2.4 Bluetooth LCD Monitor Connection
The wireless Bluetooth LCD Monitor is included. Connect its positive and negative terminals to the corresponding terminals of your golf cart's switch key. This allows you to monitor the battery status via Bluetooth. A reserved communication port on the battery is available for wired communication monitors, which must be purchased separately if desired.
3. Oibríocht
3.1 Monatóireacht Ceallraí
Monitor your battery status using two methods:
- Bluetooth LCD Monitor: Provides real-time data on battery capacity, voltage, and fault codes. Effective up to 49.2 feet away.
- APP Móibíleach: Connects via Bluetooth to your smartphone, displaying key battery information. Effective up to 32.8 feet away.
Nóta: Both the APP and LCD Monitor connect via Bluetooth and cannot be used online simultaneously.

4. Cothabháil agus Sábháilteacht
4.1 Gnéithe Sábháilteachta
The DC HOUSE lithium battery incorporates several safety features:
- Cás Miotail: The sturdy, fireproof, and anti-collision sheet metal case provides superior protection compared to ABS-cased batteries, especially against high-current fires if misused.
- Internal Fixtures: Metal fixtures secure Grade A internal cells, reducing the risk of swelling and extending lifespan.
- Cosaint BMS: The integrated Battery Management System (BMS) offers 6 key protections: overvoltage, undervoltage, overcurrent, short circuit, high temperature, and low-temperature cutoff.

4.2 Cosaint Íseal-Theochta
The battery features an enhanced low-temperature cutoff:
- Charging is cut off at 32°F (0°C) and below.
- Charging resumes at temperatures above 32°F (0°C).
- Discharging is cut off at -4°F (-20°C) and below.
Disabling low-temperature protection can lead to lithium plating, permanent capacity loss, dendrite growth, separator penetration, and potential thermal runaway.

4.3 One-Touch Switch for Storage
Utilize the one-touch safety switch to cut off power when the battery is unused for extended periods. This prevents over-discharge and extends the battery's lifespan. Always use this switch to shut down the battery during installation, maintenance, or inspection for zero voltage sábháilteacht.
5. Fabhtcheartú
For detailed troubleshooting steps and solutions to common issues, please refer to the official Troubleshooting Guide PDF available anseo.
Common issues may include:
- Gan Cumhacht: Check the one-touch safety switch to ensure it is in the 'ON' position. Verify all cable connections are secure.
- Saincheisteanna Muirir: Ensure the charger is properly connected and receiving power. If charging in cold conditions, the low-temperature cutoff may prevent charging until the battery warms up.
- Nascacht Bluetooth: Ensure only one monitoring device (APP or LCD) is attempting to connect at a time. Check the range between the monitor/phone and the battery.
