Upgrade Design Ensures A Better User Experience
The 14.6V 40A lithium battery charger is equipped with a switch, a cooling fan, and mounting holes. You don't have to unplug the AC plug because of the switch. The cooling fan can lower the charger temperature while charging, which is good for the charger's lifespan.
Lightweight & Portable Design
Weighing 6.17lbs and measuring L11.54 x W5.31 x H2.78 in, it's light and portable to charge the LiFePO4 battery anywhere, suitable for your different usage scenarios, including RV, camper, or energy backup system.
Comprehensive Safety Protection For The LiFePO4 Battery
The 14.6V 40A LiFePO4 battery charger has four protections to protect the battery and charger: high-temperature protection, output short-circuit protection, output over-voltage protection, and reverse polarity connection protection.
Easy & Friendly Charging Operations
It's easy to use this charger to charge the LiFePO4 battery and monitor the charging. Even if you are new to electronics, you can successfully connect the charger and battery following our instructions.
Fit For Multiple Charging Scenarios
This 14.6V battery charger can be used with an on-grid power socket or an alternator. It can satisfy your multiple charging situations, whenever you are on a RV trip or camper outside.
Why Timeusb LiFePO4 Battery Charger?
Compared with the 14.6V 40A lead-acid charger, Timeusb 14.6V 40A LiFePO4 battery charger has a battery activation function, it can activate the LiFePO4 batter after the BMS protection.

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.
