I felt that the base Power Armor health was too low, particularly on lower iterations of the power armor such as 45A. What I have done with this mod is increase the base HP of all power armor pieces in the game. This mod does not affect any power armor sets added by other mods, though I suppose it's possible if a mod replaces a vanilla power armor set with a different set and that set has different stats then there may be some conflict. I have tested this in game and it seems to be working fine and should not interfere with any other mods that affect power armor, such as skins or protection enhancements, so long as they do not also alter the base HP of power armor pieces. Specifically, what this mod does is increase the base HP of all power armor pieces by the same ratios. All chests are increased by 50% and all limbs and helmets are increased by 200%, thereby trippling their health. The result is that all limbs and helmets have half as much as health as their corosponding chest pieces. As example, T-45A goes from 200 HP on the chest and 50 HP on the limbs to 300 HP on the chest and 150 HP on the limbs. This mod affects all Power Armors, including the Power Armors added by the Automotron DLC and the Nuka World DLC and so Automotron and Nuka World are required for this mod to function.
Armor stats are universal regardless of special varient. i.e., the Nuka T51 has the same health as regular T51. The following are base health for the lowest varients. Upgrades increase from base health, meaning T45 C will still have more health than T45 A.

Update 1.1
In my own playthrough I discovered Tesla Armor of the Automotron DLC and so I went in and modified it in the same way as I did the vanilla power armors so now the Tesla Armor will be on par with vanilla T60.
Update 1.2
Now affects power armors added in Nuka World.
