After installing, I can see this battery can be placed into MK3 armour. It also shows it has been researched together with MK2 battery pack. However, I do not see the battery in crafting inventory, which means the battery cannot be crafted. Im using few other mods, so there might be a collision with something else. Im not gonna switch all of them one by one, to check which one is it, I just wanted to point out that something like this might happen.
