<br>
Based on glowing reports from the RE list, I finally used Fortress for a <br>
battery replacement for a long time customer. Overall, it seems to be a <br>
better solution than others I've seen. However, we are having issues. <br>
First the two batteries are supposed to be linked together in a master/ <br>
slave configuration, but they charge and discharge unevenly, and have <br>
SOC often 20% different. Batteries are connected to a common buss with <br>
equal length 4/0 cables.<br>
<br>
I've been truly disappointed with Fortress customer support. First, I've <br>
called multiple times over the past two weeks, and never got through to <br>
anyone. Their online support system is quite flawed as well, and I had <br>
a very difficult time even setting up a support ticket. Now I can't <br>
even log in to view the support ticket, and I've only received one email <br>
back asking if I had properly paralleled the batteries.<br>
<br>
Has anyone else had a hard time with Fortress support? Does anyone have <br>
a direct contact? Customer is beyond pissed now, after almost 2 weeks <br>
hearing nothing, and having spent tens of thousands.<br>
<br>
Thanks;<br>
