The battery packaging is exquisite, and the shipment was dispatched promptly and delivered smoothly. I previously purchased 18650 batteries, which performed quite well. This time I tried buying 21700 batteries, and they feel great.
These are excellent high quality batterys, and the shipping was very quick.
I also use there VX4 V2 charger for piece of mind that these LiPo batterys are charged safely and in the correct manner.
Expect to get years of dependable service from XSTAR products!
Thank you….
