Mr Ray Armstrong

The EG4LLS batteries have arrived. We just had the County final inspection. One of the prior EGG4'S didn't come on so we used on of the new ones. Our permit was for 4 batteries, so we used one of the new ones. I need a replacement on the battery that didn't come on. I want to install all 6 batteries which is 50% overkill.

Let me know and I will send you the serial number.

Excellent Battery!

There is really nothing to complain about other than the price increase from the tariffs! I have an entire cabinet of these batteries and they perform flawlessly. The US EG4 support is also top notch! Buy it and don't look back. There are cheaper options out there, but good luck if you have a problem.
