Yep, best to use a (thin) conductor to tie all 3 center posts together
and the cell level BMS.
Although I have seen people chance it, depend on the low voltage
cut-off of the load and the max voltage setting on the charger and
hope the modules stay in balance...

Is your E10 being used in winter (snowblowing, ploughing)?
If so, see to it that you can park your E10 in a location that is not
below freezing.
Or you can heat your batteries.
Charging your (Leaf) Lithium batteries when they are cold (below
freezing) will cause them to fail quickly from something
