Unreliable product, poor customer service
Bought a 230ah 12v battery, shipped fast and seemed fine upon delivery, but BMS randomly disconnects for short periods. This happens regardless of battery state of charge, charging or discharging rate, or temperature. Product is useless. Tech support unable to help, no response for almost 2 weeks then started asking questions trying to blame my installation for the issue. I tested with just a digital clock connected, battery cannot power even a simple low power device reliably. Avoid this product and avoid this company.
