Four Protections To Secure LiFePO4 Battery And Charger
This 14.6V 40A LiFePO4 battery charger has four protections to keep the battery and charger safe, they are high-temperature protection, output short-circuit protection, output over-voltage protection, and reverse polarity connection protection.
Monitor The Charger In Real-Time With An LED Indicator And A Display Screen
Fitted with an LED indicator and a display screen to show the battery voltage, the charging current, and the capacity that has been charged to the battery, it's easy and convenient to figure out the status of the 14.6V 40A LiFePO4 battery charger. You can also quickly troubleshoot the general problem with the charger by following the instructions.
3-Stage Smart Charging Method, Dedicated To LiFePO4 Battery
Timeusb 14.6V 40A LiFePO4 battery charger has a smart charging design, which includes pre charging stage, constant current stage(CC), and constant voltage stage(CV). It can switch charging mode based on the voltage, making it to charge the battery smoothly and safely.
Fast And Highly Efficient Charging With LiFePO4 Battery Activation
The 14.6V 40A charger can fully charge a 12V 100Ah LiFePO4 battery in 2.5 hours. It is one time faster than a 14.6V 20A charger and saves 50% of the time. With the LiFePO4 battery activation function, this charger can activate the battery after the battery's BMS triggers the protection.
Fit For Major Charging Scenarios
This 14.6V 40A lithium battery charger can be used with an on-grid power socket or a generator. It can gratify your charging needs both indoors and outdoors.

FAQs
Q: Is it OK to leave a lithium-ion battery on the charger overnight?
A:
Leaving a lithium-ion battery on the charger overnight is generally safe if you use a charger, such as those from Timeusb, designed to stop charging once the battery is fully charged. Most modern lithium-ion chargers have this feature to prevent overcharging.
Q: Can 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: 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.
What about a regular charger? For more information, refer to the article "Can I Charge LiFePO4 with a Normal Charger?"
Q: What charger should I use for LiFePO4 battery?
A:
To fully charge a 12V LiFePO4 battery, you need a charger with a voltage between 14V and 14.6V. Using a charger with a lower voltage will still charge the battery, but it won't reach 100% capacity.
Q: What voltage should LiFePO4 lithium batteries be charged at?
A:
The appropriate charger depends on the voltage of your LiFePO4 lithium batteries. For 12V LiFePO4 batteries, the recommended charger is the Timeusb 14.6V charger.
