...mass disadvantage is 10% or 20%

Tesla has batteries from 1000 to 4000+ pounds.
10-20% is a huge weight gain especially for a battery that provides less output.

Right now, I'm not an EV fan, yet here I\we are talking about it.

I adiosed my gas powered lawn mowers for battery operated mowers - one riding one walking self-propelled.
Still hanging on to my oil\gas powered snowblower cause i haven't seen an electric that could take it's place...yet.

10-20% is a huge weight gain especially for a battery that provides less output.

No doubt - but that’s on the weight of a given storage-capacity, not the whole vehicle. When cost is a sensitive parameter, as in a cheap vehicle, you have to give somewhere else and vehicle performance is bound to be what suffers.

Again, if the battery is stationary - and that is a very useful application - even 20% heavier doesn’t matter a great deal. Because of the great and growing cost-effectiveness of solar panels, cheap stationary storage of solar electric energy is a very useful commodity.
