Hi all,

Just wanted to share my latest project. I'm converting a 1973 fiat 500 R to electricity. I've created a blog that could help other do the same.

Please see luigi500.blogspot.com for more information.

Best regards

Nice blog. Looks like it's going to be a fun build.

Very nice, great combination of drive and car, I've been looking for a cheap Fiat 127 to pop an Agni into myself. The 127 is the smallest car you can actually fit a double bass into

What size battery pack do you think you'll be able to squeeze in?

Hi

I'm also interested to know more detail about the battery pack you think use and where you will fit it.

Hi guys,

My plan is to use 26 Lifepo4 150Ah packs. They would be located in the front and in the back. But as you know that involves alot of $ so I guess I will start of with lead acid 50Ah just to get everything up and running.

From the graph I have find, a 50Ah lead battery will be rated at 20Ah when you discharge it at 2C (100A). 100A x 72v is just around 8hp!

So, because the 50Ah battery will cost 600-900$ (100$-150$ each) and because you can only use around 15-20 Ah of those cells, if it' just to do some test, you can maybe keep an eye on small LifePo4 cells.
For example, 26 cells 38120s 10Ah will cost around 400-500$ and 26 cells 40160s 16 Ah will cost around 700-800$.
Maybe this 20Ah: http://www.ev-power.eu/?p=p_46&sName...o4-cells-(3.2v)

I used 7 Kg of headway 10 Ah in my Smart fortwo to do some test. That worked great.... for short travels at low speed!
It's just an idea!

Hi yabert!

You got a good point. Testing with low amp lifepo4 also gives me a chance to learn more about bms and charging. Ideal would be to be able to use the cells from test in parallel wither real pack, but i guess the discharge C would be a problem.

What about pouch cells? Those are minimal in size and weight, what is the draw backs?

What are your recommendations regarding bms? It would be nice to have a bms and a charger that can communicate.

Best regards

by the way, on seats you can get very light aluminum shell seats in either high or low back by Kirkey.... at SummitRacing, or direct from Kirkey. I also found some nice vintage design seats by Corbeau.
