Purchased 2 320 Ah batteries
Purchased 2 320 Ah batteries. One had BMS issues within 3 days of installation. It was reporting inaccurate telemetry. By the end of the first week of it being installed, it no longer contributed any power to the load demand. Contacted support via their 800 number. Customer support continually recommended that I do things in which I had already started I did before calling. The customer service was useless and offered zero resolution. I contacted customer service through their email. It takes 24 hrs at a minimum for them to respond. When you are using their batteries for off-grid use and your power needs completely hinge on the batteries functioning properly, this is not the customer service you would like. They took nearly one week to approve a warranty claim on a battery purchased 2 weeks earlier. Then they told me to box it and ship it and that I’d be liable for any damages. I asked them to send the replacement battery and I would use that battery’s form fitted box to send them the failed battery. They said that is a good idea and they will take it into consideration but for now send them the battery. That’s not taking it into consideration. They are difficult to work with. I wouldn’t recommend.
