Description
BatteryScope is a Bluetooth dashboard for lithium batteries with a built-in battery management system. Whether you have one LiFePO4 pack in your van or several wired in series and parallel on a boat,
BatteryScope shows you the live numbers that matter — voltage, current, state of charge, cells, temperatures, and cycles — for every pack in your rig, in one place.
LIVE READINGS
• State of charge with time-to-empty and time-to-full estimates
• Pack voltage and current, plus instantaneous power draw
• Cell-by-cell voltages with min, max, delta, and balance health indicator
• Multiple temperature sensors per pack
• Charge and discharge MOSFET status
• Total cycle count
GROUP BATTERIES THE WAY THEY'RE WIRED
If your batteries are wired in series for higher voltage or in parallel for more capacity, BatteryScope reflects that. Create groups, name them ("House Bank," "Bow Thruster," "Solar Array"), and see correctly
aggregated stats:
• Series groups: voltages sum, weakest cell governs SOC
• Parallel groups: capacities and currents sum, voltages average
• Drill into any single battery to inspect cells, temperatures, and device info
NO ACCOUNT, NO CLOUD, NO TRACKING
BatteryScope stores everything locally on your device. No signup. No telemetry. No analytics. No data ever leaves your iPhone. Bluetooth is used solely to talk to your BMS.
COMPATIBLE WITH JBD-PROTOCOL BMSES
BatteryScope speaks the JBD / Xiaoxiang BMS protocol, the de-facto standard inside most consumer-grade Bluetooth-enabled lithium batteries. If your pack has Bluetooth and a JBD-compatible BMS, BatteryScope can
read it. Tested with packs from Impulse Lithium, with broad compatibility for other vendors that use the same protocol.
Not sure if your pack is compatible? Open the Scan tab — any nearby BMS advertising itself as "BMS," "LiFePO4," or the FF00 service will show up.
DESIGNED FOR REAL USE
• Failed connections offer one-tap retry directly from the dashboard
• Built-in diagnostics show exactly what your BMS is reporting
• Optional developer mode logs every Bluetooth event for troubleshooting
• Cell-balance indicator (Δ, color-coded green / orange / red) catches drift early
• Supports portrait and landscape on iPhone and iPad
WHO IT'S FOR
• Boat, RV or van owners running 12V, 24V, or 36v lithium banks
• Off-grid solar setups and shed builds
• EV converters and DIY lithium pack builders
• Anyone tired of pack-vendor apps that only show their own brand
PRIVACY
BatteryScope does not collect, transmit, or share any personal data. All battery configuration is stored locally on your device. Bluetooth is used exclusively to read live data from your BMS.
