Default Dumb 2400 Question

I bought 2 six-cell SMC 2400 packs a few days ago at an exeptional price and I have a question. I've used only 3000HV and 2000's in the past. When cycling them, I charge at 4.5 amps, wait 30 mins, and discharge at 20 amps. (I race stock.) The batteries get very hot during this, I've only done it once on each. My HV's and 2000's don't get nearly this hot, am I doing something wrong or is it just how these batteries are? I use Orion platinum bars and Trinity R-minus connectors, and I solder well, so I don't really think it's a resistance thing. Any ideas?

I just measured the temp of the pack, it was over 130 degrees F. That's not good....

It doesn't sound like you're doing anything wrong. If the other batteries don't get hot like that then maybe try something different. What are you using to cycle your packs? Were the 2400's used or new?

I use an old BC112A to charge and 10 2 amp light bulbs to discharge. I'll run them in my car and see what happens. The packs are brand new.

Is it 130F after discharge?? if so and you are not blowing a fan on it during discharge....then it doesn't sound too excessive. If you are getting 130F after charge...then you are in trouble!!!!

dtm- they got to 130 after discharge. I'm really surprised because both my 2000's and HV's are only like 80-90 F after discharge. I guess I'll just have too be careful. Thanks for the help!
