You mention in your video 'similar dimensions' :
LEV50: 171mm x 44mm x 98mm
CATL93: 172mm x 42mm x 90mm
SVOLT90: 148 mm x 39mm x 102mm (short and high)
Extensive modifications are required if you want to use SVOLT90 for I-Miev/C-Zero/iOn upgrades, CATL93 are a much better fit but 'beggars can't be choosers'; have you any datasheets for these cells?
