Rechargeable Battery Pack Design

Thought for 16 sec

The “Execute” button appears right below my last message in this chat pane (not in the schematic editor itself). Just scroll down in the chat window—you should see a button labeled Execute directly under the text where I offered to add the parts. Click that to apply the changes.
