Charge it to activate. If the cells are charged already, discharge and try again. The App is available at Google Play. Has a green Diamond that says BMS on the logo
In the Smart Series you can adjust these parameters with Bluetooth App or with the PC connection. Possible that you can do it on the touchscreen display too, but I can't confirm that.
I am looking for someone to parse the DALY or HEYO Smart BMS data (I have identified it and have all of the addresses etc...) and make it display on a Intelligent LCD like Nextion or??? It is for a product I manufacture and I will pay appropriate rates to get it done right. Interested...
