A California company with 5 years of doing plug-in conversions for Prius is now offering a 3kWh modular add-on battery pack for the LEAF. These are perfect for cars losing capacity, or for those times when you just need a little more range and there's no place to charge at your destination. Easily transferred to and from your car.
Plus, they are fully equipped with their own high tech BMS, charger and state of the art Lithium Manganese chemistry cells. Two year warranty. Shipped to you and easy to install. The cheapest version just has a simple inverter and J1772 plug to charge your car. About 10-12 more miles per module. About 60 pounds each:
Each pack is approximately 9" wide x 14" deep x 11" high. You should be able to fit 4 of these packs in the trunk, for 12 kWh total (approximately 36" wide x 14" x 11" high) for 40-48 additional miles.
It's not yet on their website (sorry, I didn't get a picture yet) but you can contact them at:
