About this app

Live monitoring for your NZ Lithium battery, straight from your phone.
The NZ Lithium app is built specifically for the LiFePO4 batteries we hand-assemble in Motueka. We use the same batteries off-grid at home - we wanted a monitor that actually works the way our customers need it to.
Connect over Bluetooth and you see exactly what your battery is doing in real time: state of charge, voltage, current, temperature, and every cell voltage. If something goes wrong, you get a clear, plain-English description of the protection event — no obscure codes to look up.

WHAT YOU GET
• Live battery state — SOC, voltage, current, temperature, every cell voltage from 12v right through to 48v packs
• System log - every protection event, charge cycle and alert.
• Home screen widget - see your SOC at a glance without opening the app (while in range)
• Auto-reconnect - Your choice to stay connected in the background so you don't miss anything (while in range)
• Diagnostic export — share a snapshot of your battery state with your installer (or with us, if you'd like a hand)
• Built-in bug report — message us straight from inside the app

WORKS WITH VICTRON ENERGY GEAR
If you've got a Victron SmartShunt, SmartSolar charge controller or other Victron Bluetooth device on the same system, the app reads it alongside your NZ Lithium battery so you see the whole setup in one place.

YOUR DATA STAYS YOURS
There are no accounts, no sign-ins, no ads, no analytics, no tracking. The app does not send any information to NZ Lithium or to anyone else automatically. Bluetooth data flows directly between your phone and your battery — no cloud in the middle. The only time anything leaves your phone is if you choose to send us a bug report or share a diagnostic export, and both are completely opt-in.

BUILT FOR OFF-GRID, MOBILE AND MARINE
Whether you're running a tiny home, a caravan or camper, a bach in the Marlborough Sounds, a boat, a 4WD setup, a workshop ute or a golf cart — if you're running NZ Lithium batteries, this app is for you.

ABOUT NZ LITHIUM
We're a small team in Motueka who design, hand-build and hand-test LiFePO4 battery packs for off-grid, marine, caravan and lifestyle use across New Zealand. We use the same batteries to power our own homes. Every battery is assembled by hand and tested for capacity, load and irregularities before it ships.
