Hi Nathan and Jordan,

Please see the attached inverter specification sheet that we plan to pair
with the Non-FEOC battery solution. I recommend paying particular attention
to the battery input data section. This will be an important discussion
point with our CEO, as we aim to achieve a 1.0C rate or as close to it as
possible. That’s why the earlier questions regarding BMS capabilities and
customization will be critical to address.

I’ve also included a CAD file of the system. We’d like to explore a gutter
solution to simplify installation and achieve a cleaner, more integrated
look. This could require adjustments to the enclosure design, including
additional terminals — one set for inverter or bus-bar connections and
another for parallel battery connections. I don’t expect LBC to have a
finalized design for these yet, but I wanted to flag this since it will
likely come up in discussion with our CEO.

(Let
me know if you have trouble accessing)

Lastly, I want to reiterate that the goal of today’s meeting is to review
LBC’s capabilities and cell sourcing for both FEOC and Non-FEOC solutions.
Our intent is to develop a Generation 1 Sol-Ark solution that can be
brought to market, while also setting the foundation for future generations.

Looking forward to the discussion.
