Battery operated electric lawn mowers are available with one of two main battery types, lithium-ion, and LiFePO4. When we compare these two in terms of lifespan, performance, safety, and cost, we see that both have their pros and cons. LiFePO4 batteries last longer, but they also cost more.
Mowrator Australia will give you a few points to bear in mind when choosing between lithium ion and LiFePO4 battery mowers. Once you know the advantages and disadvantages of each one, you can make a more informed decision when purchasing your next battery operated lawn mower.
According to Lithium Hub, lithium-ion batteries do have a small risk of overheating and even catching on fire. These risks are what lead to the creation of LiFePO4 batteries, which are considered much safer and more effective in various ways. Let’s examine what other benefits they hold, and whether they are a better choice for your next lawn mower.
Key Takeaways
- Compared to lithium-ion batteries, LiFePO4 batteries in lawn mowers can be recharged more times.
- LiFePO4 batteries also charge around 2 hours faster than lithium-ion, allowing users to mow larger areas.
- Lithium-ion batteries are typically more compact than LiFePO4 batteries.
- LiFePO4 batteries are more eco-friendly in how they are manufactured and how much power they consume.
What is the Primary Difference Between Li-ion and LiFePO4 Batteries?
The primary difference between Li-ion and LiFePO4 batteries is how they are designed. LiFePO4 batteries are more advanced, offering better safety, a longer lifespan, and an increase in charge rotations. On the other hand, Li-ion batteries are cheaper and lighter, but they still need to be replaced often. LiFePO4 batteries are also more environmentally friendly compared to Li-ion batteries.
This makes LiFePO4 a better option for battery operated lawn mowers. They discharge more power, last longer, and offer better safety in high performance machines that tend to get hot. Here’s a breakdown of the two battery options:
| Feature | Li-ion | LiFePO4 |
|---|---|---|
| Lifespan | 500 to 1,000 charge cycles before significant degradation | 2,000 to 5,000 charge cycles, making it the longer-lasting option |
| Safety | More prone to thermal runaway (overheating, potential fire risk) | Much more stable and resistant to overheating; safer than Li-ion |
| Performance | Higher energy density, meaning a lighter battery for the same power output | Slightly heavier but maintains consistent voltage longer under load, ideal for sustained mowing power |
| Charging and Efficiency | Charges faster but loses efficiency as it degrades | Takes longer to charge but maintains efficiency over a longer period |
| Cost | Cheaper upfront but requires more frequent replacement | More expensive, but offers more value for the initial investment |
Which Battery Type Offers a Longer Lifespan in Electric Lawn Mowers?
LiFePO4 batteries offer a longer lifespan in electric lawn mowers than any other battery. Thus far, there has not been a more advanced battery designed to handle high-energy-output machines like lawn mowers for long periods of time. Their ability to maintain a consistent voltage makes them a reliable choice for high-demand outdoor equipment.
Are LiFePO4 Batteries Safer than Lithium-Ion Batteries?
Yes, LiFePO4 batteries are safer than lithium-ion batteries. They can withstand heat much better, and have a substantially lower risk of overheating and igniting. LiFePO4 batteries are now the preferred choice for outdoor machines like lawn mowers, because they handle hot weather conditions and high machine temperatures effectively.
Do Li-ion Batteries Provide More Power than LiFePO4 Batteries?
No, Li-ion batteries do not provide more power than LiFePO4 batteries. However, they do typically hold more energy in relation to their size. Lithium-ion batteries are more compact, but this benefit doesn’t outweigh the multitude of other benefits offered by LiFePO4 batteries.
For users who mow their lawn often, LiFePO4 battery operated mowers are the best choice. That’s because these batteries last longer per session, but also offer more than double the charge rotations compared to lithium-ion battery operated mowers.
Which Battery Type is More Environmentally Friendly?
A LiFePO4 battery is considered more environmentally friendly for three main reasons:
- They are manufactured with fewer toxic or unsafe materials and chemicals.
- They charge quicker, offering a longer power output for the amount of electricity needed for a full charge.
- They last longer, lowering their replacement frequency.
How do Temperature Extremes Affect These Batteries?
Extreme cold or hot temperatures will always affect batteries of any kind. LiFePO4 batteries tend to handle extreme temperatures better than lithium-ion batteries, whether cold or hot. This makes LiFePO4 batteries ideal for high power machines like battery operated lawn mowers, leaf blowers, and hedge trimmers.
| Factor | Li-ion Battery | LiFePO₄ Battery |
|---|---|---|
| Cold Temperatures (less than 0 °C) | Performance drops significantly, reduced capacity, may stop working at around −10 °C | Better cold tolerance, works down to −20 °C but with some reduced capacity |
| Hot Temperatures (greater than 45 °C) | Prone to overheating, risk of thermal runaway (fire hazard), degrades faster | More heat-resistant, remains stable up to 60 °C, lower risk of overheating |
| Longevity in Extreme Temperatures | Shorter lifespan due to faster degradation in heat and inefficiency in cold | Longer lifespan, better stability in both high and low temperatures |
| Range | 0 to 45 °C | 20 to 60 °C |
When it comes to powering electric lawnmowers, not all batteries are created equal. While standard lithium-ion packs a punch, Mowrator’s remote-control lawnmowers run on rugged LiFePO4 batteries — built for durability, safety, and long-lasting performance. Say goodbye to unexpected battery failures and hello to a mower that’s always ready to roll. Explore Mowrator’s line-up today!
Lithium-Ion vs LiFePO4 in Electric Lawn Mowers FAQs
Can I replace my lawnmower's Li-ion battery with a LiFePO4 battery?
Yes, you can replace a lithium-ion battery with a LiFePO4 battery in your electric lawn mower. However, you must consider the voltage difference of your lawn mower. Lithium-ion powered mowers put out a voltage of 3.6V per cell, which is higher than LiFePO4 machines.
You’ll also need to make sure a LiFePO4 battery can be fitted to your mower before buying the new battery. Other compatibility challenges may exist, so consult your mower supplier before spending money on a new battery.
Which battery type charges faster?
LiFePO4 batteries charge an average of two hours faster than lithium-ion batteries. This decrease in charge time in no way affects the power output or length of use of LiFePO4 batteries. In fact, they boast better performance qualities despite their shorter charging time.
How do the life cycles of Lithium-ion and LiFePO4 batteries compare?
The life cycle of a lithium-ion battery is around 500 to 1,000 recharges. The life cycle of LiFePO4 batteries is around 3,000 to 5,000. These numbers may vary depending on the size of the batteries, what they are used for, and how well they are maintained.
