Default Cooling battery info

Recently watching a 1/10 and a 1/12 race in Italy I observed both scales using battery cooling fans while charging and discharging. The DVD I was watching is a little old but is it good to temp control via using a fan or just use a temp connection to the charger ?

I figured if it was done there must have been a reason, does anyone know ??? I told my friend that was watching with me that at the track I dont see anyone doing this so I dont either but his debate is WHY, what was the purpose, he is about to start 1/12 scale electric and he wants to start buying gear...

Default ambident temp too high

I guess what u saw is the world race in italy. It was too hot to reliably charge battery at that time,may be that is the reason. From all I read from various batteries site , they all said NO FAN during charge. the charger won't stop if u use fan because it can't detect the peak volt.

He went home to spen d some time with his family but I will call him in a few hours and pass the info on. I normally see what the faster guys at the track are running and follow suit. This is what I was telling him but when he saw the fans he thought it was something to have...

Whoa. Is this true? Delta Peaks are a function of battery temp? Can someone confirm this? I guess it's not such a big deal but now I am curious.

Cooling your packs during charge or dourin discharge raises the Internal Resistance and decreases runtime. THe much more sucks warmth from the packs, doesnt blow on them.
