FAQs
Q: Is it OK to leave a LiFePO4 lithium battery on the charger?
A:
If the correct voltage limit is set for the LiFePO4 lithium-ion battery, it is safe to leave the battery on the charger overnight. Timeusb Battery utilizes a LiFePO4 cell with a nominal voltage of 25.6V and a fully charged voltage of 29.2V. A charger with a 28.8-29.2V CC/CV output is suitable. As long as the CC/CV profile is followed, the maximum voltage is correct, and the current is not excessive, your battery will charge safely and fully.
Q: What voltage should LiFePO4 lithium batteries be charged at?
A:
The appropriate charger depends on the voltage of your LiFePO4 lithium batteries. For 24V LiFePO4 batteries, the recommended charger is the Timeusb 29.2V charger.
Q: Should I charge LiFePO4 to 100%?
A:
Yes, you can. However, charging a battery to less than 100% and avoiding complete discharge will always enhance cell longevity. Similarly, keeping the state of charge (SOC) between 20% and 80% will extend the lifespan of lithium batteries. For instance, Timeusb deep cycle lithium batteries can endure over 4000 deep cycles at 100% Depth of Discharge (DOD), over 6000 cycles at 80% DOD, and more than 15,000 cycles at 60% DOD.
Q: What charger should I use for LiFePO4 battery?
A:
To fully charge a 24V LiFePO4 battery, you need a charger with a voltage between 28.4V and 29.2V. Using a charger with a lower voltage will still charge the battery, but it won't reach 100% capacity.
Q: Can I charge a LiFePO4 battery with a trickle charger?
A:
Trickle charging is not suitable for lithium batteries. Using a trickle charger not specifically designed for LiFePO4 batteries can cause overcharging or damage because lithium batteries have different charging requirements compared to traditional lead-acid batteries.
