Hi, I had my first battery dump in a while yesterday. I was looking at the data and the temp was getting high while dissipating/dumping. Is this anything to be worried about?

Temperature is from the probe on the BMS board in the battery, not the cells themselves. They usually run pretty warm - especially a single battery on Gen 2 or 3.
Seems fairly normal temp range to me.

I have never seen battery temperatures that high in our system. For example, today, with a 22C ambient, the highest battery temperature reported after 2 hours of full charging current was 32C. And that's pretty normal for us.

wilfleek depends how many packs you have and which gen.
If on Gen 1 and 2 packs then each battery BMS is only really doing half the work ~ 1300W/25A
A single 9.5 on a Gen 2 / 3 pushing 3600W/70A for hours will get a lot hotter.

AC3 and 2 x 5.2w, so they are each seeing around 1500W.
