Pros & Cons
Pros
- Bundles a 4.0Ah 40V battery (OP4040) with a charger (OP403A) in one genuine Ryobi kit
- 4.0Ah is a mid-to-high capacity pack for the 40V outdoor-power platform
- Currently in stock on Amazon
- Genuine Ryobi OEM parts, not aftermarket
Cons
- Only one battery included — no second pack for hot-swapping on longer yard jobs
- 40V packs are heavier than ONE+ 18V packs, worth weighing if you're carrying it around
- We haven't independently timed a charge or measured runtime; 4.0Ah is Ryobi's stated rating
