Great product and service
After I received my 2 300Ah LiPo batteries, I managed to accidentally short circuit one of them. The battery still worked, but the BMS didn't show the correct voltage compared to the measurements I did using a voltmeter. I got in touch with customer support at Vatrer to help me diagnose the state of the battery. Jovie at Vatrer helped me and concluded that the battery was damaged. Jovie started immediately the process of replacing the battery on warranty. So within a week I received a new battery on warranty. The prompt and positive response from Jovie at Vatrer confirmed the already positive impression I had gained of the company before I initially ordered the batteries. In short, service is excellent and shipping is fast. They stand by their warranty.
