My Dad has been converting a 96 CC DS to hold 8 - 6 volt batteries. In addition to the conversion, he has lifted it, redone all the accessory wiring and other things. Today was his first test run from Chatham to Mallory. It does not have the 8 new batteries yet, but he has two extras in there to test weight, fit, etc.
Here my lab assistant Caly checks the legroom. If you look to towards the rear behind the seats you will see where he installed the batteries.
Here is a shot from the back. Once he is done, with battery housing cover and the basket on, I suspect you will hardly notice. I told him to build a nice wood cabinet with fake doors and a lock so it looked like under basket storage, but he bought and painted a $2 plastic bucket for the first pass.
I will integrate some detailed pictures later in this thread. It is very impressive, but what else would I expect from my 78 year young Dad
