I’d be tempted if I had £4.5k, it’d be unusual for both of us in the ‘spoon house to be doing >100miles in a day. And I’m getting through £200 in petrol each month so £110 to lease a battery for unlimited milage seems a bargain.
That and no congestion or LEZ charges now or in the future. If you work in London that could save a fair amount.
They are all car specific.
Depends how far you go in stripping down, apparently inside they’re just a load of 18650 cells, so if you’re that way inclined you could re-build one. A colleague stripped and refurbished (by charging the cells individually on a smarter charger) a prius one when it failed (NiMH not Li-ion, but the same principle).
For a 2nd car they look like a reasonable option if most of your journeys would be in range. Battery life seems better than feared, but if you do need to replace them it could be pricey.
That’s the advantage of leasing the battery, you never need to pay outright to replace them.
