I have ordered over 300 cells with expertpower us and they have been great! The come with all the bus bars, terminal screws and plastic protectors which is a huge help! They are extremely professional, the products ship same day and I could not be more happy with them! We build batteries for golf carts and we have made well over 20 - 16 cell batteries! My oldest one is probably 2.5 years old and is used every day. They still work like the first day I got them! I would highly recommend them to everyone!
