Received my AC200P yesterday, based on all the online reviews and videos they showed a BMS voltage screen where you could see all the individual cell voltages. This was one of the main reasons I purchased the unit so I could monitor long term battery health.
My Data - BMS Maintenance screen does not show temperature and there is no next button with voltages. My concern is the smart BMS was replaced with a cheaper dumb BMS as a cost savings.
Does the unit protect the cells from low temperature charging? I don’t see how it can without a temp sensor.
I am tired of blackbox BMS units where you don’t know what is going on.
