Everybody loves more pow-wah! And Lithium Polymer batteries offer surprisingly dense power cells, and an increasingly affordable price.

These particular batteries are among the highest energy-density versions presently in production, and come with 55mm (2.17″) leads terminated with a standard 2-pin JST connector with 2mm spacing between pins.

NOTE:

• Do not attempt to charge these with anything but a charger specifically designed for Lithium Ion batteries.
• Shipping restrictions on Lithium batteries limit the quantity we are able to ship in one order.  We can only ship 8 per AIR methods.
