<div><font size="2">Hey Carl/All,</font></div>
<div><font size="2"><br>
</font></div>
<div><font size="2">Looks nice, but would be nice to have auto disconnect of converter on low voltage -- of course that can be addressed separately, up line at the input of the dc-dc converter.<br>
</font></div>
<div><font size="2"><br>
</font></div>
<div><font size="2">Voltage monitoring by MCU (with suitable voltage divider) or display with one of those $1 LED display modules is handy, just thinking more about accidental leaving converter/load connected to battery.</font></div>
<div><br>
</div>
<div><font size="2">Maybe someone can shed some light on how many li-po packs have auto low-voltage shutoff these days.</font></div>
<div><font size="2"><br>
</font></div>
<div><font size="2">At first I was thinking about this converter being used with a 3 cell pack, wonder if it would work with a 2 cell pack?</font></div>
<div><font size="2">If so, at least the pi would die before the battery. You still would need to disconnect battery, but at least brain death would precede battery death.<br>
</font></div>

<div>Found these - should come in handy powering Raspberry Pi from a 3S LiPo pack. Haven't powered them up yet - but the specs look good</div>

</div>
<div dir="ltr">this one is a little smaller, with just Micro-USB out<br>

<div>it's also branded DROK</div>
</div>
<div>DROK sells a ton of handy modules like this - dc-dc converters of all sizes, I/O, control & display options. I've used them a bunch and haven't been disappointed yet.</div>
