A Ryobi ONE+ starter bundle: a 4.0Ah HP battery, a 2.0Ah HP battery, a charger, and a cordless 4-1/2 in. angle grinder. The HP packs use IntelliCell electronics and COOL-CORE heat management to hold output under load, and an LED fuel gauge shows remaining charge. It suits anyone already on the ONE+ system who wants spare runtime plus a grinder, and it beats buying the batteries and tool separately. Owners rate it highly, though the 2.0Ah pack drains fast in high-draw tools.

Owners rate the kit 4.8 out of 5 and mostly praise the battery runtime and the bundled grinder. The main complaint is the small 2.0Ah pack's short runtime in demanding tools.
This RYOBI ONE+ 18V starter kit includes a 2Ah HP battery, a 4Ah HP battery, a charger and a ONE+ 18V 4-1/2 in. angle grinder. The grinder is sold as a tool only, so it comes without a battery of its own. The batteries power any 18V ONE+ tool, and any 18V ONE+ battery works with any 18V ONE+ product.
IntelliCell Electronics manage power and runtime to maintain performance during demanding use. The COOL-CORE heat management system regulates pack temperature to keep the battery cooler and its output consistent. The pack design includes anti-vibration technology for protection against impacts and everyday wear.
A high-visibility LED fuel gauge shows the remaining runtime. When paired with an 18V ONE+ HP tool, the battery works with brushless motors and advanced electronics for more power and longer runtime. The kit is backed by the RYOBI 3-Year Manufacturer's Warranty.
