battery with a new one if you note either of the following conditions:
-The battery run time drops below 70% of the original run time.
-The battery charge time increases significantly.
7.3 Cleaning
If necessary, clean the Li-Ion battery with a soft, dry cloth. Never use liquids, solvents, or abrasives to
clean the Li-Ion battery.
7.4 Maintenance
The Li-Ion battery is maintenance-free. Charge the battery to approximately > 80% of its capacity at
least once every year to preserve the battery capacity.
32
8 Storage
The battery product should be stored in a dry, cool, and cool environment;
If the battery is stored for long time, it is required to charge them every six months, and the SOC
should be no less than 50%.
Generally, the maximum storage period at room temperature is 6 months. When the battery is
stored over 6 months, it is recommended to check the battery voltage. If the volt- age is higher
than 51.2V, it can continue to store the battery. In addition, it is needed to check the voltage at
least once a month until the voltage is lower than 51.2V. When the voltage of the battery is lower
than 51.2V, it must to be charged according to the charging strategy.
The charging strategy is as follows: discharge the battery to the cutoff voltage with 0.2C(20A)
current, and then charge with 0.2C(20A) current for about 3 hours. Keep the SOC of the battery at
40%～60% when stored;
When the battery product is stored, the source of ignition or high temperature should be avoided
and it should be kept away from explosive and flammable areas.
