Thankyou for your demonstration

[@flyonbyya]

Seems like they wouldn’t have specified such a high rated discharge rate given the sag at 9A

Can you please share your testing data - I work with cell aging simulation software and would like to know more details for possibly creating a model (digital twin) for this cell within the software

[@ThunderheartReviews]

Hi Steven. I don't test the cycle life. This particular cell i tested 3 times at each discharge rate.

[@Uglydollsrises23132]

@@ThunderheartReviews Okay, thank you.

[@chittlingwhittles1198]

Can you please tell me from your experience how consistent QB cells are in terms of internal resistance, capacity and discharge curves?

[@ThunderheartReviews]

It depends on the cell. Some are highly consistent, others are not so much but i didn't have a QB cell which would show really bad results. Especially the new models always show higher capacity than declared which i like a lot.

Ok I’m just wondering how the 18650s would do in a pack with a cheap BMS Thx
