Shipping/Warranty Battery Technology
At this time, there are two popular battery technologies; these are lead acid (PbA) and Lithium (Li) Batteries.  Each of these are discussed below.
 
Lead Acid

Lead Acid batteries are the most common type of battery; they have been used for the last hundred years.  The industry is mature.  Lead acid batteries are the most recycled commodity with about 97% of batteries being recycled.1  This compares to only 55% of aluminium cans.
 
Batteries for on-road EV use are made as 6V, 8V, and 12V batteries.  This allows one to choose different batteries for the same voltage.  For example, you can use 12-12V batteries, 18-8V batteries, or 24-6V batteries in order to have a 144V system.  The limitation is the space available and the payload capacity of the vehicle to be converted.     
 
The advantage of PbA batteries is:

•  Affordable
•  Readily available from reputable manufacturers
•  Available in different sizes
•  Recyclable

The disadvantages are:
 
•  High Weight to Power Density
•  Energy Density
