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. 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.
3. 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.
4. 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.
5. 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
6. Can I charge GoldenMate LiFePO4 lithium batteries with solar panels?
Yes, you can charge GoldenMate LiFePO4 lithium batteries with solar panels. There are 3 ways to charge.
1. Using Solar Panels
The battery can be fully charged in one day (with effective sunshine 4.5 hrs/day) by 300W solar panels. It may take more than one day to fully charge the battery by ≥300W solar panels since the duration and intensity of light would be a great factor for their charging efficiency.
Besides solar panels, there are 2 more ways to charge.
2. Generator/Alternator
If the alternator or generator supports DC output, a DC-to-DC charger is needed to connect the battery to the generator; if your alternator or generator supports AC output, please add a suitable battery charger to connect the battery and the generator according to our recommendations. The Recommended Charging Voltage: 14.2V - 14.6V. The Recommended Charging Current: ① 20A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 50A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.
3. LiFePO4 Smart Chargers
To charge 12V battery, it is recommended to use 14.6V battery charger.
The Recommended Charging Voltage: 14.2V - 14.6V.
The Recommended Charging Current: ① 20A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 50A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.
