When it comes to batteries, there are various options available, each with their own pros and cons. The choice of battery depends on factors such as the size and demands of your particular model. In this article, we will explore the major differences between LiPo batteries and LiFe batteries. Both types can be recharged, offering significant advantages over disposable batteries. However, LiFE batteries are generally considered safer as they cannot be overloaded or easily damaged, reducing the risk of fire. LiFE batteries also tend to last longer, with more charging cycles. On the other hand, LiPo batteries offer higher speeds and greater efficiency, making them ideal for demanding models.
Differences Between LiFe and LiPo Batteries:
1. Chemistry and Packaging: LiPo batteries have a chemistry that results in a nominal voltage of 3.7V and 4.20V when fully charged. LiFe batteries have slightly different chemistries but are typically 3.3V nominal. However, the voltage can vary depending on the specific type of LiFe battery.
2. Safety: LiFe batteries are generally safer as they are less likely to explode or catch fire when depleted, overloaded, or physically damaged. LiPo batteries, on the other hand, can be hazardous if not handled properly.
3. Storage: LiFe batteries can be stored fully charged without significant performance loss, whereas LiPo batteries should always be stored at 50% capacity or less if not in use for an extended period.
4. Packaging: LiFe batteries usually come in round metal cans, similar to nickel-based batteries, while LiPo batteries come in soft casings. LiPo batteries are typically rectangular in shape and come in a wider range of sizes and capacities.
5. Energy Density: LiPo batteries have a higher energy density than LiFe batteries. For example, a 3S 3900mAh LiPo battery weighs the same as a 3S A123 LiFe battery with only 2300mAh capacity. This means LiPo batteries offer more energy in the same size and weight.
6. Charging Rates: LiFe batteries, especially A123 brand batteries, can be charged at high rates, up to 10C. LiPo batteries used to have a charging rate of 1C, but now there are many options with higher charging levels.
Are LiFe Batteries Safer Than LiPo Batteries?
LiFe batteries are generally considered safer than LiPo batteries. LiFe batteries are less likely to catch fire or explode even if punctured. The cathode material in LiFe batteries is not toxic, making them safer for the environment. LiFe batteries have a lower energy density compared to LiPo batteries, but they are more readily available and cost-effective. The lifespan of LiFe batteries is typically around 5 to 7 years.
Caring for LiFe and LiPo Batteries:
To ensure the longevity and safe use of LiFe and LiPo batteries, it is important to follow these guidelines:
1. Never damage the battery by hitting sharp edges, opening or distorting the cell’s folding top, dropping, striking, or bending it.
2. Never incinerate or dispose of batteries in a fire. This can cause the cells to explode.
3. Always use a lithium polymer or lithium-ion battery charger specifically designed for these types of batteries.
4. Charge batteries in a well-ventilated area away from flammable materials.
5. Avoid charging batteries in freezing temperatures or when they are hot to the touch.
6. Properly dispose of dead batteries and regularly check for any damage before charging.
7. Store batteries at room temperature in a cool, dry place. Do not store them in a refrigerator.
8. Avoid disassembling, smashing, puncturing, or damaging batteries, as this can lead to leakage or failure.
