For a complete charge of a 12V LiFePO4 battery, a charger with a voltage ranging from 14.2V to 14.6V is necessary. If a charger with a lower voltage is used, it can still charge the battery, but it won't reach full 100% capacity.
Can I charge a LiFePO4 battery with a trickle charger?
Trickle charging is not acceptable for lithium batteries. Charging a LiFePO4 battery with a trickle charger not designed for this type of battery could lead to overcharging or damage due to the different charging requirements of lithium batteries compared to traditional lead-acid batteries.
How long does it take to charge a 12V 100Ah LiFePO4 lithium battery?
The 14.6V 10Ah LiFePO4 battery charger is designed to charge LiFePO4 batteries. The low resistance in the Lithium cells allow the battery to accept the full output from the charger. With a constant 10A current, it takes around 100Ah/10A=10hrs to fully charge a 12V 100Ah LiFePO4 lithium battery.
Is it OK to leave a LiFePO4 lithium battery on the charger?
Leaving a lithium-ion battery on the charger overnight should be safe if the charger is set with the correct voltage limit for the type of lithium-ion battery being used. For instance, with a LiFePO4 cell like the one used in LiTime Battery (with a nominal voltage of 12.8v and a fully charged voltage of 14.6v), using a charger with a 14.4-14.6v CC/CV output should work, provided it doesn't exceed roughly a 1C maximum current output. By following the CC/CV profile, ensuring the voltage is correct, and the current isn't excessive, you can safely achieve a full charge for your battery.
How fast will my battery charge?
To determine your charging speed, take the amp hour rating of your battery and divide it by the output current of your charger. For example, a 100 amp hour battery (Ah) would charge in 100AH/10A=10 hours with a 14.6V 10A LiFePO4 lithium battery charger.
Can I charge my LiFePO4 lithium battery faster?
For most applications, a charging time of 3-10 hours provides the longest lifespan for your LiFePO4 lithium battery. But if you have an application where you need rapid charging, you can choose a charger with a higher output current. For example, you could use a 40 amp charger with a 100Ah battery for a 2.5-hour charge time.
What voltage should LiFePO4 lithium batteries be charged at?
It depends on the voltages of your LiFePO4 lithium batteries. LiTime 14.6 volts charger is recommended for 12V LiFePO4 lithium batteries. And LiTime 29.2 volt charger is recommended for 24V LiFePO4 lithium batteries.

Hamjazz
I’ve been using the battery primarily as an emergency power backup at home — it gives me peace of mind knowing I’ve got reliable energy if the grid goes down.
Fish Big
The lightweight design is a game-changer for someone like me, who spends a lot of time outdoors. I use this battery regularly to power all my electronics during trips, and it has never let me down.

Great addition to our travel trailer. Now we can spend endless time at a remote campsite without worrying we will run out of power.
James
Omg awesome!
Things are looking great so far. With all the great reviews on the web. I’m feeling pretty good about the two 200 AH batteries I bought. Thank you for a great product
Allan
Fairly light weight at 80 lbs. Only took about a day to fully charge with solar panels, and it runs my 3000 W inverter with no issues. 400ah is well worth getting instead of 4-100ah batteries connected together due to less wiring and possible loose connections. Highly recommend.
Donald L Anderson
Installed 2 100ah batteries in boat as my house bank with the Litime DC to DC 40amp charger to protect alternator. I have to say very happy with everything.
