No, and don’t listen to anyone who does recommend one. If you have yet to purchase your batteries then make sure that you buy ones with integral heating. If heating is required, those batteries use the charger supply, and not the batteries, to provide the heat.

Is it better to have 2 smaller batteries or 1 big?

Depends on the BMS and your anticipated draw. Two batteries in parallel will often (usually) have a higher discharge limit than a single large battery.
However, that means that you have to view (via the bluetooth app) the batteries’ status/health separately; this is not necessary with a single battery.
