    4 Application Description 4.1 Parallel Connection Application The battery packs support parallel connection, and synchronously increases the backup time or backup power. Confirm the consistency between the battery packs, check the SOC and voltage and turn off the batteries before connecting them in parallel. Multiple battery packs of parallel connection need to use RS485/CAN to communicate, pay attention to the DIP switch settings.
