Q1: What are the environmental features of this battery?
The battery is made from lithium iron phosphate (LiFePO4), an environmentally friendly material that does not contain heavy metals or rare metals.
It is safe and stable, not prone to burning or exploding under high temperatures, impacts, or short circuit conditions.
It is safe and stable, not prone to burning or exploding under high temperatures, impacts, or short circuit conditions.
Q2: What safety features does the battery include?
The battery includes a comprehensive Battery Management System (BMS) that offers protections against over-charging, over-discharging, and over-current, ensuring safe and reliable operation.
Q3: What's the function of the Bluetooth?
The Bluetooth can track the status of the battery, including SOC, charging/discharging state, battery voltage, current, power, remaining capacity, battery temperature, cycle times etc.
It can also control the battery's discharge and shut down the battery.
It can also control the battery's discharge and shut down the battery.
Q4: Does the BMS have low temperature charging disconnect?
Yes, our BMS has low temperature protection cut-off function to protect the battery from low temperature damage and extend its life.
Low temp cut off protection (Charge): 0℃ ± 4℃ (32°F ± 7.2°F)
Low temp cut off protection (Discharge): -20℃ ± 4℃ (-4°F ± 7.2°F)
Low temp cut off protection (Charge): 0℃ ± 4℃ (32°F ± 7.2°F)
Low temp cut off protection (Discharge): -20℃ ± 4℃ (-4°F ± 7.2°F)
Q5: How to activate the battery when the BMS cuts it off for protection?
If the BMS has cut off the battery for protection, you will need to disconnect any loads connected to the battery and set it aside for approximately 30 minutes.
After this period, the battery will automatically recover to its normal voltage and can be used again after being fully charged.
After this period, the battery will automatically recover to its normal voltage and can be used again after being fully charged.
Q6: How long do BetterESS batteries last?
Our LiFePO4 lithium iron batteries can provide 4000+ cycles, which is significantly more compared to the 300–500 cycles typically found in lead-acid batteries.
The service life of LiFePO4 batteries is 8 to 10 times longer than standard lead-acid batteries.
The service life of LiFePO4 batteries is 8 to 10 times longer than standard lead-acid batteries.
Q7: What are the installation requirements for this battery?
The battery can be installed in any position as it does not contain acid.
Ensure that the battery is securely mounted to prevent vibrations and impacts during movement.
Ensure that the battery is securely mounted to prevent vibrations and impacts during movement.
Q8: Are there any special handling or maintenance tips for this battery?
The LiFePO4 battery requires minimal maintenance.
However, it is recommended to regularly check connections and ensure the battery is kept in a dry and ventilated space.
Avoid exposure to extreme temperatures to prolong battery life.
