I don't know about you but when looking for my 18650s I found Nkon's website to be a real pain in the arse to filter out which batteries were the best or which ones met my needs.
Because of this, I've created a little handy filtering tool on my website that lets you see all of their 18650 products and enables you to filter the results down to meet your criteria. You're viewing exactly the same results as on their site as it gets it's data live, but you're just able to filter it. Any clicks on the products will take you directly to their secure site.
You can also enter your pack specifications such as 8s4p, and it will give you a total cost (without bulk discount) for your whole pack in order to gauge roughly how much your pack will cost.
Hope this helps.... let me know what you guys think?
