2A batteries are enough for 1-2 days of active work, charging in half an hour, so if you use them only in Shurik and nowhere else, 1.5A and 1.3A batteries will suffice. But improve compactness and lightness. Some pros: I would say this is the perfect tool for the home. Because I bought myself with a power of 70 Nm and this power is redundant for me. It's the perfect combination of power and compactness. I recommend with batteries of at least 2A, but it is better to look with batteries in the kit, because the batteries separately cost much more than they will already be in the kit. If another Dewalt tool is planned, take it with 5A batteries and already at 18V - there will be a more universal set. But it will lose in compactness and lightness. Has cons: There are no kits more powerful than the 2A batteries included, and the batteries are much more expensive separately. 12V - universality disappears. You can’t charge another acc from another Devolt tool at 18V and interchangeability disappears - you put 18V batteries on another Devolt tool and work, you bought Shurik here, you only have Shurik.
