Tesla Model X Towing 5,000-lb Camper: 600-Mile Road Trip

My concern is the speed at which the pack is drained - nearly 1C. This is very hard on a big battery pack.

Batteries from lead acid to lithium are used in plenty of heavy duty applications, but they're sized for closer to C/4 to C/12 rates.

That's why I mentioned 1000 kWh - at that size, we could tow a regular commercial travel trailer and maintain say, a C/5 rate of discharge. Ideally you'd arrive at a campsite and charge overnight at C/10 rate. Not being blasted by a supercharger at 1C+

So far semi regular supercharging hasn’t had a big affect on Tesla batteries. Having said that most charging is fine at home sooooo...

I would think most SUV’s won’t see batteries bigger than 100 - 120 KWh and even vehicles like Cybertruck and Hummer won’t go much above 220-240 KWH. When they start to shoot for the 3/4 ton or 1 ton market that might change someday but I haven’t seen anything like that on the drawing board yet.
