Precautions
Note 1
Please always refer to the latest version of the technical manual published on our website to ensure safe and efficient operation.
Note 2
For parallel connections, fully discharge the batteries before connecting them in parallel, and then recharge them. For series connections, ensure the remaining capacity of each battery is the same.
Note 3
Parallel connections are intended only to extend backup time, not to increase output power.
Note 4
The company assumes no responsibility for any accidents caused by not following this user manual.
