Thanks for the additional information. =
There used to be a tax credit for a conversion of 10% of the cost. I think
that is still valid, but I'm not completely sure. I bought my EV already
converted so the original owner took the tax credit.
I'm running Thundersky LiFePO4 cells so I can give comments about that.
However, I haven't had to purchase any in a long time. My general
impression is that prices of bottom-end lithium (like Thundersky) haven't
come down much in price, but the prices of higher performance lithium (like
Headway or A123) do seem to be coming much closer to the prices of
Thundersky. That is actually a good thing because they offer better
A good rule of thumb when sizing your pack for lithium is to assume that 1
gallon of gasoline will be about the same as 8 kWh of storage with lithium.
So, if you were burning 2 1/2 gallons of gas per day, you need about 20+ kWh
of storage. I added the plus because you have to add extra for heat (if you
use it) and don't want to drain your batteries all the way every day. With
my 13 kWh, I get about 50 miles range in a Honda del Sol.
Another item I should point out: Many people come to the conclusion that
they are driving electric because they just think it's the right thing to
do, but it isn't completely paying off. That has been a somewhat frequent
subject of discussion here. It may break even, but probably won't pay off
big, unless you're good at scrounging.
My case in point:
I paid $12K for a Honda del Sol already converted with lithium. I think I
got a bargain because this was about $2K less than the cost of parts, and I
didn=92t have to do the work! However, I also paid $12K for a car that wou=
have been worth $2K tops if it were still gas. I drive about 1K miles per
month, but my normal commuter was a Mazda 626 V6 that I've learned to drive
efficiently at 30-35 MPG. So, even with gas around $3.75, the Mazda only
costs me $117 per month in gas. That's about $1300 a year. =
If the del Sol lasts 10 years without a new battery pack, I will break even.
However, in the mean time, I'm driving electric, grinning every time I pass
a gas station, AND I get to drive a convertible! But, I'm probably not
I certainly don't mean to discourage you, but wanted to make sure you
realize where this could go. Sometimes I wish I had converted my car
myself. I think it would be a lot of fun. However, I've done enough work
on my car to feel like I did everything but the motor adapter. (See my
My dream would be to stuff a Warp 11 HV with high performance lithium cells
into a Mazda RX-8. That definitely wouldn't pay off. But it would be fun!
