Hey there, edspyhill01.
After reviewing your post, it appears you're not seeing the Battery widget in the Notification Center of your iPad Pro. I'll be glad to help you with this.
iPad User Guide - Notifications -- To get to the Notification Center on your iPad Pro, swipe left from the Home screen. Then, scroll down to the bottom and tap "Edit". You will find the Battery widget located on the "Add Widgets" screen. Scroll down until you locate it and then tap the plus sign to add it to the Notification Center. Also, from the "Add Widgets" screen, you can remove any widgets you don't find useful by select the minus sign on the left side. You can adjust which widget is displayed first by pressing and holding the three lines to the left of the one you want to relocate and drag it up or down.
Thanks for using Apple Support Communities and have a great day!
