1.12.2 / woot-1.15.2-1.1.1.2.jar | Heart won't recieve power

[bdtran2002]

Hi i've been trying to figure this out. The whole farm are in solid connected parts and when I right click on the heart with the hammer everything is okay and it even identifies the power block yet when I look into the heart itself it says that it doesn't have battery as in the energy bar is at 0. This version doesn't have any cables that come with the mod unless the cables are from another mod nor does it have any sort of creative God power cube. I don't really understand what's not working
