New to the store, and on sale for a limited time, BAK N21700CG-50 Cells. These are 5000mAh 21700 sized cells selling for $4 each!

They're manufactured in 2022, but are still tested for self discharge and internal resistance and have been randomly sampled for capacity. All cells delivered over 4900mAh and tested within 15mv of each other. All cells come with a full test report with serial number for large pack builds.

Get some while quantities last!

Finished pack. Some sketchy welds on this one. I need to get myself a better welder. But the balance leads are pretty clean if I do say so myself.
