Troubleshooting Common Issues
Issue #1: Battery Not Delivering Full Power (BMS Tripping)
Problem: Your golf cart or inverter suddenly loses power, or the battery seems to cut out under heavy load.
Solution: This is likely the 200A BMS entering protection mode. Check if your continuous draw exceeds 200A or your peak surge exceeds 700A. Use the Bluetooth app to monitor real-time current. Reduce the load and allow the battery to reset.
Prevention: Ensure your motor controller or inverter’s maximum draw is compatible with the 200A continuous/700A peak specification.
Issue #2: Bluetooth App Not Connecting to Battery
Problem: The mobile app cannot find or pair with the battery for remote monitoring.
Solution: First, ensure you’re within range (typically 30 feet unobstructed). Check that the battery’s Bluetooth module is powered (battery should have charge). Restart the app and your phone’s Bluetooth. Verify you’re using the correct app specified by DC HOUSE.
Tech Note: The Bluetooth module is integrated into the BMS; if it fails entirely, contact support as it may indicate a deeper BMS issue.
Issue #3: Included 48V 18A Charger Not Working
Problem: The charger doesn’t power on, shows an error light, or fails to charge the battery.
Solution:
- Verify the charger is plugged into a working AC outlet and the connections to the battery terminals are tight and correct (positive to positive).
- Check the charger’s output matches the battery’s 48V requirement and the battery’s voltage isn’t too low for the charger to recognize (BMS low-voltage disconnect may need bypass).
- Ensure the battery’s internal temperature is within the charger’s operating range; extreme cold can prevent charging initiation.
Issue #4: LCD Monitor Showing Incorrect Voltage or SOC
Problem: The built-in LCD screen displays a voltage that doesn’t match your multimeter or shows an inaccurate state of charge.
Solution: First, calibrate your measurement by checking the voltage directly at the battery terminals with a quality multimeter. A small discrepancy (0.1-0.3V) is normal. If the LCD is wildly off, it may require a BMS reset by disconnecting all loads and the charger for 10 minutes.
Safety Feature: The BMS protects the cells; the LCD reads data from the BMS, so persistent inaccuracy could signal a BMS calibration need.
Issue #5: Reduced Runtime or Capacity Fade
Problem: The battery doesn’t last as long as it used to, failing to reach its rated 5.12kWh capacity.
Solution: Perform a full balance charge using the included 48V 18A charger. Use the Bluetooth app to check individual cell voltages; significant imbalance reduces usable capacity. Ensure you’re not consistently drawing near the 200A limit, which increases voltage sag and perceived capacity loss.
Prevention: The 4000+ cycle life assumes proper use. Avoid consistently draining to 0% SOC and store the battery at a partial charge (50-80%) if not used for extended periods.

Frequently Asked Questions
Is the included 48V 18A charger sufficient for daily use, or do I need a bigger one?
The included 48V 18A charger (approximately 864W) is well-matched for daily use. It can fully recharge the 5.12kWh (100Ah) battery from empty in about 6-7 hours. For most golf cart or RV applications where you charge overnight, this is perfectly adequate. You would only need a larger, faster charger if you require multiple full charges within a single day.
Can I connect multiple DC HOUSE 48V 100Ah batteries in series or parallel?
While the battery is designed as a standalone 48V unit, connecting multiple units requires careful planning. For parallel connection (to increase capacity), you must ensure batteries are at the same voltage before connecting and use proper bus bars. Series connection (to increase voltage) is not recommended without consulting DC HOUSE, as the internal BMS is configured for 48V operation only.
How does the 51.2V output work with my existing 48V golf cart system?
The 51.2V nominal output is standard for a fully charged 48V LiFePO4 battery system (16 cells at 3.2V each). It is directly compatible with 48V golf cart motor controllers, which are designed to operate within a voltage range. Your cart will actually perform better as the voltage remains higher for longer compared to a sagging lead-acid pack that starts at ~50V and drops quickly.
What does the 4000+ deep cycle rating mean in practical terms?
A “deep cycle” typically means discharging the battery to 80-100% of its depth of discharge (DOD). The 4000+ rating means you could theoretically discharge and recharge the battery completely every day for nearly 11 years before it reaches 80% of its original capacity. In real-world use with partial cycles, the operational lifespan could extend well beyond 15 years.
Does the fireproof metal casing make the battery safer than plastic alternatives?
Yes, significantly. The durable fireproof metal casing provides superior physical protection against impacts and punctures. More importantly, in the extremely rare event of a thermal issue, the metal case helps contain and dissipate heat far more effectively than plastic, which can melt or burn. This is a critical safety advantage for installations in vehicles or enclosed spaces.
Can I use this battery as a direct drop-in replacement for my lead-acid golf cart batteries?
Yes, the universal fit design and 51.2V output make it a direct physical and electrical replacement for a standard 48V lead-acid golf cart battery pack. However, you must ensure your existing charger is compatible with LiFePO4 chemistry or use the included 48V 18A charger. The battery will also be significantly lighter than the lead-acid pack it replaces.
