About LOSSIGY

LOSSIGY is a battery monitoring app that connects to LOSSIGY LiFePO4 batteries via Bluetooth 5.0.
LOSSIGY helps users who need quick, nearby checks on battery status during trips, installs, and routine maintenance. It connects directly to the built in battery management system within about ten meters, so you can view key information from your phone while standing near the system. It is made for LOSSIGY 12 V, 24 V, and 48 V LiFePO4 packs that include a Bluetooth BMS used in RVs, golf carts, small solar setups, and trolling motors. For convenience, the LOSSIGY APK limits connections to one device at a time.
LOSSIGY features
Real time dashboard
LOSSIGY provides a live overview of battery state of charge, status, voltage, current, remaining capacity, temperature, cycle count, and overall health. You can glance at the screen to confirm conditions during charging, discharging, and storage. This helps you check how the pack behaves under load or while resting without extra tools.
Simple device management
The Device page lists nearby connectable packs so you can pick the correct battery before you start. You connect to a single pack at a time, which keeps readings clear and avoids mixed data. When work is finished, you can disconnect from the same page and move to the next pack.
On site control toggles
From the Control page, you can toggle charge, discharge, and auto balance settings when on site. This is useful when you need to pause output during wiring checks or enable balancing after an install. The app applies changes over Bluetooth, so you make adjustments without opening the battery case.
Deep parameters for diagnostics
View BMS protection thresholds for voltage, current, and temperature.
Confirm values set for charge and discharge limits before first use.
Use the data to guide basic troubleshooting and avoid guesswork.
Direct BMS data with Bluetooth 5.0
LOSSIGY apk reads straight from the battery’s BMS for low latency updates and accurate values. The short range is suited for nearby checks in the field, such as inside an RV bay or next to a golf cart. This approach reduces delays and helps users spot changes in current and temperature as they happen.
Supported batteries for LOSSIGY
This app is designed for LOSSIGY LiFePO4 batteries that include a built in Bluetooth BMS. Common setups include 12 V, 24 V, and 48 V packs used in RV power systems, golf carts, small solar banks, and trolling motors. If a pack does not have a Bluetooth BMS or uses a third party BMS, it will not appear in the Device list. Check your battery label or manual to confirm Bluetooth BMS support before pairing.
Bluetooth behavior and connection expectations
Bluetooth range is about ten meters in open space. Walls, metal compartments, or vehicle frames can reduce range. LOSSIGY connects to one device at a time to keep data consistent. Some users may notice that a pack appears connectable even when the main switch is off. In some cases, the BMS can continue to advertise over Bluetooth while protection is active. To reduce unnecessary connections, close the app after checks, turn off phone Bluetooth when not in use, or move the phone out of range.
Quick troubleshooting with the LOSSIGY app
If a battery will not hold charge, remove all loads and chargers, then test voltage with a multimeter before pairing.
If the pack seems unresponsive, briefly apply a compatible charge to wake the BMS, then try connecting again.
When pairing fails, ensure your phone’s Bluetooth is on and location permissions are granted for scanning.
If values seem unusual, verify terminals are tight and polarity is correct before running another test.
When multiple packs are nearby, connect to only one device at a time to prevent switching during a session.
For high load checks, watch current and temperature on the dashboard and stop the test if values approach limits.
How to use LOSSIGY on Android
Use the Lossigy app for quick checks and basic adjustments while you are near the battery. To begin, download LOSSIGY and confirm your phone’s Bluetooth is ready. Then follow these steps in order during an install or routine check.
Power your battery and make sure you are within about ten meters, then open the app on your phone.
Go to the Device page and select the correct pack from the nearby list to establish a single connection.
Open the dashboard to view state of charge, voltage, current, temperature, and other live readings.
If needed, use the Control page to toggle charge, discharge, or auto balance based on your task.
Check the Parameter page to review protection thresholds, confirm settings, and then disconnect when finished.
Start monitoring your battery
LOSSIGY apk gives on site access to live status, basic controls, and key parameters from the battery’s BMS. It suits RV, golf cart, solar, and marine users who need short range checks. To stay current, consider the LOSSIGY latest version when installing on a new phone or after a major system change.
