![]() ![]() We can typically work with you on pricing and availability for larger orders, too. Chances are, we have them in stock, it’s just not reflected on the website yet. 1 x Folomov 18650s Nichia 219D 15Modes 900Lumens LED Flashlight 1 x Micro USB rechargeable 18650 (2600mAh) 3.7V Li-ion 2 x spare o-ring 1 x Clip 1 x Lanyard. If you’re looking for cells, reach out to us and ask. Doing this improves battery life and increases the battery range substantially. These cells are named for their diameter and length, as they are 18mm wide and 65mm tall. Remember, some laptops use lithium polymer pouches, but if a laptop doesn’t, then the cells inside are going to be 18650s. Four additional batteries can be added by adding a quad expansion pack. If the laptop battery pack you are tearing down uses cylindrical cells, those are going to be 18650s. The consequences of this research will be massive. The GX2/4 is a box mod made by Smok that is powered by twin 18650 replaceable batteries that power the mod up to 220 watts. In fact, the National Science Foundation have invited us to submit a grant proposal to create a more in-depth means of analyzing cells for Second Life use and correlate as-received condition with remaining cycle life. We’ve analyzed dozens of thousands of 18650 cells totaling more than 100 kWh of actual capacity, and we’ve been able to reuse nearly two-thirds of them. Our new analyzers do this automatically, then spit the data into a database so we can assign them a grade based on performance characteristics as compared to their as-new specs. ![]() We’re always improving our grading methodology to better understand actual remaining life, so we've added an internal resistance test in addition to capacity. Finally, we’ve changed the way we grade cells.
