The DCG405P1 comes with one battery (5Ah), the DCG405P2 comes with two batteries (5Ah), and the DCG405P3 comes with three batteries (5Ah).

Cordless angle grinder with 800 W of useful power. The tool is equipped with a highly efficient brushless motor, which is more reliable and uses battery power more economically than traditional motors. Various types of equipment with a diameter of 125 mm can be installed on the spindle of the DeWALT DCG405P3 angle grinder: abrasive and cutting discs, flap grinding wheels, wire brushes, etc.

Thanks to the engine brake, the equipment quickly stops rotation after releasing the button. The angle grinder boasts an electronic system for protecting the engine from overloads. The safety (disengagement) clutch protects the tool and the user from kickback if the equipment gets jammed in the material being processed. An additional handle is screwed into the gearbox housing on the left or right. The openings in the tool housing are covered with mesh filters to protect the insides from dust. In this package, the grinder comes with a plastic case, a charger and three rechargeable batteries, each of which has a large capacity (5 Ah).

Model overview based on user reviews  
The DeWALT DCG405N is a highly regarded angle grinder, praised for its power, comfortable grip, and compactness. Users appreciate its quality materials and find it to be a great helper for working with metal, concrete, and tiles. It is particularly beneficial for those who already own DeWALT cordless equipment, as it fits seamlessly into the existing setup. While it lacks speed control, which might be necessary for delicate work, it excels in tasks requiring a reliable and powerful tool. The grinder is simple, convenient, and can be operated one-handed, saving time and effort. However, it does not include a basic strap or attachment point for safety, which could be a concern for preventing falls. Overall, it is an excellent auxiliary tool for small jobs, especially where using an extension cord is inconvenient.
Pros

Cons

great model, love it
3 August 2020 
I finally bought a DeWALT DCG405N 6B90D, this device. I bought it for a variety of jobs, to sharpen it little by little, to cut off a couple of fittings, to quickly sand small areas, to correct tiles, to easily saw off a 50mm steel angle with a 2A battery. A gufchem for small jobs, for which unwinding the extension cord turns into great difficulties. Using it fully as an ordinary grinder is stupid, the tool is exclusively an auxiliary tool for the network tool.
The tool is simple, convenient and one-handed. Saves a lot of time and effort.
There is no basic strap or hole where you can attach the device to the foxes. Let's say protecting a fall from a height or crooked hands.
