I have a multitool that includes a drill and a C4 hammering drill (3 joules). Right now, I own one 4Ah smart battery and one 2Ah battery. I'm looking to purchase two more batteries. Should I buy two 4Ah smart batteries, or should I go for one 4Ah and one 8Ah? I currently have a 2.4A charger (the one that came with the 2Ah battery) and I'm considering getting a 4.5A charger and possibly a double charger as well. I'm also planning to get a 226 Nm impact driver and possibly a 150Nm drill if it has a hammering function. So far, I used the 2Ah battery during half a day of sanding and screwing. While I don't necessarily need the 8Ah battery, I'm curious if it offers significantly more power than the 4Ah for the hammering drill, and whether the added weight is worth the extra power. Any thoughts?

If budget isn't a big deal for you, I'd suggest getting one 4Ah and one 8Ah battery. The 8Ah battery gives you a lot more power and longer runtime, especially for the hammer drill. It's not super expensive either! The 4Ah smart battery is great for most drills and impacts since it's lightweight and manageable.
