About this app

BAKOM BMS monitors lithium (LiFePO4) batteries with a JK BMS over Bluetooth — and your whole energy system. Battery, inverter, solar charger and DC-DC converters together on one screen.

ASSEMBLIES — YOUR WHOLE INSTALLATION IN ONE PLACE
• Combine batteries, a BAKOM Bridge and Victron devices into one assembly, such as “camper” or “cabin”
• Shared overview: state of charge of the whole bank, total power and current, status of every device
• On launch the app connects to the assembly and opens it right away
• For every device you can see at a glance whether it is connected and whether data is coming in

JK BMS BATTERIES
• State of charge, voltage, current, power and temperatures (including MOSFET temperature)
• Live voltage of every cell, difference between lowest and highest, balancing, internal resistance
• Capacity, remaining energy, cycle count, runtime estimate and time to full charge
• Expert mode: charge and discharge MOSFET, heating, calibration
• Diagnostics and export of measured data

VICTRON ENERGY DEVICES (read directly over Bluetooth)
• MultiPlus and Quattro inverters
• SmartSolar MPPT solar chargers
• Orion Smart and Orion XS DC-DC converters
• SmartShunt and BMV chargers and battery monitors (coming soon)

BAKOM BRIDGE (optional hardware)
• The BAKOM Bridge module sends battery data over WiFi, beyond the reach of your phone’s Bluetooth
• Expert mode works over the bridge too

DESIGNED FOR READABILITY
• Large numbers, calm colours, no needless flashing
• Works with enlarged system font — a value is never cut off
• Light and dark appearance, phone and tablet
• Runs on older devices too — Android 6.0 and newer
• Czech, Slovak and English

ACCESS
BAKOM batteries are always unrestricted in the app — whether you watch them over Bluetooth or through the BAKOM Bridge. For other batteries with a JK BMS and for Victron devices you get 30 days to try everything out; after that a one-time purchase unlocks full access. No subscription.

SUPPORTED BMS
Jikong (JK) BMS series B and PB, JK02 protocol, firmware 19.x — for example B2A8S20P or PB2A16S20P.

PRIVACY
No ads, no third-party tracking. Battery telemetry is shared only with BAKOM’s own service, for registration and diagnostics.

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

What’s new

Battery registration fix: on smaller screens the keyboard covered the submit button and the form could not be completed.
