Lipo's & Cold Weather ?

[rchippie]

I called flightpower today & got the answer i was looking for. They said they do not recomend use a lipo when the core temp of the lipo is below 40 degress. They also said if it's that cold when your done using it they said put it right back on the charger as long as your pack is not over 100 or 110 degress, to keep the core temp up. They said this will also help lower the over all temp of your lipo in the charging process.

Well, I run a mm5700 on 3s in my losi xxx-s. It was about 40*f when I decided to go do some speed runs at the local(not really) huge parking lot. Just starting off my lipo(maxamps 3s 4k) was at 67*f. I radar-ed in at 33mph; then ran slowly tried to warm up the lipo and gradually hit 40mph. After, I decided to chuck the lipo on the windshield defroster in my car. Warmed it up to a nice 95*f then clocked in at a nice 57mph. Warming the lipos really do help.

I was talking to one of my boat racing friends(brushless of course) and he preheats his lipos to about 110*f before starting, supposedly it helps the electricity flow better....
