how to test LOTS and LOTS of batteries?
We have 420 panasonic 2800mAH 3.7V 18650 batteries, which we plan to use in a solar car. I was wondering if anyone is aware of how to many of these at a time. Many of the commercial "capacity tester 18650" online appear to only test a cell at a time. This would take way too long.
We need to ensure the cells we are connecting together are well-matched in terms of ESR, capacity, leakage, etc. So is there any solution that exists to accomplish this task?
