SmartBMS Pro–LithiumBatteryBMS

🔋 SmartBMS Pro turns your phone into a precision battery monitor for JBD, Xiaoxiang, Overkill Solar and Grenergy-compatible smart BMS units. Connect over Bluetooth and see exactly what your lithium pack is doing — every cell, in real time.

Whether you run a LiFePO4 house bank in a camper van, a solar storage wall, an e-bike, or a marine battery, SmartBMS Pro gives you the live data and safety controls the built-in BMS was hiding.

📊 LIVE DASHBOARD
• State of charge, pack voltage, current and power at a glance
• Two temperature sensors, cycle count, remaining and full capacity
• Clean, high-contrast dark instrument UI that's easy to read in the field

🔬 PER-CELL DETAIL
• Every cell voltage with healthy / low / critical colouring
• Min, max and delta so you can spot an unbalanced cell instantly
• Live balancing indicators

🔌 MOS CONTROL
• Switch the charge and discharge MOSFETs on or off from your phone
• Every switch is behind a confirmation so it never happens by accident

🚨 ALARMS & PROTECTION LOG
• Notifications and in-app banners for protection trips, low charge and high temperature
• A timestamped protection event history you can export to CSV
• Configurable low-SOC and high-temperature thresholds

⚙️ BMS PARAMETER CONFIGURATION
• Read and write EEPROM protection settings: cell and pack voltage, current and temperature limits, capacity and balancer
• Every write is range-checked, confirmed twice, and verified by reading the value back
• Back up and restore your configuration

📡 BUILT TO STAY CONNECTED
• Automatic reconnect after the normal Bluetooth drops of real-world use
• Background monitoring keeps alarms working when the app is off screen
• Monitor up to four batteries at once and swipe between them

📈 HISTORY
• State-of-charge and voltage charts
• Charge and discharge session history with CSV export

✨ PREMIUM (OPTIONAL)

✅ COMPATIBILITY
Works with JBD / Xiaoxiang / Overkill Solar / Grenergy smart BMS units that expose the standard FF00 Bluetooth service (common on 4S–16S LiFePO4, Li-ion and lead-acid replacement packs). A Bluetooth-enabled BMS is required.

🔒 Bluetooth permission is used only to find and talk to your BMS — no location is tracked. SmartBMS Pro is an independent app and is not affiliated with any BMS manufacturer.
