I've been watching a lot of these lately and it's a shame the channel doesn't get much attention, because it has potential. I have found faults in a few of them and some of them give a few omissions that could be very misleading, but overall they provide accurate accounts of what happened. They include a wealth of political and societal background information, along with events leading up to the battles before showing how they played out on the field. From what I can tell they do not cover any East Asian, Southeast Asian, or Central Asian battles at all and only one South Asian battle I know of involving the 16th-century Mughals. They do have some battles that occurred in West Asia and North Africa, most of them in ancient times. Most of the videos focus on Europe, though, from Antiquity all the way until the Modern age.
Perhaps unsurprisingly they use Rome II Total War type maps and graphics, even some of the same music.
Here are some examples that you might enjoy; feel free to critique them too:
