This is how you remove the Specialized Turbo Levo SL 1.1 motor and internal battery. Useful if you ever want to just use the 160Wh Range Extender only, saving 800g weight, or want to be able to put the bike on an aeroplane where you may be restricted by the 320Wh internal battery.
I've had a few rides on just the range extender only and it works really well. As it reaches the last 20% power does drop off considerably, but thats understandably as it the battery voltage drops.
Please note, that riding without the main battery could risk water ingress in the main battery connector if not correctly sealed. With 2 open battery holes located on the down tube I'd recommend that you exercise caution in wet weather. Although the battery connector can be sealed with plastic wrap / tape, there is still a chance of water ingress as it is no longer connected directly to the battery with the water tight plug. The motor is water tight. Marine-grade seals mean the motor is dust and waterproof to IP66 & IP67 standards,
