FAQ
No, 12V lithium ion batteries require a specific charger designed for lithium-ion technology to prevent overcharging and ensure safety.
To charge our 12V LiFePO4 battery, the charging devices should meet the conditions as below:
1)Support LiFePO4 battery charging mode
2)The charging voltage is between 14.2V to 14.6V
3)The charging current shoule be less than the BMS which could withstand.
If so, then it won't be a problem to charge the 12V batteries.
For more information, read about the article: Can I Charge a Lifepo4 Battery With a Lead Acid Charger?
Not recommended, as lead-acid chargers may affect the performance of lithium batteries. It is advised to use a dedicated lithium battery charger to maximize battery performance.
It is not suggested to completely discharge LiFePO4 batteries. Although these batteries may withstand deeper discharges better than lead-acid batteries, constantly draining them to 0% might shorten their life and performance. It is advisable to recharge the battery before it dips to a very low level, preferably 20% or more.
Yes, Power Queen LiFePO4 batteries may be recharged to 100%. Unlike other lithium battery chemistries, LiFePO4 batteries are engineered to withstand complete charges without severe harm. However, for maximum longevity, it is frequently recommended to keep the battery's SOC between 20% and 80% during normal operation.
For more information, you can read the article: Storing LiFePO4 Batteries: A Guide to Proper Storage.
Pls don't worry.
If the charger or battery is malfunctioning, it is recommended to replace either the charger with the original battery or the battery with the original charger and test again to determine whether the issue lies with the charger or the battery.
To better analyze your issue, since requirements may vary depending on the situation, please check the information below, I will offer my support to you:
1.May I know your order number?
2.What’s the model of charger you are using?
3.Could you please let me know the resting voltage of your batteries?
• The voltage needs to be tested at rest (with zero current) after 3 hrs of disconnecting from the charger & loads.
4. How can you tell if the battery is draining quickly? Please provide the load power and usage duration when the battery does not reach full capacity.
