I had Shimano e8000 Merida e160 for a few years, now my friend owns it. I had two batteries, one came with the bike, other was purchased for around 300 USD (I have a friendly local Merida dealer, so the retail price might be closer to 430 USD). Both batteries were external and they are cheaper. After 4000 km and regularly switching the batteries, their health is 88 and 93 percent. I had one motor replaced that is still alive and used by other guy, while he was waiting almost a year for a new motor.
As for Turbo Levo I currently have, 700 Wh battery retail price is around 1100 USD, 500 Wh is around 850 USD. You might find it cheaper. After 1600 km I had my motor replaced, but it’s still alive. Also I have all harnesses for Levo due to terrible design of the motor enclosure and very bad waterproofing. Current battery health is 100% (but I assume it’s more like 97%).
Both motors were replaced according to Shimano and Specialized warranty policies: Shimano had some freeplay on crank shaft, Brose didn’t turn off power delivery after I stopped spinning pedals (it doesn’t spoil the ride, happens rarely, but if I spin eventually on a flat surface at 60 RPM and than accurately removing my feet from pedals, it can propel itself for a minute. New motor does the same, so I’ll claim the warranty after another 1600 km). But all of the above is not so awful, it actually barely tangible, so I just you it for a warranty claims, why not?
You should also count the wear and tear multiplication due to heavier system weight and greater torque. If you regularly clean and maintain your ebike, use 1.5 multiplication for wear and tear parts replacement. If you don’t, than use 2-4 multiplication. Also you should service your suspension more often. That’s how it is.
