Battery extender (new, legit) on eBay at a discount

You seem to use a lot of power on your rides :) Like in #itridesitselfebike? FYI, the Specialized 320 Wh main battery is just 6.66 Wh but you would easily ride for 40 miles, were you pedalling an SL e-bike :)
As far as power usage, Im not sure how much Im using. My longest ride lasted most of the day doing errands in and around the two towns that I live between. Fully loaded with dog, of course. The 5 bar battery indicator on my display didnt even drop a single bar. I know those type of charge indicators arent terribly accurate when it comes to lithium batteries though. The bike display does measure ah used per trip, but Id have to navigate a menu to see it and i keep forgetting. Math tells me that I should have 2880 watt hours to play with though, and thats a whole lotta watt hours!
