Taxi Garage 48v battery upgrade vs razor stock 36v.. how much better is it? 

Well the cart now has a 1000 watt 48v setup with the tg casters and some other small things but I’d say it’s about 2k including the price of the cart to fully build one yourself

I would say a solid 45 minutes to an hour and 20 depending how your ripping it its also slightly faster by a few mph
