In my quest for weight savings I bought an Odyssey PC680 battery. The factory battery and tray is around 33-34 lbs. The Odyssey battery is 14.7 lbs. and the custom hold down I made for it is less than a pound. That is a savings of almost 20 lbs.
- 8″ x 8″ x 1/4″ piece of 6061 aluminum from OnlineMetals.com for around $10 plus shipping.
- 8M x 1.25 threaded rod
- Two 8M lock washer and acorn nuts
- Two flat head machine screws – I’ll need to look up the size again and update this
I don’t think it ended up costing more than $25 in parts to make.
