This 18350 is a great choice for a high capacity and high discharge rate small sized battery. It is PCB protected button/nipple top.
This cell compares to the 1200mAh cell some of our competitors are selling and is the same cell in the top grade, but 1200mAh is an exaggerated rating so we rate ours more realistically.
Please note as with all protected batteries the protection circuit adds a few millimeters of length so it is slightly longer than an unprotected 18350.
These are manufactured in an ISO 9001 facility with a very high quality PCBA including a Japanese Ricoh protection IC with three FNK MOSFETs for 20A high current cutoff (most PCBs will not be able to handle this much current). This protection circuit protects the battery from mishandling, overcharge, or overdischarge while allowing the battery to do its job properly.
These batteries have a UN38.3 / DOT test report available and are legal for shipping. Many protected batteries on the market actually do not have any test data and are likely illegal for shipping due to lack of UN38.3 test report. Many competitors don't realize that a separate test needs to be done on the battery assembly and that the cell test is not enough. All of our batteries include a UN38.3 report available upon request.
