Ghosted when asking for support
I'm an electrical engineer. Had issues with voltage drops when under load. Requested help and they recommended I remove the load to test it. Replied, that makes no sense, since the problem only manifested under load, and they ghosted me. I (without their help) have since corrected what seems to be a BMS problem. With the exception of the BMS, product quality seems good, but don't expect them to honour warranty or to give tech support.
