FAQs
1. Are GoldenMate LiFePO4 lithium batteries safe?
Yes. GoldenMate LiFePO4 batteries use one of the safest and most stable lithium chemistries available. They are UL-certified and include an advanced Battery Management System (BMS) that protects against over-charge, over-discharge, over-current, overheating, and short circuits. They are also tested to minimize risks of fire and electric shock, even in harsh environments.
2. Can GoldenMate LiFePO4 batteries be used as starting batteries?
No. These batteries are designed for energy storage, not engine starting. Do not use them to start vehicles or devices that require high instantaneous cranking current.
3. How can I charge GoldenMate LiFePO4 batteries?
GoldenMate LiFePO4 batteries can be charged in several ways:
- Solar panels (recommended ≥300W for faster charging)
- Generator or alternator (DC-to-DC charger required for DC output)
- LiFePO4 smart chargers
Recommended charging voltage is 14.2V–14.6V. Using a 20A charger typically takes about 5 hours, while a 50A charger can reach ~97% charge in about 2 hours.
4. How long does it take to charge the battery?
Charging time depends on the charger:
- 10A charger: ~10 hours
- 20A charger: ~5 hours
- 50A charger: ~2 hours (to ~97%)
Solar charging time varies based on sunlight intensity and duration.
5. Can I charge the battery in cold temperatures? Does it have low-temperature protection?
The battery includes low-temperature charging protection, which prevents charging below freezing to avoid cell damage.
Recommended charging temperature range is 32°F–122°F (0°C–50°C). Charging below 32°F (0°C) is not recommended.
6. How should I store the battery, and what should I do when I receive it?
The battery may arrive with a low state of charge due to shipping. Please charge it promptly after receiving.
For storage:
- Store at ~50% state of charge (SOC)
- Store in a dry environment between 50°F–95°F (10°C–35°C)
- If stored long-term, recharge or cycle the battery every 3–6 months to maintain performance
