300ah smart Lithium battery single cell voltage drop

Hi,


One of my 300ah batteries (600ah system) drops cell voltage under load (1500watt load via 3000 multiplus)

Yes temperature is slightly high, but it's the same at lower Temps.

The voltage comes back normal once the load subsides.

Is this a bad sign? Anything I should do to rebalance these?
