With the advantage of super long cycle life, ELB has provided innovative LiFePO4 batteries solutions for all kinds of application.
The special batteries provides high -circulation life and excellent performance at a wide range of working temperature.
The LiFePO4 battery is the safest lithium battery type in the market. Compared with sealing lead acid, the nominal voltage of the LiFePO4 battery are range from 3.2V to 500V, and the capacity are range from 2Ah to 280Ah.
LiFePO4 batteries also called LFP batteries, which are a type of lithium battery also. Since the batteries are using lithium iron phosphate as the positive electrode material, so it is called LiFePO4 batteries.
LiFePO4 batteries is now known as the safest, most stable and most reliable lithium battery.

|Cost||~$200 per kWh|
|Applications||ESS, EVs, etc|
The electrodes (lithium and carbon) commonly used in LiFePO4 batteries are inherently light. Making them smaller and lighter than older batteries such as lead-acid batteries. For comparison, a typical 100Ah (= amp hour) Li-Ion battery weighs about the same as a 40Ah lead-acid battery (about 10-12kg). But has more than twice the capacity.
Maximize your energy potential with 100% Depth of Discharge. This means that you can use 100% of the battery’s capacity to power your specific needs. Horever, Lead-acid/ AGM batteries slowly decrease their power and performance while the charge depletes.
Lithium has the ability to release and store large amounts of energy. Enabling lithium iron phosphate batteries to package high energy capacity in a small size. This means that a lithium battery of the same weight will last much longer between charges than other rechargeable batteries. While still maintaining its high level of performance.
Older rechargeable battery types, such as nickel-cadmium or nickel-metal hydride batteries, have what’s called the “memory effect” or “inert cell effect”. If repeatedly partially discharged before charging, the final battery can only supply locally before the voltage drops. Energy used during discharge. To avoid this, NiCd and NiMH batteries need to be fully discharged and recharged on a regular basis for maintenance.
LiFePO4 batteries don’t suffer from memory effect, which means they always use up the last bit of charge. Whether you’re using 100% or 25% capacity, you can charge them without tedious maintenance!
High-quality lithium iron phosphate batteries last for about 4000 full charge cycles. A full charge cycle is when the battery is discharged to depletion and then charged to full, so using the battery until it reaches 75% capacity and then plugging it in to charge does not constitute a full charge cycle. When your battery is recharged, you can still use 75% of the charge remaining before charging; only then can your battery complete a full charge cycle.
Lithium batteries also have relatively low self-discharge rates. Self-discharge is a natural, irreversible phenomenon for batteries, where chemical reactions inside the battery reduce the capacity of the battery, even when the battery is not being used. The self-discharge rate of Li-ion batteries peaks at around 3% in the first 24 hours after charging, and then gradually decreases to 1-2% per month. In comparison, nickel-based rechargeable batteries lose about 10-15% of their capacity after charging, and another 10-15% per month.
While the battery is discharging and providing an electric current, the anode releases lithium ions to the cathode, generating a flow of electrons from one side to the other.
When plugging in the device, the opposite happens: Lithium ions are released by the cathode and received by the anode.
This process creates an electrical current that powers the electronic devices.

After you get the right charger, charging your battery is a cinch. Here’s what to do, step by step:
1. Make sure the battery terminals are clean. Remove any grease and dirt.
2. First, connect the red (positive) cable to the red terminal. Then connect the black (negative) cable to the black terminal. Make sure cables are tightly connected to the battery terminals.
3. Plug in the charger. And switch on.
4. If using a smart charger, you can “set it and forget it”. It will stop charging on its own. Most lead acid chargers require setting a timer and disconnecting the charger when the battery is charged. But for lithium batteries, it is not necessary since there are BMS protection function.
5. To disconnect, unplug the charger. Remove the black cable, then the red one.

In most cases, we need to connect the batteries in series or parallel to increase the voltage, or increase the capacity to prolong the service time. How to connect the batteries in series and parallel? For details, please visit our article<How to connect batteries in series vs parallel?>
