## What is BMS Monitor & Config?

BMS Monitor & Config is a smart monitor and manager for lithium (LiFePO4) batteries with a JK BMS, over Bluetooth. Unlike most BMS apps, it can monitor SEVERAL BATTERIES AT ONCE and merge their data into one aggregated view — total power, current and state of charge of your whole bank on a single screen. Clear and fast, on iPhone and iPad.

FEATURES
• Multiple batteries at once — connect up to 4 packs and watch the whole bank in one aggregated view (combined power, current and charge) with quick switching between packs
• Live per-cell voltages + balancing status
• SOC, current, power, temperatures (incl. MOSFET), cell internal resistances
• Cycle count, capacity and remaining capacity
• Controls: charge and discharge MOSFET, heating, voltage and current calibration
• Diagnostics, event log, XLSX data export
• English, Czech, Slovak

WHO IT'S FOR
The app is FREE and unlimited for BAKOM.CZ batteries. For other JK BMS packs you get a 30-day free trial; after that a one-time lifetime purchase unlocks full access. No subscription, with Family Sharing.

SUPPORTED BMS
Jikong (JK) BMS B and PB series (JK02 protocol), FW 19.x — e.g. B2A8S20P, PB2A16S20P and others.

PRIVACY
No ads, no third-party tracking. Battery telemetry is shared only with BAKOM.CZ's own service (registration and diagnostics) — see our privacy policy.

BAKOM.CZ — Czech manufacturer of battery packs and energy-storage systems.
