Electric vehicles are like Bic lighters, once they are out of juice you throw them away.
I have a friend who made a jig to refill those lighters from a two pound Coleman profane canister.
And....I made a jig to fill the two pound canisters from a 20 pound bottle.
OMG the car is only 8 years old, my car is is 16 years old and I had to change the clutch which was $800.00 other than that just timely oil changes!! $22,500 after just 8 years OMG!!!
