2. Safety Precautions
Reminding
1) It is important and necessary to read the user manual carefully (in the
accessories) before installing or using battery. Failure to do so or to follow
any of the instructions or warnings in this document can result in
electrical shock, serious injury, or death, or can damage battery,
potentially rendering it inoperable
2) 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 90%
3) Battery needs to be recharged within 12 hours, after fully discharged
4) Do not install the product in outdoor environment, or an environment out
of the operation temperature or humidity range listed in manual.
5) Do not expose cable outside

3
6) Do not connect power terminal reversely.
7) All the battery terminals must be disconnected for maintenance
8) Please contact the supplier within 24 hours if there is something
abnormal.
9) Do not use cleaning solvents to clean battery
10) Do not expose battery to flammable or harsh chemicals or vapors
11) Do not paint any part of battery, include any internal or external
components
12) Do not connect battery with PV solar wiring directly
13) The warranty claims are excluded for direct or indirect damage due to
items above.
14) Any foreign object is prohibited to insert into any part of battery
Warning
2.1 Before Connecting
1) After unpacking, please check product and packing list first, if product is
damaged or lack of parts, please contact with the local retailer
2) Before installation, be sure to cut off the grid power and make sure the
battery is in the turned-off mode
3) Wiring must be correct, do not mistake the positive and negative cables,
and ensure no short circuit with the external device
4) It is prohibited to connect the battery and AC power directly
5) The battery supports up to 4 groups of batteries in series. The maximum
charge/discharge voltage should not exceed 57V to avoid the backward
voltage generated by the BMS when the input/output is cut off exceeds the
withstand voltage value of BMS.
6) Please ensure the electrical parameters of battery system are compatible
to related equipment.
7) Keep the battery away from water and fire.

5. Installation and operation
5.1 General guidance
All batteries must be connected in parallel before series connection. Please make
sure the modules are having less than 0.1Vdc voltage difference between each
other, or ideally fully charge the modules in parallel, before connecting them in
serial to avoid capacity imbalance.
The activation voltage shall keep within the charging voltage range, lower
voltage values may cause battery cannot activate.
Imbalance between modules may occur after a period of using in serial
connection, suggest to do a fully charge of the system during 10 - 40℃once per
month.
Up to 4 batteries can be connected in series. If the charging and discharging
equipment has a large inductance, there is a possibility of damaging mosfet, add
a pre-charge resistance to avoid this.
If the battery is entering into sleep mode after running out of power, please
charge it immediately, or at least disconnect the load to avoid over-discharging
the battery due to Long-term shelving.
When multiple batteries are connected in parallel, ensure that the voltage
difference does not exceed 0.5Vdc, to avoid battery charging each other with
high current leads to overcurrent protection between batteries.
When connecting multiple units in parallel, try to ensure that the positive and
negative terminals of each battery to the bus bar are of equal length and have the
same internal resistance.
Please keep at least 2S interval for switching on/off key frequency. Otherwise, it
may cause the battery cannot be turned on.
Please make the wire harness according to the specified wire sequence and
make sure the PIN sequence of the communication harness is the same as the
specified one. Otherwise, the battery may not work properly or be damaged.
When using the Bluetooth function, please do not let the battery covered by
metal shielding, ensure that there is no metal around the battery to shield it,

15
otherwise it will affect the Bluetooth signal strength.
When multiple batteries are connected in series or parallel, it is possible to work
without connecting the communication cable between the batteries to an upper
controller but it is required to connect the internal communication cable in order
to ensure the consistency of SOC and better performance of the batteries.
The LINK1 port of the previous unit in the cascade line needs to be connected to
the LINK0 port of the next unit, please do not connect it wrongly to avoid
damaging the battery BMS.
