Victron BMV‑712 500 A smart battery monitor with inbuilt Bluetooth for precise state‑of‑charge, current and voltage monitoring on 12 V/24 V/48 V systems.

• Battery voltage: displays main battery/bank voltage and optional auxiliary battery via the auxiliary input (input voltage range: 6.5–70 V).
• Battery midpoint voltage monitoring: monitors multi‑battery banks, shows top and bottom section voltages and triggers an alarm if midpoint deviates.
• State of charge: indicated 0–100% (resolution 0.1%); Time‑to‑go: estimates remaining run time; Amp‑hours consumed: example – 12 A for 3h = 36 Ah consumed (amp hours resolution 0.1 Ah).
• Charging / discharging current and power: shows current (A) and power (W) flowing in/out; display resolution current 0.01 A, voltage 0.01 V; input current range (with supplied shunt) −500 A to +500 A; current and power shown as positive values when discharging.
• Battery temperature: optional Victron temperature sensor (ASS000100000) can be connected for temperature monitoring and alarms if outside safe range.
• Connectivity & relay: inbuilt Bluetooth for real‑time monitoring and programming via VictronConnect; bistable relay: 60 V / 1 A.
• System specifications: nominal battery voltage 12 V / 24 V / 48 V; supply voltage range 6.5–70 V; supply current 1 mA (12 V) / 0.8 mA (24 V); current draw (backlight off) <1 mA; operating temperature −20°C to +50°C; accuracy (with 500 A shunt) voltage ±0.3%, current ±0.4%.
• Dimensions & items supplied: LCD monitor front diameter 63 mm, depth 31 mm, square frame 69 x 69 mm, LCD weight 70 g; shunt 120 x 25 x 50 mm, weight 315 g. Standards: EN 60335‑1, EN 55014‑1/2, ECE R10‑4 / EN 50498. Supplied: 10 m connection cable, 2 m positive supply cable, 4 x mounting screws. 5‑year manufacturer warranty; note: shunt must be connected on the negative battery wire close to the battery.

Compatible with VictronConnect via Bluetooth; fits 12/24/48 V systems and can be expanded with Victron accessories for temperature sensing and system integration.
