When BMW and Lg Chem team up for an LTO battery you know you can expect nothing but the greatest quality. These packs are rated for over 20,000 cycles.
Here are 48v 11ah BMW packs that use 20 LG Chem Lithium Titanate cells in series. You know the new vehicles that turn off and restart every time you come to a stop? Well these are the batteries from the 2019 BMW vehicles. We have opened and tested a few already and they test 100% capacity.
As shown in the other photos, you will receive the complete pack. You will need to trim around the edge as shown in the photos with a dremel to get the top off. There are also nuts underneath the battery where the 6 plastic caps are. Just pop off the plastic caps and loosen the nuts. With a little work you will get to the cells as a pack as shown in the first photo. The BMS is proprietary, you will need to use your own bms.
All you need is a 20s LTO bms and you are all set. Main positive and negative can be easily connected with ring terminals. The current busbars are designed for 130a continuous but can easily push 500+ amps on a pulse. This is truly a beautiful battery that'll likely last so long it'll end up in your will. 
Pack dimensions are 9" long, 6.5" wide, 7" tall.
If you are not familiar with LTO chemistry the cells can be fully discharged without damage and last over 20,000 cycles, Compare that to 300-1000 cycles for lithium ion and 2000 cycles for LifePo4. Fully charged each cell is 2.6 volts and fully discharged is typically 1.5v with the bulk of energy being stored between 2.6v and 2.2v. So fully charged this pack will be 52v and fully discharged can be set to 44v but can go as low as 0.0v if desired.   
The photo below shows the discharge curve of LTO cells.

LTO can be used even at -30 degrees Celcius.

Recommended max charge and discharge is 10c or 200a per cell. 

I'm sure you can take the cells out of the holder but I would recommend keeping the original busbars and spacing in tact. Its a professional connection that you can use. Just utilize the screw terminals to make your connections with wires and ring terminals. Makes this super easy, no soldering.
