Everything the OEM app forgot.

Built for off-grid setups, vanlife rigs, photographers, and anyone who actually needs to see what their pack is doing in real time.

One-tap BLE pairing

Scan, connect, and auto-reconnect to LP1, LP2, and LP+ devices.

Live telemetry

Battery level, capacity, voltage, current, and remaining runtime — streamed live.

DC port control

Toggle output, monitor power, and flip on bypass mode when you need direct passthrough.

USB-C insight

Charging vs discharging state, port temperature, live power readings.

Power limits

Set global, input, output, and runtime caps from 30W to 100W.

Smart scheduling

Up to 6 timers — one-shot, daily, weekly, or monthly — for hands-free DC cycling.

Date & time sync

Push your phone's clock to the device in a single tap.

Expert & Dev modes

Restart, shut down, factory mode, BLE PIN — all the controls, none of the menus.
