In fact, the "battery gauntlet," developed by Aptera co-founder Steve Fambro, turned away more than a dozen different suppliers and chemistries before the team arrived at the final solution.

[FONT=Century Gothic, ITC Avant Garde, Arial, Helvetica, sans-serif][FONT=Century Gothic, ITC Avant Garde, Arial, Helvetica, sans-serif]Today, the production battery used in the Aptera 2e consists of more than 300 individual, prismatic pouch-type, high-power lithium ion cells, which are based on phosphate chemistry and configured into several modules. Each module contains cells carefully connected to provide an optimal operating voltage. The complete battery pack, as shown above, provides the 2e with an excess of 200 volts for the traction system. This particular production intent battery pack will make its world premier in our Xprize competition vehicle.[FONT=Century Gothic, ITC Avant Garde, Arial, Helvetica, sans-serif] [/FONT][/FONT][/FONT]
[FONT=Century Gothic, ITC Avant Garde, Arial, Helvetica, sans-serif][FONT=Century Gothic, ITC Avant Garde, Arial, Helvetica, sans-serif]The unique design of the production batteries allows them to have an extraordinarily long cycle life. Most competing lithium ion battery technologies advertise good performance and operation of up to 1,000 to 2,000 recharge cycles. Test data demonstrates that the Aptera batteries should deliver at least 1 and ½ times as many recharge cycles, even when exposed to abusive conditions. Our selected battery technology can also deliver aggressive depths of discharge, so you don't have to worry about damaging the battery pack.[/FONT][/FONT]
[FONT=Century Gothic, ITC Avant Garde, Arial, Helvetica, sans-serif][FONT=Century Gothic, ITC Avant Garde, Arial, Helvetica, sans-serif]Lastly, our Aptera battery pack does not use a complicated cooling systems. By avoiding such systems, Aptera is able to prevent considerable expense as well as the wasted energy associated with operating them. This factor was critical in our selection of this battery technology and reinforced our goal to assure we are putting as much of the vehicles energy toward driving use as possible.
