Product Documents
FAQs
Will the WG5127 fit my golf cart?
The WG5127 is a compact 51.2V 27Ah LiFePO4 battery for compatible 48V-class golf carts and utility vehicles. Before ordering, confirm the battery compartment dimensions, terminal layout, cable ratings, controller requirements, and available mounting space. Compatibility depends on the cart’s electrical configuration, not the brand name alone.
Can I use my original lead-acid charger?
No. Use a charger designed for a 51.2V LiFePO4 battery with charging settings that meet the WG5127 requirements. Lead-acid chargers may use incompatible charging profiles, equalization, or temperature compensation and should not be used unless their settings fully match the battery specifications.
Is a charger included with the WG5127?
Package contents may vary by product option. Check the selected configuration and the “What’s in the Package” section before checkout to confirm whether a compatible LiFePO4 charger or other accessories are included.
How long does the WG5127 take to charge?
Charging time depends on the starting state of charge, charger output, battery temperature, and system losses. A compatible 20A LiFePO4 charger can recharge a deeply discharged 27Ah battery in roughly 1.5 to 2 hours under normal conditions, although actual charging time may vary.
What can I monitor through the VolTrust app?
After connecting through Bluetooth, the VolTrust app can display state of charge, pack voltage, current, power, temperature, cycle information, warning status, and individual cell voltage. Available information and Bluetooth range may vary by phone and operating environment.
How does the WG5127 perform in cold weather?
The WG5127 includes low-temperature protection and automatic internal heating. Charging is disabled below 23°F (-5°C) and resumes above 32°F (0°C). During charging, the heater activates below 41°F (5°C) and stops at approximately 59°F (15°C), helping the cells reach a safer charging temperature.
Can I connect WG5127 batteries in series or parallel?
The WG5127 supports up to four matched batteries in parallel to increase capacity while keeping the system at 51.2V. Use batteries of the same model, age, capacity, cable length, and state of charge. Do not connect WG5127 batteries in series.
What discharge output does the WG5127 support?
The WG5127 supports up to 60A continuous discharge and 100A maximum discharge for 5 seconds. Confirm that the golf cart controller, motor, cables, terminals, and expected load remain within the battery specifications before installation.
What should I check before installation?
Turn off all power, verify polarity, confirm cable and terminal ratings, secure the battery against movement, and follow the WG5127 user manual. Take photos and label the existing wiring before removing old batteries. If the controller, regenerative braking, charging circuit, or accessory wiring is unclear, use a qualified technician.
What warranty does the WG5127 include?
The WG5127 includes a 5-year limited warranty. Coverage is subject to the current VolTrust warranty terms, proof of purchase, proper installation and use, and technical review. Review the warranty policy for complete eligibility, exclusions, and claim requirements.
