So far, this is the battery I plan on using. I will attempt to cram 51 of them into the car. 17 in the tunnel, and 34 in the front compartment. I would also like to use 8 of them for accessory power.
price for 1 battery is $143 plus $95 for shipping. I can get a discount for a large order. (I'll get details as I get closer to ordering)
A 156Vdc BMS is $600 and a 156Vdc 30A charger is $1600. I will review these items in detail later.
The size of this battery is slightly larger than the original tunnel assembly. I will widen the tunnel minimally by 1" and raise it by 1/2". Once the front assembly is done, I'll redesign the tunnel assembly in ACad, then get the parts I need.

These are indeed well priced. Something that you need to consider is the current output these batts have, and past 'issues'.
This is what I found with only a quick search...
********************************
TS-LP90AH cell, rated at 90AH.
70-80 AH capacity, but only when quite warm.
10-20 AH if they aren’t warm.
Hi internal resistance, so they heat up with only a 18A draw. Likely to overheat quickly at higher draws.
NO CUSTOMER SUPPORT WHATSOEVER
Not a chance of meeting their rated max output current.
Can only charge slowly (20A or so max). Some cells overheat quickly above that rate, some just won’t accept higher rates without going over voltage.
Wildly inconsistent quality control. Cells vary by quite a bit.
********************************************
It sounds like they are getting better with quality these days, but I won't be getting them.
