Best Way to Charge A LiFePO4 Lithium Battery

03 Dec 2022
Best Way to Charge A LiFePO4 Lithium Battery - LiTime

Battery scientists talk about energies flowing in and out of the lithium battery as part of ion movement between anode and cathode, which makes the charging and discharging of lithium batteries an exception from the chemical reaction of traditional lead acid batteries. While lead acid offers some flexibility in terms of voltage cut-off, the LiTime lithium battery cells are very strict on the correct setting to prevent overcharging along with the LiTime LiFePO4 lithium charger to prolong the battery life.

Recommended LiFePO Lithium Battery Charger

Two things should be attention:

1. Always remember to match your charger to deliver the correct current and voltage for the lithium battery you are charging. For example, use a 12V lithium charger to charge a 12V lithium battery.

2. Always use a charger matched to your battery chemistry, so we recommend you use a dedicated LiFePO4 lithium charger to charge LiTime LiFePO4 lithium batteries.

3 Best Ways to Charge LiFePO4 Lithium Batteries

If you’re looking to get the most out of your LiFePO4 lithium battery while still maintaining its performance, then knowing the best ways to charge a LiFePO4 battery will make it a worthwhile investment.

1. Using A Lithium Battery (LiFePO4)

The ideal way to charge a LiFePO4 lithium battery is using a dedicated lithium iron phosphate battery charger, as it will be well programmed to protect the battery. LiTime LiFePO4 battery charger can provide multilevel protections to prevent Over Temperature, Over Voltage, Short Circuit, and Reverse Polarity.

2. Using Solar Panels

Whether in a home, a boat, or an RV, using a solar energy system to charge LiFePO4 batteries is highly recommended.

The charging process involves 4 steps:

① Solar panels: convert sunlight into electrical energy.

② Charge controller: regulates the power output of the solar panels according to the battery’s charging requirements, avoiding battery overcharge.

③ Battery: stores the energy provided by the solar panels.

④ Inverter: converts direct current (produced by solar panels) into alternating current (which the appliances can use).

3. Using a generator with a DC-DC charger

A DC/DC charger limits the current drawn from the generator, avoiding the overheating issue. It also regulates the output voltage to the required charging voltage of the LiFePO4 lithium battery, protecting it from overcharging.

What Is The Safest Way To Charge A LiFePO4 Battery?

Unlike other lithium battery chemistries, the LiFePO4 is very safe due to its superior thermal and chemical stability.

As a result, lithium iron phosphate cells are much harder to ignite. This is an important feature that makes them far superior to other Lithium battery chemistries.

The safest way to charge these batteries would be respecting the exact specifications of the battery, in terms of voltage, optimal charging temperature, use of appropriate wires, etc, whether you use a LiFePO4 charger, a solar system, or any other way.

Tip: Always check your battery’s manual to see what the manufacturer recommends in terms of charging.

Can I leave the LiTime lithium battery on charging all the time?

For a lithium battery with a low maintenance charging procedure and battery management system, it's perfectly fine and better than leaving them discharged for a long period. The LiTime LiFePO4 batteries have a charging cut-off voltage, which means that it will stop charging at a certain volt. 

How fast can I charge my battery?

Calculate the charge time by dividing the capacity of the battery (Ah for Amp Hours) by the charger output (A for Amps). For example, a 12V 100Ah LiTime LiFePO4 Lithium Battery can be charged from empty to full in 10 hours with a LiTime 12V 10A LiFePO4 charger (100 Ah divided by 10 A = 10 hours).
