Stock battery: 60lb with stock bolt-down bracket

Weight savings: 51lb

Battery cost: $1100 (mine was nib never installed so I got it for less secondhand)
Bracket cost: $25 because I used ti fasteners I had lying around

Cost/lb: $22.05/lb

One of the most economical weighs to lose weight for sure. And based on my personal experience this battery has none of the issues of lead acid tiny batteries on this car.
Do you daily drive your car? Trickle charger?
