Battery monitoring for your phone.
EasyBMS connects straight to your Bluetooth BMS — real-time cell monitoring, fault alerts with push notifications, MOSFET charge and discharge control, and APRS telemetry, all from your pocket.
EasyBMS is a battery management companion for Android that connects directly to your Bluetooth BMS devices. It supports Daly, JBD/XiaoXiang, and other popular Bluetooth battery management systems. Get real-time cell monitoring, fault alerts with push notifications, MOSFET charge and discharge control, and APRS telemetry — all from your phone.
Everything your pack is doing, in real time
From cell-level voltages to remote MOSFET control, EasyBMS puts a full instrument panel in your hand.
BLE Discovery
Scan for Daly, JBD, and other Bluetooth BMS devices in range and add them to your dashboard in seconds.
Cell Monitoring
Individual cell voltages displayed in real time with configurable imbalance detection and visual alerts.
Fault Detection
OVP, UVP, OCP, and OTP fault monitoring with instant push notifications to your device.
MOSFET Control
Toggle charge and discharge MOSFETs on or off directly from the app for safe battery management.
Supervisory Control
Layer your own protection rules on top of the BMS — alert on voltage, current, SOC, or temperature thresholds you define.
APRS Telemetry
Beacon battery voltage, current, SOC, and temperature to the APRS-IS network automatically.
Remote Monitoring
TCP server connectivity lets you monitor BMS data remotely from anywhere on your network.
SOC Calibration
Reset state of charge to 100% when your pack is fully charged for accurate capacity tracking.
Multi-Device
Monitor up to 7 devices with an Android phone, or scale onward with EasyBridge and the EasyBMS Server.
Pick the plan that fits your fleet
Start free on a single battery, unlock the full instrument panel with Pro and Platinum, or hand it all off to a managed EasyBMS Server.

1 A valid Amateur Radio license is required for reporting to APRS-IS.
2 Not all batteries allow changing protection settings. Use our Supervisory Control layer to implement your own protection settings in addition to the battery's built-in, immutable settings.
3 For batteries that support remote control commands (MOSFET switching, SOC reset).
4 SMS alerts are sent by the Android phone running the EasyBMS app, using its messaging plan.

| Your battery | Don't see your brand? Ask us — new drivers are added regularly | Future |
Supported — tested on at least one model from the brand and actively maintained; additional models developed on request.
Experimental — early driver built from protocol analysis and not yet hardware-verified on every model; may be read-only or incomplete. Enable experimental drivers in the app to try it.
Future — not yet supported, but on the roadmap — ask us and we'll evaluate it.
Scale past your phone
When one phone and seven devices isn't enough, EasyBridge and the EasyBMS Server carry your whole battery fleet.
EasyBMS Server
Fully Managed Cloud ServiceA dedicated server that brings every battery you own together in one place. It aggregates live telemetry from the phones and EasyBridge devices registered to your account, monitors around the clock, and scales well beyond the app's 7-device limit. The customer portal lets you pair and manage EasyBridge units, scan for and add new batteries, organize packs into physical or virtual parallel banks, and track bank state of charge with LiTime and Victron shunts. Your data stays yours: 180 days of telemetry history, flexible interactive graphs, automated battery health reports, and CSV downloads for your own processing. Fault alerts arrive the moment something trips, EasyBridge firmware updates are delivered over-the-air, and APRS-IS support allows ham radio operators to share their data on the APRS network. Fully managed and hosted for you — just pair your EasyBridges and go. Low cost hardware available with the Server subscription.
EasyBridge
Low-Power BLE-to-WiFi BridgeYour batteries live in the shed, the camper, the far corner of the property — you shouldn't have to. EasyBridge is a tiny, low-power bridge that parks next to your battery bank, picks up its Bluetooth telemetry, and streams it to your EasyBMS Server through an encrypted tunnel. Anywhere with WiFi coverage becomes Bluetooth range: sheds, RVs, trailers, remote enclosures. Pair it to your account once and it runs headless from then on, with firmware updates installed over-the-air — no trip out to the battery bank required. A display-equipped model shows live pack status right at the battery.
