I grabbed an Everstart H6 AGM from Walmart @ $169 and installed it with my fresh Aliexpress cloth cover. Coded her in with OBD11 and thats about it for today. I might be installing a trailer harness soon, which will be a chore.
Got a link for that battery cover? I asked at the dealer and when even the parts guy laughs at how expensive it is (over $100CAD)....you take a pass on that.
