  • Uh, no. A decent UPS is $300-500, and replacement batteries can be had for under $100, and if you keep the unit cool and clean, batteries should last 3 to 5 years.

    Also, if your UPS has 12V 7Ah batteries, you can sometimes find 12V 9Ah batteries in exactly the same form – so you get slightly longer run times after you replace the batteries the first time.





  • This is dumb anyway - nobody is going to pump 1MW into a car, the grid can’t support it, never mind a supercharger-style station with between 8 and 20 plugs. A 20-plug Supercharger needs around 1.5MW to serve each station with 72kW.

    And really, when I’m on a road trip, after 3h in the car, I need a break that’s long enough to hit the bathroom, grab a bite to eat, and stretch my legs. The car is usually charged to 90% in under 45 minutes anyway, even if I roll into the charging station at under 5%…
