With the rising cost and decline in availability of cells from some manufacturers, we have released this 3400mAh protected battery. It builds on the success of the Protected 2600mAh battery and offers a lower cost high capacity cell from the same cell manufacturer for those that want one of the best protected 18650 batteries around without having to pay too much for it. A GREAT VALUE CELL WITH MAXIMUM CAPACITY We utilize a cell from an up and coming Chinese factory. The cell is the Sinowatt SW18650-34MP. It is a 3400mAh 10A continuous cell. While some cells are rated as 3500mAh, their minimum is usually 3250 which is the same as this one. This cell therefore competes for the absolute most capacity you can get out of an 18650. It is fully certified to all safety standards. DESIGNED IN USA USING TOP QUALITY COMPONENTS These LiionWholesale Protected 3400mAh batteries are manufactured with the same protection circuit board that we put in our highest level protected 3500mAh batteries like the protected NCR18650GA and protected INR18650MJ1. It includes a very high quality PCB including a Japanese Ricoh protection IC with three 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. The cell is made in China. Our company then adds the high quality PCB along with the button top in an ISO:9001 certified factory to all safety standards. A black wrap is put over the top to hold it together. Quality control and design are done in the USA. UN38.3 SAFETY TESTING COMPLETED ON BOTH CELL AND ASSEMBLY Please note that these batteries have a UN38.3 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.
