You can just get a 48V 15Ah version, and add Reention Dorado DP9 battery (48V 24.5ah), which can be purchased from Jenny.
Now you have 48V 39.5Ah total.

If you're not happy with 48V 39.5Ah, you can add rear rack battery (additional 48V 31.5Ah) to make it 48V 71Ah
The rear rack battery looks something like this, I'd suggest you asking Jenny first though.
This case holds 117 cells, so if you ask Jenny to assemble it with Samsung 35E, it will be 31.5Ah.
