First, it should be noted that PV panels on an EV are a special case
solution. It's usually better to put them on a fixed structure

I won’t jump into a technical argument about the suitability of one battery
type over another for a particular application, but it never hurts to think
about the environment when making decisions. I’ve several several years working
with communities poisoned by emissions from battery processing

It appears that Lawrence has already made up his mind, so in a few years'
time we can ask him how that Leaf 12v lithium retrofit worked out.
In the meantime, other folks here now have good, useful information and
advice from two knowledgeable and experienced engineers and EV builders, Lee

The leaf battery behaves much like the 12V Prius battery in my experience.
They both seem to fail earlier than they should, but when should they fail?
That is "opinion". The failure mode is different, probably because they
don't fail by not turning a started motor? So you don't know capacity is

It depends on your goals. Sunpower cells can produce the most power per

To make solar panels work on an EV they must be specially encapsulated Sunpower
cells. No panels. The area should be 5-6 Meter squared. Should yield 1.5 to

In automotive parlance, the dreaded "load dump" occurs when the
