First, brushless motors have become more prevalent. The advantage has become greater over the past couple of years on two fronts.
The initial advantage of the Makita 18V X2 LXT system is in its inherent design that gives users the ability to purchase more powerful 36V tools while using the batteries they already own. Makita plugged along, bringing out new 18V X2 LXT tools when it made sense but still focusing on expanding their 18V LXT system, which is the workhorse of their cordless lineup. Still, others remained committed to their 18V platforms, citing the benefit of keeping their users on one battery system. After all, some companies developed their 36V platforms to great success with more powerful cordless tools. When Makita first launched the X2 system, Pros and enthusiasts alike questioned if an onboard series connection is the best way to move to a more powerful tool. That happens on the tool itself with no adapters required.
Rather than creating a 36V platform, Makita found a way to create a series connection between two 18V batteries to get there. By connecting two batteries with a series connection, you add the voltages together. Makita 18V X2 LXT cordless tools take advantage of a more simplistic design.
