<div style="direction: ltr;">Hi Jarrett,</div>
<div style="direction: ltr;"><br>
</div>
<div style="direction: ltr;">I took the equipment spec sheet for the prismatic line and this is what it said:<br>
<br>
<i>With each 16 kWh Sol-Ark system using 16 prismatic 314Ah cells, and a prismatic line capable of handling approximately 95 cells per minute, the daily output for two 8-hour shifts can be calculated as follows:<br>
<br>
Cells produced per day: 95 cells/min×60 min/hour×16 hours=91,200 cells&nbsp;<br>
Modules produced per day: 91,200 cells/16 cell system=5,700 modules<br>
This is the theoretical maximum, assuming assembly processes downstream (module, pack, and testing) keep up with cell processing, with no significant bottlenecks. This calculation is valid for the specified 16x 314Ah cell configuration per system. Actual output
 may be lower based on process specifics or technical constraints in the pack assembly area.</i></div>
<div style="direction: ltr;">&nbsp;</div>
<div style="direction: ltr;">The numbers below I double checked with Kevin from what I gathered on AI as well.&nbsp;</div>
<div style="direction: ltr;"><br>
</div>
<div style="direction: ltr;" class="elementToProof">1) Pack/Module integration time: 1-3&nbsp;</div>
<div style="direction: ltr;"><br>
</div>
<div style="direction: ltr;">2)&nbsp; Testing &amp; Aging Cycle duration: Our machines do EOL (End of Line) testing.&nbsp; For a full charge discharge cycle I would say 24 - 72hrs.&nbsp; I think we can get away with doing 24hrs on select systems for random testing/QC.&nbsp; Brian
 thinks we will need to do every unit for the first few hundred or so to get all the kinks out.&nbsp;</div>
<div style="direction: ltr;"><br>
</div>
<div style="direction: ltr;">3)Quantity &amp; Timeline for production: 1GW in 365 days.&nbsp; That is producing 171.23 units a day.</div>

Thanks Jordan, do we know the estimated:<br>
<br>
1) Pack/Module integration time? (hours or minutes to assemble the BMS &amp; additional components)<br>
<br>
2) Testing &amp; Aging cycle duration (hours or minutes the module needs to be tested)<br>
<br>
3) Quantity &amp; timeline for production deliver? Roughly speaking - this will help with confirming the labor rates<br>
