place it on the charger right after a flight when it’s warm, it will cool down
as it charges. If it’s cool when you place it on the charger, it might
warm very slightly depending upon the charge rate.</DIV>

<DIV>They do warm up when charging, even at low rates. It's the physics
behind Ohms law that governs some of that. It may not be very
noticeable, but it is happening nonetheless.</DIV>

<DIV aria-label="Compose body">I would say "C" below: I have never had
a lipo pack get warm during charging. That's because i always charge
somewhere between 1.8-2.0 C. For my electric planes I buy enough
batteries so I do not have to hurry-charge in order to get back into the
air. I charge the lipos in my starter & glow igniter at home in
the shop when I have plenty of time. Now, in the interest of full
disclosure, I do not use $150.00 battery packs, and none of my electric
planes are for pattern.</DIV>
