What charger should I use for LiFePO4 battery?

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 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.

Should I charge LiFePO4 to 100%?

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.

Is it ok to leave a LiFePO4 lithium battery on the charger?

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.

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 volts charger is recommended for 24V LiFePO4 lithium batteries.

How to choose the right charger for my LiFePO4 lithium battery?

It is always important to match your charger to deliver the correct current and voltage for the LiFePO4 lithium battery you are charging. For example, you wouldn't use a 24V charger to charge a 12V LiFePO4 lithium battery. It's also recommended that you use a charger matched to your battery chemistry. Additionally, when charging a LiFePO4 lithium battery with a normal lead-acid charger, you would want to ensure that the charger does not have a desulfation mode or a dead battery mode.

Works great!!

Good battery but BT software could be improve.

BT software is not public and I cannot write my own application to set periodic notification, alarm, monitor event and power draw. This is crucial for me as the battery is used for a sump pump used as a critical security backup. I did order some electronic part to built/progam my own BT surveillance device.

20 amp lifepo4 Charger.

I have several cheaper chargers that can charge lithium but after I bought the Li Time 100 ah group 24 smart battery I decided to get a charger specific for the battery.
It came on time and works as described.
The max charge I have seen is just above
19 amps which is close enough for me.
I also have a 200ah lifepo4 from another company and this charger will be used for that.

I am very happy with my Li Time battery as it runs a trolling motor when at home.
It will run my fridge when travelling

I will be buying a second group 24 to put in series and create a 24 volt system in the near future.

More work for the charger when the solar needs some help

100amp/hr battery, 20 amp charger and battery box

I have the little 100 amp/hr battery 12v
The 20 amp charger and battery box. All Litime products.
I need a second battery but waiting to use this more times.
I've used it for 3 days out ice fishing on a Garmin livescope and never run the battery out.
That was a total of 36hrs on .. so far it's been fantastic.
I just wish I can get the same deal as they do in the United States.
A group of us are looking at purchasing more if it continues to perform as it has.

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.

Esther Snow

Drop in for our travel trailer 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.
