I appreciate all the various product options that your website offers. If your website had an option to sort your database via other criteria, like size or weight, that would be very useful. Digikey is a good example of being able to apply many different filters to the database to see what product options are available.
use higher end lithium cells

The website was very educational and assisted in my decision of which battery pack to purchase. I see that they use higher end lithium cells. I also purchased the matching recommended charger which is also working just fine. I would use this company again whenever I need to research and purchase any power needs in the future. I design medical and innovative products most of which have a power requirement. The new lithium technology is the future in both power and size requirements. Thanks for all your assistance.
