Multi-protocol monitor for supported lithium battery management systems over Bluetooth. View voltage, current, SOC, temperatures, and cell-level data from supported hardware at a glance.
Packed with features designed for real-world battery monitoring.
Monitor multiple supported BMS packs from one dashboard. Ideal for RV, marine, solar, and equipment banks.
Recognizes supported BLE BMS devices from a scan and applies the matching parser when available.
Voltage, current, SOC, temperatures, cell voltages, and power — all updating live over Bluetooth.
Combine packs into parallel or series banks. View aggregated stats for your entire system.
4 display modes — grid, bars, horizontal bars, and heatmap. See cell balance at a glance.
Configurable low-voltage and high-temp warnings with haptic feedback. Never miss a critical event.
Rolling 5-minute sparkline charts for voltage, current, SOC, and temperature trends.
Background-aware monitoring keeps active sessions visible longer, with alert behavior depending on device OS limits.
Scan nearby Bluetooth BMS devices and connect when MultiBMS recognizes a supported protocol.
