Step 1: What you start out with:
Step 2: Removing the batteries from the battery Box
First; remove the straps that connect eh batteries to the hotpoints on the side of the battery box.
When these are loose we found that removing the two batteries closest to the hotpoints released the rest of the batteries to be slid out more easily.
Step 3: Removing old batteries part deux.
Step 4: Finally they're out!
Step 5: Test Fit New Batteries
Step 6: Cut Packing Foam to fit around the battery cladding
Test fit the foam...
It looks great! no place for that batt to move!
