Housed in an IPX7-rated enclosure with reverse‑connection protection, it can be mounted with the included bracket, double‑sided adhesive or screws. The unit stores your settings after power loss and lets you toggle between voltage and temperature readouts, plus configure high\/low buzzer thresholds for early warning.\u003c\/p\u003e\n\n\u003ch3\u003eHow accurate is the SUPNOVA monitor for different battery chemistries?\u003c\/h3\u003e\n\n\u003cp\u003eThe monitor reads actual pack voltage and converts that to a percentage capacity based on default 12V lead‑acid mapping; other chemistries are supported but require initial configuration. For best estimates, select the correct voltage range and battery type during setup and allow the monitor to learn real‑world usage patterns over several charge\/discharge cycles.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eVoltage range: 7–100V (covers 12V–84V systems)\u003c\/li\u003e\n  \u003cli\u003eWorks with lead‑acid, AGM, LiFePO4 and ternary lithium batteries\u003c\/li\u003e\n  \u003cli\u003eDefault calibration: 12V lead‑acid (user adjustment recommended)\u003c\/li\u003e\n  \u003cli\u003eDisplays percent capacity derived from measured voltage\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat protections and environmental ratings does it offer?\u003c\/h3\u003e\n\n\u003cp\u003eThe SUPNOVA monitor is IPX7 water‑resistant and built inside a fully enclosed shell to resist dust and splashes, suitable for both indoor and outdoor installations.
