Special Attention: Due to the built-in protection board of the lithium battery pack is with
over-discharge protection function, it is strongly recommended to stop using the load when
the battery pack is over-discharged. The battery pack cannot be repeatedly activated for
discharge. Therefore, when the battery pack is low power, please charge the battery as
soon as possible when main power or solar energy is available.
1. The batteries can be connected in parallel. Series connection is not allowed.
Use in upright position only.
2. The batteries are not allowed to connected with PWM controller for charging.
1.4 Can be connected in parallel

3.2 Mounting the Unit
Consider the following points before selecting where to install:
• Do not mount the battery on flammable construction materials.
• The ambient temperature should be between 0°C and 45°C to ensure optimal operation.
• The recommended installation position is to be adhered to the wall vertically.
• Be sure to keep other objects and surfaces as shown in the right diagram to guarantee sufficient heat
dissipation and to have enough space for removing wires.

Remark①: 1 in SW1-SW5 indicates ON status, and 0 indicates OFF status.
Remark②: When multiple battery packs communicate, the last battery pack SW5 needs to be in the ON
status, otherwise the communication may have interference.
Remark③: When the battery pack ID is set to 0, it means stand-alone operation, and it is not necessary to
detect whether the parallel condition is satisfied ⑤
Remark④: When the battery pack ID is set to 1-15, it means that the parallel operation is required, and it is
necessary to detect whether the parallel condition is satisfied ⑤
Remark⑤: The parallel condition is that the difference between the battery voltage of the local battery and
all the battery pack voltages is <3V, otherwise wait until the condition is satisfied

Once the batteries are connected well, simply press On/Off button to enable the output of the battery pack.
4. OPERATION
1.Switch on: press On/Off button to switch on the battery, then the battery will do self-inspection before
enable output. The LED will show the SOC.
2.Switch off: press and hold On/Off button for 3 seconds, the battery will shut down directly.
