https://devzone.nordicsemi.com/f/nordic-q-a/127068/npm2100-li-fes2-ship-modeHello everyone, We are currently working on a project in which we plan to use the nPM2100 + NRF powered by two AAA Li/FeS2 batteries. We would like to use the nPM2100 ship-mode feature - the batteries would be connected to the circuit during shipmenten-USTelligent Community 13Mon, 16 Mar 2026 12:24:11 GMThttps://devzone.nordicsemi.com/thread/563325?ContentTypeID=1Mon, 16 Mar 2026 12:24:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f33db8ff-0acb-4690-a2a5-989084875696pdrzycimski_apo<div> <div> <div class="flex max-w-full flex-col gap-4 grow"> <div dir="auto" data-message-author-role="assistant" data-message-id="15317d38-6ecb-48a7-896c-e1ea4ea5586d" data-message-model-slug="gpt-5-4-thinking"> <div class="flex w-full flex-col gap-1 empty:hidden"> <div class="markdown prose dark:prose-invert w-full wrap-break-word light markdown-new-styling"> <p data-start="0" data-end="160" data-is-last-node="" data-is-only-node="">Thanks for the reply, and sorry for the delay.

So&nbsp;final compliance assessment should be confirmed with your battery supplier and shipping provider.</p> <p>&nbsp;</p> <p>Best regards,<br />Bendik&nbsp;</p><div style="clear:both;"></div>
