This is battery related and I am waiting on my two extra on tues. and the other day, as I've been using the crap outta this one battery, I put it on the charger and it blinks the 4th led 3 times over and over, it's too hot, just used it, then it eventually charges and I get normal times, 21-23 minutes then the other day I noticed how warm she gets during charging I had unplugged it for some reason and decided to let it cool, before I topped it off all the way, well I think it took a better charge! Yeah, it doesn't make sense, but it was strong and lasted 24 minutes but I was doing a lot of sport mode that time. So now I have started cooling the batteries as they charge.
I mean does it not make sense? keeping them at a lower temp may mean it doesn't cut off as quickly as it does when its way hot, not warm but HOT
And then there's the quality of the "soak" being cooler makes the electrons slower, meaning theoretically, can't we pack more in? Or again, let the guys chime in.
I don't know, personally, I'd buy a little setup that cooled batteries with a small fan, like a tumbler fan.
I actually put a 2" fan nitro engine on a RC truck, made the duct out of a really small funnel, cut it up and it wrapped around the heat sink and pulled air thru via this fan running off a 9v rechargeable batt. Worked perfectly, I've force cooled amps, engines all kinds of stuff in my hobbies, computers with piezoelectric peltier pads with coolant.
I'm that guy I guess who feels that heat/heat buildup is best if not left to passive BTU transfer, but put a mechanical system to negate the problems caused by heat soak
