freezing batteries
 
Since batteries dont like heat..would it be ok to put them in the freezer, or in a cooler before running them or making a new pack..or would the drastic temp change do more harm than good??

if you freeze a cell before charging the voltage will be increased and you'll get a false peak.......

I never tried to freeze my pack after charging just because the earlier you run your pack when it's charged the best performance you'll get, this is why most matcher suggest you to repeak the pack if it's sit for more than 15 minutes after charged....

it will raise the IR in the pack! horrible idea bro..and who told you batteries dont like heat? the new GP's dont hit the track unless they border on 140 deg... turn up the heat baby! check out smc's web site for all battery care!

And the last question in his post can be answered with an emphatic YES. such sudden extreme changes in temperature IS VERY bad for a battery. It could concievably cause its casing to be damaged, if it's bad enough. And to say just a bit more on what Salvadori & UCHEATULOSE said, a battery relys on a chemical reaction to handle electrical energy, & when temperatures are lower(like freezing levels & such), it'll slow down the chemical reaction inside the cells, thereby reducing the amount of energy the battery can store or discharge effectvely. Think of it this way, these sme principles apply to automotive batteries, & that's a part of why those manufacturers label them with a CCA number(stands for Cold Cranking Amps), because what those batteries can normally supply in warmer weather is MUCH higher than what they can suuply in cold weather, so if your car's battery is weak enough, then in the cold it may not be able to start the car. And the same also applies to R/C cars(though not to the same degree), but hopefully you see my point....:cool:
