BMS Monitoring Suite for iPhone + iPad

Your batteries. One clear view.

Name: BMS Monitoring Suite
Availability: InStock

Monitor compatible Bluetooth batteries, battery banks, and power systems from one read-only dashboard. Move from live system totals and estimated runtime to individual battery readings, cell voltages, history, and optional Power Map locations.

Explore realistic sample systems in Demo Mode before connecting hardware. BMS Monitoring Suite does not expose controls for changing device settings.

BMS Monitoring Suite Demo Mode dashboard showing two sample battery systems with charge, voltage, current, power, temperature, signal strength, and estimated runtime

From bank overview to cell detail

Actual app screens

See the complete system first, then open the readings that matter. Available telemetry depends on the connected hardware.

BMS Monitoring Suite system summary showing charge, voltage, current, power, temperature, estimated runtime, capacity, energy capacity, and a historical chart — Know the state of the whole bank

See aggregate charge, voltage, current, power, temperature, capacity, energy, and a load-dependent runtime or charging estimate where the hardware reports enough data.

BMS Monitoring Suite Power Map showing three sample battery-system locations with controls to start mapping and center the map — Put nearby systems on the map

Use optional Power Map to estimate and confirm where systems are located from foreground location and Bluetooth signal observations.

BMS Monitoring Suite battery detail showing live telemetry, health, cycle count, lifetime discharge, and four individual cell voltages — Look inside each battery

Inspect individual charge, voltage, current, power, temperature, capacity, health, cycle count, and cell voltages when the device provides them.

BMS Monitoring Suite historical data view showing a 24-hour state-of-charge chart for two sample batteries and a CSV download button — Review and export history

Explore trends from 15 minutes to 24 hours, switch among available measurements, zoom and pan, then export recorded readings as CSV. Logging runs only while the app is active in the foreground.

Built for the work before the readings

Clearer setup

Find, identify, and verify

Start with Add device, choose the brand, model, or manufacturer app you recognize, then scan nearby. The setup flow checks for fresh telemetry before treating the connection as verified.

Build the bank you actually have

Start with one battery, then expand the system into a series or parallel bank. BMS Monitoring Suite keeps system totals and each battery's readings close together.

Explore before pairing

Demo Mode shows realistic live telemetry, runtime estimates, history, battery detail, and individual cell readings without starting Bluetooth or changing saved configuration.

Keep configuration private

No Oontz account is required. Optional configuration sync uses your private iCloud account; live telemetry, local history, and Power Map data are not synchronized through CloudKit.

Compatible battery and power-system families

Local Bluetooth

Compatibility and telemetry completeness vary by exact model, internal BMS supplier, and firmware. Experimental support verifies what a specific nearby device actually returns instead of assuming compatibility from a brand name alone.

Standard support

LiTime batteries with built-in Bluetooth
Daly BMS devices and batteries documented for the SMART BMS app
Supported EcoFlow power stations using local Bluetooth

Experimental batteries + BMS

Redodo, Power Queen, JBD / Jiabaida / Xiaoxiang, and Overkill Solar-compatible systems
Renogy batteries, JK / Jikong, CHINS / E&J, SOK / ABC BMS, WattCycle / TDT, and HumsiENK-compatible batteries
EG4 LL / Sungold, Pylontech RT-series, and ANT smart BMS units

Experimental power systems

Victron devices with encrypted, receive-only Instant Readout telemetry
Anker SOLIX, BLUETTI, Renogy BT-1 / BT-2, and first-generation Zendure SolarFlow
Lithionics, Pro BMS, Vatrer, RoyPow, and Seplos

Battery monitoring guides

Setup + troubleshooting

Connect compatible hardware, understand a multi-battery layout, and work through common Bluetooth discovery problems.

Monitor Bluetooth batteries

Prepare the hardware, add a nearby device, verify fresh readings, and save a useful dashboard.

Read setup guide

Battery not found?

Work through the most common causes of missing, sleeping, busy, or incorrectly identified Bluetooth batteries.

Troubleshoot a connection

Series vs. parallel

Understand how battery-bank wiring affects voltage, capacity, current, and the totals shown in a monitoring dashboard.

Compare configurations

Good to know before connecting

Honest limits

One Bluetooth client at a time

Discover devices inside BMS Monitoring Suite, not in the Bluetooth page of Settings. Fully close manufacturer apps on nearby phones and tablets because most battery devices accept only one active client.

History is foreground-only

Historical logging is optional and records only while the app is active in the foreground. It is not continuous background or remote monitoring.

Runtime changes with the load

Time remaining is an estimate based on available telemetry and recent conditions. It can change as the load, charging input, battery state, or hardware reporting changes.

Monitoring is not protection

BMS Monitoring Suite is a read-only monitoring aid. It does not replace the battery's protection system, electrical safeguards, manufacturer guidance, or professional diagnosis.

Private by design

No ads or tracking

BMS Monitoring Suite includes no advertising, developer-operated analytics, or third-party tracking. Battery telemetry and optional Power Map data stay local, while configuration can sync through your private iCloud account.
