I understand that maintaining 300A for 15 seconds may not be feasible, 15 seconds is a long duration, and most appliances don’t require that much ramp-up time. Could you share any data regarding the peak power capability for a shorter duration, such as 10ms or less?</span></div><div><span style="color:rgb(0,0,0);font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif;font-size:14.6667px"><br></span></div><div><span style="color:rgb(0,0,0);font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif;font-size:14.6667px">I reached out to Susan and Wilson on this.  The 16kWh battery can support 200Ah burst but not continuous.  The 314Ah cell is a .5C charge/discharge so they don&#39;t suggest continuous over 157A.  </span></div><div><span style="color:rgb(0,0,0);font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif;font-size:14.6667px"><br></span></div><div><span style="color:rgb(0,0,0);font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif;font-size:14.6667px">I want to confirm with you and see if you have any thoughts or ideas before I respond.  </span></div><div><span style="color:rgb(0,0,0);font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif;font-size:14.6667px"><br></span></div><div><span style="color:rgb(0,0,0);font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif;font-size:14.6667px">Thanks,</span></div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><p style="margin:0in"><span style="color:black;font-family:Arial,sans-serif"><br></span></p><p style="margin:0in"><span style="color:black;font-family:Arial,sans-serif">Jordan G.
