5. Boosting Performance: Can LiFePO4 Batteries Be Connected in Parallel?

5.1 Understanding the Parallel Connection of LiFePO4 Batteries

To begin with, it’s essential to understand that when two or more lithium iron phosphate batteries are connected in parallel, the current flowing through each battery won’t be precisely the same. This imbalance increases as the load grows larger, and becomes more pronounced as the number of cells connected in parallel increases. This is due to each cell’s unique internal resistance, affecting the rate at which it receives and generates power.

5.2 Factors Contributing to Current Imbalance in Parallel Connection

The current imbalance between cells after parallel connection is caused by various factors. These include differences in cell and battery manufacturing processes, discrepancies in cell connection resistance, and temperature variations between cells. As such, the State of Charge (SOC) of each LiFePO4 cell connected in parallel may differ from the others for most of the battery system’s life.

In some situations, abnormally high eddy currents may flow between cells, causing the cells to enter an unpredictable protection mode. Though a Battery Management System (BMS) can manage parallel bypass current imbalance and eddy current runaway, it does not resolve the problem entirely.

5.3 Considerations for Parallel Connection of LiFePO4 Batteries

If you’re considering connecting batteries in parallel, keep the following considerations in mind:

5.3.1 Ensure Uniformity in Batteries

Do not mix different brands, capacities, or ages of batteries. The batteries being connected should have identical internal resistance, capacity, voltage, and brand. Mixing batteries of different capacities can cause current imbalance and lead to overheating, affecting the entire electrical system.

5.3.2 Fully Charge the Batteries

Ensure that all LiFePO4 batteries to be connected in parallel are individually fully charged. This creates a balanced state, maximizing your overall usage time.

5.3.3 Use Suitable Connection Cables

The cable sizes should be suitable for carrying the required current. They should match the size of your maximum requirements and ideally, should be as short as possible. Also, the cables connecting the batteries should be large enough to carry the total current of the system.

5.3.4 Proper Battery Connection

Finally, connect the positive terminals together and perform the same operation for the negative terminals. The positive terminal of the first cell and the negative terminal of the last cell should be connected to the system.

5.4 The Risks of Mixing Old and New Batteries

Connecting old and new batteries in parallel can be problematic. As batteries age, their internal resistance gradually becomes unbalanced. The newer battery, having a lower internal resistance than the old one, charges and discharges at a higher current than the other battery, aging faster to reach a similar state as the older battery. This affects the service life of the new battery.

5.5 Aolithium LiFePO4 Batteries and Parallel Connection

Aolithium batteries can be connected in parallel under certain conditions. The batteries should be of the same capacity, from the same batch, brand new, and fully charged before paralleling. It’s the only way to ensure the internal characteristics of the batteries are similar, making them suitable for parallel connection. Connecting two batteries at a time, preferably bought simultaneously, is the best option for those planning to connect the batteries in parallel.

In conclusion, the parallel connection of LiFePO4 batteries can boost performance and power. However, care must be taken to ensure the batteries are compatible and handled correctly to prevent damaging the batteries or the entire electrical system.

6. Perfect Fit: Determining What Size LiFePO4 Battery I Need

6.1 Understanding the Application and Power Requirement

When choosing the size of a LiFePO4 battery, the first step is identifying the application, such as your car, 4WD, caravan, boat, or RV. Then, you need to determine how much power you need and for how long. For instance, if your application draws 10 Amps for 10 hours, you will need at least a 100Ah battery. However, to ensure a long battery life, it’s advisable to aim for a lower discharge level.

6.2 The Realities of Lithium Batteries

Lithium batteries can seem like a magical energy source that can produce endless power, especially when compared to old lead-acid batteries. However, the reality is a bit different. Two key points to remember are: the deeper you discharge a lithium battery, the shorter its cycle life; and the faster you charge a lithium battery, the shorter the battery life.

6.3 The Importance of Correctly Sizing Your Battery

LiFePO4 batteries are different from lead-acid batteries in that you can discharge them much further and still get a long life. However, if you constantly discharge them to 100%, you seriously reduce the cycle life. Conversely, at 50%, you can get an extremely long life.

As such, correctly sizing your battery for your application is important for ensuring a system that will last long enough to justify the higher cost of lithium. Using the example of a 100Ah draw over 10 hours, a 120Ah battery could provide some buffer, reducing the depth of discharge point from 100% to closer to 80%. Alternatively, a 200Ah battery would only need to be discharged to 50%, leading to a significantly longer life.

6.4 The Advantages of Lithium Batteries

One of the great things about lithium batteries is that the whole battery capacity is usable. Yes, repeatedly using the full capacity can shorten the life, but nowhere near as much as with traditional lead-acid batteries, which don’t like being discharged more than 50%. With lithium, if you need the extra power, you can use it!

7. Myth or Fact: Do LiFePO4 Batteries Explode?

7.1 Understanding Potential Dangers

LiFePO4 batteries are generally safe for use under normal conditions. However, in extreme cases, issues can arise that might lead to dangerous situations, potentially even explosions. These include overcharging, the material composition of the battery, and where the battery is placed while charging.

Overcharging can lead to internal heat buildup in the battery, which could cause a fire if the battery is insulated and the heat can’t escape. The battery’s material also impacts its thermal and structural stability. Furthermore, charging batteries in combustible environments can lead to fires, even with small heat generation.

7.2 Preventive Measures

Preventing such hazardous situations involves using an appropriate charger for your battery type and voltage rating. This can help avoid overcharging and heat generation. Additionally, storing and charging your batteries at suitable temperatures (generally between 15 °C and 30 °C) can prevent overheating.

Employing a good Battery Management System (BMS) is also crucial when using battery packs with multiple LiFePO4 cells. A BMS can halt charging at peak voltage and charge each cell individually, detecting any cells that are malfunctioning.

Finally, sourcing your batteries from reputable manufacturers is a good practice to ensure pre-production tests have been adequately conducted. One such manufacturer, nRuiT-Power, an authorized CATL energy storage system integrator, offers high-quality lithium battery energy storage solutions.
