Did not fit the yellow top Optima battery 1/4″ too short to lock down the tie down strap…
Good Morning Kevin,
We are sorry to hear that you had difficulties with the installation. The Twist Dynamics battery conversion kit was specifically designed around the Optima Yellow Top battery (Model D34/78), so if you purchased a different Optima it may not line up. If you did purchase the correct battery and are still having difficulty with the installation, please give us a call and we would be happy to try and walk you through the process. Thank you so much.

Nice Quality. I have a 2016 SL and it fit great. Think I had it installed in 10 min. Strapped in my Optima Yellow top and I’m back up and running!
