This is the one you want. Don't try to 'save a little more' by getting 'about the same thing' because you need it yesterday. You'll just end up spending as much (and twice the time) as the dealer. Ask me how I know...

Price was a bit high but made in the USA and is the exact reaplcement for BMW i3's 12v battery. It even has a hole for the vent tube.
