Live BMS puts every one of your lithium batteries on a single, beautiful dashboard — no more switching between manufacturer apps. Connect over Bluetooth to your LiFePO4 packs and watch what actually matters, live: state of charge, pack voltage, current, per-cell voltages, temperature, cycle count, and health. A liquid-fill charge ring and clear in/out power flow make each battery readable at a glance, and a running estimate tells you how long until the pack is full while charging or empty while it's under load. Built for people running more than one battery — on a boat, an RV, a van, or an off-grid solar setup. WATCH FROM ANYWHERE (OPTIONAL) Add the Live BMS Link, a small Wi-Fi bridge that sits with your batteries, and your dashboard keeps updating when you're nowhere near the boat. Without it, Live BMS works exactly as it always has — Bluetooth only, nothing leaves your phone. FEATURES • One dashboard for all your batteries, updating in real time • Auto-detects supported BMS units — no fiddling with settings • Live "time to full" and "time to empty" at the current rate • Battery banks: group the packs wired together and see one combined charge, power draw, and runtime • Trip tracking: compare where you started to now, burn rate, and days remaining at your current use • Per-cell voltage bars and imbalance so you can spot a weak cell • History charts for charge, voltage, and current • Remote output on/off, including a master switch for all batteries • Alerts for low charge, high temperature, and cell imbalance — with plain-language guidance on what to set • Optional Live BMS Link accessory for checking your batteries from anywhere • Fahrenheit or Celsius, and Light / Dark / System themes FREE VS PRO The free version shows live charge and voltage for one battery — so you can prove it works with your hardware before paying anything. A single $4.99 unlock adds everything else: full telemetry, trips, history, alerts, power control, banks, and unlimited batteries. SUPPORTED BATTERIES Works with LiTime, Power Queen, and Redodo LiFePO4 batteries, plus common JBD / Xiaoxiang, JK-BMS, and Daly BMS units. More families are being added. PRIVACY Live BMS has no accounts, no ads, and no analytics. It talks directly to your batteries over Bluetooth and stores your history on your phone. If you add the optional Live BMS Link, your own battery readings pass through our server so you can see them remotely — nothing else does, and none of it is tied to your name, your email, or anything that identifies you. Note: Live BMS is an independent app and is not affiliated with or endorsed by LiTime, Power Queen, Redodo, or any BMS manufacturer.
