Re: Motortrend article with tons of info about Tesla’s Cybertruck

Maintenance... As i said, many manufacturers offer “capped price “ servicing for the duration of the warranty period ( 3,-5, even 7 years !) for example , Toyota service fees are capped at Au$140 (US$100) per year. Also its common to be offered “free servicing” when negotiating a new car sale If yo...

Solid state battery question

Hi,

I just watched a video with a lot of information on solid state batteries.

They said that an advantage of solid state batteries is that they don’t require a separator because the solid electrolyte serves thank function.

How can that possibly work?

Thanks 🙏!

Unless Elon also pulls out next gen batteries I don't expect much from this quad in terms of range at least.

He will. Stay tuned for battery day in about @4-5 months.

Re: How can I get 110ac from a ZENN runs at 69-80v dc

Change of plans. I am now planning on using inexpensive EVs for DIY powerwalls. I think the cheapest way to do DC to AC conversion is to use 12v DC to 110v AC inverters. So now I need a recommendation for an affordable 72-96v DC to 12v DC converter. I can use the ZENNs 12 v dc output if its sufficie...

How can I get 110ac from a ZENN runs at 69-80v dc

I can’t find an invertor that converts 70-80 volt dc to 110 ac. Lots of units that do 12-48v dc.


I need to run a snall boiler and the associated pump that supplies radiant radiators for a small house.

I’m cold due to a power outage 4th day.

Re: Recommendation wanted kick scooter or escooter for someone with ALS

My wife is correct. I’m too weak, to ride a push scooter!

Now I’m planning to buy an electric trike. I’m hoping that someone here will be able to recommend a good alternative. An very important factor is excellent low speed throttle control.

Thanks!
