I like that the battery is both marked with pulse and continuous discharge current.

This discharge curves are tracking just about perfectly and the cell can deliver 15A continuous.

The cell gets hot at 15A, but not too hot.

At 20A I had to stop.

Thanks for the test!

Nice, an honest and good new battery brand. If it is really a china produced battery it sounds really good quality.

Looks like it could be a LG HG2 cell, based on the discharge curves.

Hg2 overheats at 20amps like this one?

Blf has changed a lot since I've been here. Lots of snow flakes and easily offended over nothing. When the forum use to be great and people joked around and could take a joke. It's a forum it's not that serious. Let's make BLF great again!

Looks like the HG2 does get a bit less hot than this cell, but close. Not sure if that is due to a small difference in the thermometer attachment or an indication of something else.

The jumps in output was because my holder got damaged, not the battery. Yous has probably also vented.

I was prepared for venting at that temperature, but it didn’t happen.
