Looks like you have F2 terminals on that battery and F1 connectors on the wiring. I know there is a such thing as an F1 to F2 adapter, probably the opposite exists too. If you can take the battery back and get one with the correct terminals that would be best. You can change the adapters on the wiring, but that will lead to warranty problems if you're worried about that. I had the opposite problem with the first battery I bought off of Amazon for my Streamlight HID Litebox. Check my recent thread on that in this subforum.
