LOL... I have lipo "ovens" already. I've used a crude one for the last couple years. Now I've been working on a nicer one that's marketable. There might even be a couple of them at the Chi Town Shootout next week. I suspect we will see a few such devices on the market eventually.
IMO these should always be used when racing in cold environments like some of us have in the winter... whether outside or an indoor track where it's hat and gloves temp. You should keep lipos at least at a nice room temp, and @100 degrees makes a noticeable difference over room temp. But now the hardcore racers will want to use them all the time to get them to 120-140 etc to get even better performance.
For a long time, warm lipos was a little secret some of us knew about. Now everyone will know. Thanks Danny, I think... lol
Discharge graphs have shown for years (like found on rcgroups.com) that voltage (performance) is directly related to temperature. Hot batteries always work better and lipos are no different.
Hopefully this will put and end to guys intentionally overcharging lipos, and pumping huge amps into them, etc... thinking it's the magic bullet.
So SMC gets two thumbs up from me.
