BYD 24v battery breakdown

I just finished up a quick break down of the BYD 24v battery from https://www.batteryclearinghouse.com/.  These batteries are stout, well designed and HEAVY !

I fast forwarded thru most of the process, but I slowed back to normal speed in some spots that most of us have questions about.  If there is not a significant reason to disassemble the battery, I would advise against it.
It appears that the PCB’s are for monitoring the cell voltage and not balancing, but I can not be sure of this.  They seem to be too thin to use for balancing.

I drove to Battery Clearing house and met with Guy, they had about 200 or so in this location and more in their other warehouse .  Guy said that they normally ship next day, and they have plenty of stock.

The batteries have 2 posts for positive and 2 posts for negative. The bridge between posts are not a solid bar, they are made up of about 100 layers, I presume to allow for expansion and contraction.    

In essence, this is a box with 8 batteries in series and two heat sinks.  To my knowledge no one has been able to gain access to software on the included BMS, so plan on purchasing one.

Cell voltage was 25.5v upon arrival and the cells were within 1/10 of a volt.
