    Great Battery

    Posted by Jacek M Kucy on Oct 15th 2020

    I built quite a few batteries using these cells. Great quality. They perform very well. They come from this store with about 8% of the charge, consistently. No differences in voltage. I am very satisfied with my multiple purchases.

    Awesome batteries.

    Posted by Vincent Adeva on Jul 18th 2020

    My application is 72 volts for eBike. These batteries can make you fly! Love it and they're relatively low priced. This site is my only Samsung store. Shipping is also great and fast, let alone I'm on the west coast.

    Thank you, hope your price won't change.
