Trojan Battery




Optima Yellowtop

Batteries can be the hardest item to decide on for a new EV. Do you buy huge, deep cycle batteries for the utmost in range or spry, lightweight “new tech” batteries which cost more but promise snappier performance?

Our first EV started off with twelve Trojan SCS225 deep cycle batteries. Even though I treated them rather badly (a charger failure and a missed watering) they lasted for three years. The next set ended up being a slightly cheaper set of generic deep cycle marine batteries and they barely lasted a year. After that it was back to the SCS225.

For longer battery life a 12v deep cycle isn’t the optimal choice. It is better to go with an 8volt, or better yet 6volt deep cycle battery, which are rated for 300-500 80% discharge cycles.

Here’s a list of FAQs, information, and suppliers.

Renault 4CV to 4EV Conversion · 19 August 05

Renault 4CV

Terry Vessels is underway with a rather unique conversion, as you can see from the photo. It’s a 1959 Renault 4CV and looks to be quite the project.

I like his three step approach:

  • Get it working.
  • Get it working well.
  • Customize.

He’s also working on other projects in his spare(?) time.

Good luck Terry!

Solar Prius Project · 19 August 05

Toyota Prius

Lapp Renewables has embarked on a project to make a Toyota Prius more of an EV.

It will be interesting to follow Steve as he finishes the projects and starts collecting hard data. Of course we are approaching Winter here in the northern hemisphere so full-sun testing won’t be for another six months or more.
