For a cell to charge properly it needs to reach its peak detect and temperature range naturally. So by cooling the pack down with a fan your not getting the desired chemical reaction thus not getting a full or proper charge.

Danny, I always thought heat on any battery was bad. So I normally undercharge my batteries (ie. 3600 Mah in a 3800 pack), my batteries never got a aboce room temp, which I have always though was a good thing? or am I wrong.

I would go with either the wave tray or the Tekin,the .09 story is just that, a story,the Tekin will go down to .05 which is fine, but as far down as I want to go.

I've been using my Integy 20amp tray for quite awhile with no problems. Your pack should not be discharged below 5.4v for the entire pack 0.9v per cell. If you use it more than once a day let it cool to room temp, then you should put on a tray for a few minutes before charging.

Integy also makes a 30 amp tray

And a 30amp dumper

Hope this helps

If your looking for the best performance out of any cell it needs to peak in the 130-140 farenheit range. Todays cells can easily handle that temp range and will perform at there best at that range.

I know this is a very relative question, but what does 135 degrees feel like to touch? Should it feel hot, but you can still touch it, or slightly warm? Or too hot to touch?

It should not be too hot to touch. Keep in mind that you are already around 98 degrees.

At 110 they will not give the maximum performance. At 150 they will perform well but could potentially hurt the life expectancy of the cells.

For best results run the packs as near to the end of the charge as possible.

Mainly, the performance is going to SUCK!!

Secondly, and maybe Danny can correct me if I am wrong, but you may risk acctually overcharging the pack. Since the pack is cold, but charged less than 24 hours prior, it is still relatively well charged. But, the charger probably wont detect a peak untill a relatively large amount of current has passed through the cells. So, you could overcharge them. AND you want them to be warm and right off the charger right before your race.

Whats better, a day old cold donut, or a nice fresh warm KrispyKreme??
