Bluetooth Smart LiFePO4 Batteries

Every SOK LiFePO4 battery ships with a built-in Bluetooth-enabled BMS (battery management system) and the SOK Battery smartphone app for iOS and Android. That means real-time monitoring of state of charge, individual cell voltages, internal temperature, charge/discharge current, total cycles, and remaining capacity — without buying a separate shunt monitor or hardwiring a display.

Who This Is For

DIY solar builders who want diagnostic-grade visibility, RV and van owners who want to check battery status from inside the house, off-grid cabin owners checking on remote systems, anyone replacing 'dumb' AGM banks with smart lithium for the first time.

Key Specs to Look For

• Bluetooth Low Energy — works with any iOS or Android device within ~30 feet
• SOK Battery app (free download) — single app monitors multiple SOK batteries simultaneously
• Real-time metrics: SOC %, voltage per cell, temperature, current in/out, cumulative cycles
• Historical logging — track battery health over months/years
• Firmware updates (select models) — improvements pushed over-the-air via app

Why Choose SOK LiFePO4

Lead-acid batteries are black boxes — you measure voltage with a multimeter and guess at state of charge. SOK's Bluetooth BMS turns the battery into a queryable, observable system: you know exactly what's happening at the cell level, can spot a weak cell before it kills the bank, and can verify your charge controller is hitting actual cell targets rather than guessing from voltage curves.

Frequently Asked Questions

Do I need a Wi-Fi connection?
No — Bluetooth is direct device-to-battery. You don't need internet or a hub. Just install the SOK app on your phone.

How far can I be from the battery?
Typical Bluetooth range is 30-50 feet line of sight. Through walls or metal RV compartments, range may drop to 15-25 feet.

Can I monitor multiple SOK batteries from one app?
Yes — the SOK app supports multiple batteries simultaneously. You'll see each as a separate device with its own SOC and metrics.
