<div>My personal experience is as follows.... </div>
<div><br>
</div>
<div>I charge 90% of all my packs at a 1.5 to 3 c charge rate. I religiously make sure the packs are at storage voltage when not flying, and i make sure I always refredgerate them while not in use. This has always worked well for me with a 99.9% success rate.
I have some 8+ year old packs that still balance great, and have 300+ cycles on them. The resistance can be a bit high, but still within reason. I have also had good luck taking "puffed" packs and refredgerating then for a week, let them thaw, and then perform
a few slow cycles on them. Most of the time, this gets then back in the game. I will also never buy another high dollar pack such as Thunder Power or Hyperion. I never have had the amount of issues with the lower price packs, and they don't turn into baseball's
or watermelons like Thunder Power or etc.... To me it's very dissapointing to buy 1 pack for x amount of dollars use it twenty times and pitch it, turn around and buy multiple x packs for the same price of the 1 x pack, and have many seasons of happy electrons. </div>
<div><br>
</div>
<div>Just my two cents, and only that ! </div>
<div><br>
</div>
<div><br>
</div>
<div>Respectfully,</div>
<div><br>

<div>Apparently you guys never put them on charge when they're hot!! Then they definitely cool down while charging. :)<br>

<p class="x_MsoNormal">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.<span style="font-size:12.0pt"></span></p>

none of my electric planes are for pattern.</span></p>
