BMS Monitor & Config

Free & unlimited for BAKOM.CZ batteries. Other JK BMS packs: 30-day free trial, then a one-time lifetime unlock — no subscription.

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.
