Investment is the right question.... it is common to underestimate a "swap" of any kind let alone an e-swap. Donor, + de-ICE'ing, + any resto mod work, + system + installation... We are aiming to offer a variety of range and power options and also develop as we can mounting solutions....
For now we provide the turnkey systems and offer a few range/pack size options. The 173 is a bit small for these and twin 173's is a bit pointless in our eyes.. We did provide the system for the Downy show but that is boiled below basic in what we would suggest for a day to day.. The 413 with a direct drive to TC is what we are doing in the next couple.... The 40's are looking at about 65-70 kWh packs and system costs currently running $70-100k. Aiming to bring costs down with ramped up production in the coming 2 years. These are complete wires systems including the options and additional components like powers HV steering, HV- AC, HV coolant heaters, VCU, BMS. etc. About the only OEM level system with all new components minus the "donor". The 413 is a 800V system.
Now you can start kicking some math (money, time, things) around that is reality

This year will be fun as we have the 60, the 40, and a couple client 40's on the deck. Will keep posting as super cool things are coming from behind the curtains in short order!! Appreciate everyones interest and open discussions!
