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!

I have been using these batteries for personal medical and other support as well as backups for community safety equipment that runs when power fails. Many years of use, dozens in the field, and NO failures EVER. Absolute first choice for any need. Tom

These Lifepro4 batteries are used in my emergency back-up power system, and I expect to get 15 to 20 years of life out of them. LifePro4 batteries are expensive, but they will last a long time if you follow the steps to prep them and use a Battery management system (BMS) available on Amazon. Lithium-based batteries aren't coming down in price anytime soon.

Just bought and tested these. As far as longevity... thats yet to be seen. But ah rating? More than advertised!!!

As expected, fast shipping, will order more
