Will respond more clearly tomorrow morning.  I want to make sure Nick is
included with the communication.

The BMS could handle 300A for 15 seconds.  It is a heat dissipation issue
from FETS.  It can be programmed in back end software.

Susan and Wilson have new relationship together so their working
relationship and knowledge needs to be communicated.

Try not to be persuaded from GSL to accept their parameters.  Sol Ark is
just setting their battery management system and cells to a better quality
which will lower their after sales support and align the battery for better
performance and balancing.  Chinese have very narrow scope and we need to
be specific on laying out our requirements for the project.

Let’s discuss tomorrow morning.
