Tesla owners can soon upgrade their Tesla Roadster to a bigger battery pack that will offer up to 35% more range. It's not cheap, and will set you back $29,000. Tesla is already taking pre-orders, but requires a $5000 deposit. The new batteries are heavier and its not yet known how that will affect the Lotus-based Roadsters performance. The upgrade includes removal, upgrade and installation of a new power electronics module.

Upgrade your Roadster to a battery that stores roughly 40% more energy than the original battery. There is a slight increase in the battery weight but the total range increases over 35% from the original Roadster.

The price of the battery upgrade is $29,000, including all labor and logistics, which is equal to Tesla's expected cost. It is not our intention to make a profit on the battery pack. The reason the cost per kWh is higher than a Model S battery is due to the almost entirely hand-built, low-volume (only 2 or 3 per week) nature of Roadster battery packs. It also includes additional work to remove, upgrade, and reinstall the power electronics module (PEM.)

All removed battery modules will be fully recycled or reused if possible, and we will reuse many other components from the old battery. Batteries are currently being upgraded in Fremont, CA and we will need sufficient time when scheduling your service to ship and pre-position the needed parts to your local service center. Depending on local service team workload the upgrade will only take a few days once the parts are in place.
