Hi all I am starting on my first EV project. My son and I are converting a=
1991 Ninja motorcycle. Lead batteries are planned, but I am curious of th=
e advancement of LiIon, NiCad, etc.. and wonder if I should go that route. =
In thinking about this, what specs are important? RC =

I think I am getting filtered because I have replied
twice to your other post but have not seen it posted.

Here is it reprinted and filtered to the essentials:

""Hello and welcome Robert,

Next time, please put a header on your question or
this could have been missed. It originally said (no
subject).

Car batteries are not intended for the deep discharge
that is required of electric vehicles. In simple
terms for a DC motor, voltage equals speed and amp/hrs
equals capacity of discharge or distance. What I
recommend is you look at THE LARGEST collection of
electric vehicles in one site otherwise known as the
evalbum.com (specifically
http://www.austinev.org/evalbum/type/MTCY ) as
provided by the fine members of this mailing list,
compare existing builds with their batteries so you
can get an idea of what to use and actual performance
as told from an owner's perspective, and then come
back asking about batts...........

Back on topic, also you can check out
http://electricmotorcycles.net and the mailserver
which is an off shoot of this list. """

Now onto your other question, For Lithium look at the
evdaytona on the album and its performance and also
electricmotorsport and its lithiums. For any version
of Lithium, it is advised that you also invest in a
good BMS (battery management system) to control the
discharge rates and preserve the batteries. This adds
further cost in addition to the higher costs of
lithiums. NiMh also needs a BMS to preserve the
batteries.

How deep are your pockets? Even cheep LiIon batteries will cost you
several thousand dollars and then another couple thousand for a charger
and battery management system.
Saft NiCads are a little cheaper, but will still cost quite a bit for an
approved charger. If your charger doesn't meet Saft's approval they won't
honor the waranty, they might not even sell you the batteries.
As I recall Saft batteries cost about $500 each and they can't handle very
high currents. You might run into problems getting enough on a motorcycle
to get decent performance.

So, unless you are planning on spending a bunch on this project, my
reccomendation is to stick to either Optima YT or Exide Orbital sealed
Lead-Acid batteries.
