For a complete charge of a 12V LiFePO4 battery, a charger with a voltage ranging of 14.4V±0.2V 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.
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.
The 14.6V 20Ah 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 20A current, it takes around 100Ah/20A=5hrs to fully charge a 12V 100Ah LiFePO4 lithium battery.
Charging a battery to less than 100% and avoiding complete discharge always increases cell longevity. Similarly, maintaining operation within the 20%-80% state of charge (SoC) range will prolong the life of lithium batteries.
In the case of LiTime deep cycle lithium batteries, they can withstand 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.
If the correct voltage limit is set for the LiFePO4 lithium ion battery you are charging, there should be no issue leaving a lithium ion battery on the charger overnight. LiTime Battery uses a LiFePO4 cell giving a nominal voltage of 12.8v and a fully charged voltage of 14.6V. A charger with 14.4-14.6V CC/CV output will do the job with consideration not to exceed roughly 1C maximum current output of the charger. As long as the CC/CV profile is used, the maximum voltage is at the correct level and the current is not excessive, you will achieve a safe and full charge on your battery.
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.
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 volts charger is recommended for 24V LiFePO4 lithium batteries.
No. This 20A lithium battery charger is designed only for LiFePO4 batteries. For charging Lead-Acid, LiFePO4, or NCM batteries, we recommend using our LiTime Multi-Bank Chargers, including 12V+24V 10A, 12V+36V 10A, 12V 10A 2-Bank, 12V 10A 3-Bank, and 12V 10A 4-Bank.
Charger works very well. Heavy duty Charger and wiring. Well pleased with this product.
Amazing performance...fast and efficient changing easy set up and use.
This charger is a perfect accessory for our LiTime battery. We are on our third cycle, and have not have any issues with it. Another review we read before purchasing claimed it would over heat. We have not experienced any of this. It remains cool enough to handle, and cables and connections show no sign of overheating.
So far, so good! I have charged 2 lithium batteries so far and it has performed perfectly. Glad I got the 20A for the 100aH and 140aH batteries.
I have no bad complaints so far with this charger it’s the same quality if not better than the expensive ones! It does the job fast!
Using this 20 amp charger with my LiTime batteries, the battery's BMS always shuts the charger down instead of the charger getting into the later stages of the charge where it reduces the amps
Dear Support,
I am attempting to run two LiTime 100 Ah in parallel, however, when I turn on the inverter only one battery discharges. I fully charged each battery before connecting them. Also, after connecting them in parallel I allowed them to balance before putting on a load. When I turn on the inverter with a small load (light and fan), only one battery takes the load and the other one stays on standby. Where am I going wrong?
