Perhaps many of you have noticed that this 18650 is the most common Li cell on the market, but there is a myriad of manufacturers, amp hour ratings and prices. It is a mine field. I have spent several hours researching the trade-offs of high capacity verses durability and several things have surfaced.
1) You cannot believe any manufacturer's ratings in either mah or (number)C, because they are often bloated for marketing purposes unless the tests are performed by a 3rd party.
2) No article has directly addressed the question "Is it possible to have both higher capacity without trading off durability (battery cycles)". If yes, how do I discriminate?
Everybody wants lower prices and everybody would enjoy higher energy density, but they are most likely an either/ or issue as opposed to both. I'm looking for some expert knowledge and guidance as to how to select the best cell. All of my battery packs will include a battery manager. I have invested in a battery strip spot welding machine to rebuild or manufacture my own battery packs
