Yellow battery LED (Battery1 or Battery2 LED) blinking with long blinks
Faulty battery
The device has detected a short-circuit on the connected battery or that it has completely exhausted its capacity.
The device isolates the faulty battery and flags it with long, slow blinks on the matching LED, on the BDS180 unit and also on the MC-180 control panel. Turn the device off and back on to reset it manually.
DIY Safe
Yellow battery LED (Battery1 or Battery2 LED) blinking with short blinks
Battery protection function activated
The battery voltage dropped below 9.5V.
The battery protection function disconnects every user once the voltage falls below 9.5V, to prevent irreversible damage. If it stays below that threshold, power is only guaranteed for another minute, and if it drops as far as 8.5V the device shuts itself off entirely. Turn it off and back on again to reset it manually.
