I''d err towards caution - everyone knows deep down that parallel batteries are not guaranteed to share charging and load currents evenly so, I''d use parallel arrangements of series batteries each protected by it''s own BMS. So if you have a 3s battery then that has its own BMS. If you have another 3s battery then that should have its own BMS: -

Do I need a protection board for a LIPO battery pack...

The one thing I will say is that protection boards do not manage lithium charging, they only protect from overcharging. You need a charger or brick that is explicitly made for lithium charging; for 3S it''ll be 12.6V and have a two-colour LED to indicate charging/charged. There''s also some solar charge controllers that include lithium
