Whats everybody seeing for battery temperatures during a discharge cycle ?

I cycled some 1900 nicads and at a 20 amp discharge they hit 175 degree's .They had peaked at 110 degree's.

Cycling 38's and 42's @35 amps must have some really high temps.

HOW HOT IS TOO HOTT !!!!!!!!!!!!

All kinds of info under search for BATTERY & BATTERIES

Also even more info in the product threads the matchers give you great reference tips and what they should be at for full charge and at discharge

At what point is damage being done to the cell ?

Or are charge temperatures more important than discharge temps for good battery life ?

The battery manufacturer's will never comment on these high rates we use in RC Racing.

I dont see the temp at the end of a discharge especially at 20A, they are never very warm..........

and I only discharge once then put charge in them to store them until next week....... Run in practice to discharge that pack then tray then charge to race....... 20A should not be creating much heat in the pack to worry about..............

Ditto.. after the last run of the day, the pack goes right back in the pit box -- no discharge.

The only time I discharge is when I need to run the pack a second time during the same day; and prior to the first run of the day (and equalize the cells on the tray).

My feeling are that whatever the pack is used it is subjected to lower loads in charging but higher loads in use. Typically they are charged at 3-6amps but subjected to loads of 15 -30+ amps in use, so pack is going to be warmer after use or discharge. I wouldn't be too concerned with temperatures unless a cell starts venting, shrink begans to melt or cell(s) start to get too hot to touch.

I was cycling some 2400 packs and two started venting, before I could disconnect the bulbs the shrink began peeling. Looks like one or two cells in each pack went bad.
