Note
• To avoid triggering battery protection due to the large voltage difference, it is recommended
to connect the batteries in parallel, float charge them for 24 hours after a full charge, and
then use them in series and parallel connection.
• When connecting the batteries in series and parallel, please connect them in series first and
then in parallel.
• Up to 16 identical batteries are supported in series and parallel connection (Max 4S4P).
