LiFePO4 Battery For RV Instead Of Lead Acid

Nowadays, there are very cheap and very expensive lithium batteries available online, and all of them claim to be the best. So how should ordinary consumers choose? Which is better for storing energy in a RV, lead-acid batteries or lithium batteries? And what voltage should be used, 12V, 24V, or 48V Battery?More and more people are getting into RVing nowadays. Many RV owners are considering adding their own energy storage systems due to cost considerations and varying power usage habits. These RV owners are also starting to encounter more and more confusion regarding which type of battery to use.

1. How to choose the battery type?

Currently, the most commonly used types of energy storage batteries are gel batteries (lead-acid batteries) and lithium batteries. The most popular lithium battery for energy storage is the LiFePO4 Battery. I still recommend that everyone choose the LiFePO4 Battery as it surpasses the lead-acid battery in terms of energy density, service life, depth of discharge, and usage cost. Typically, the LiFePO4 Battery can reach a depth of discharge of 80% and a cycle life of over 4,000 times. If charged and discharged once a day, it can last for 10 years. The lead-acid battery, on the other hand, has a depth of discharge of only 40% and a cycle life of only around 1,400 times, which means that it can last for only 3 years if charged and discharged once a day. Additionally, lithium batteries are noticeably smaller and lighter than lead-acid batteries. For those interested, there is a video where I discuss the comparison between sodium-ion batteries and lithium batteries, which is quite intuitive. To achieve the same actual electricity usage effect, the cost of lead-acid batteries is about two-thirds that of LiFePO4 batteries, and the full life-cycle usage cost is about three times that of LiFePO4 batteries. If you plan to use the battery for a short time and want to keep initial costs low, you can consider lead-acid batteries.

2. Which battery voltage should be chosen in LiFePO4 Battery?

I suggest choosing 48V Battery directly. Nowadays, power usage is getting higher and higher. If the voltage is too low, it will directly cause the current to be too high. Even a slight increase in the resistance value of the wire and the connecting terminal will result in a significant drop in voltage, causing the inverter to sound an alarm. Even if there is no alarm, the efficiency will be very low. In some cases, high temperatures can cause fires. If you want to achieve the same effect, the cost of a 48V battery is not higher than that of a 12V battery. The potential problems and risks are also greatly reduced. Perhaps some friends may ask, can I use a higher voltage? For example, 72V Battery? Yes, some people are now doing this. However, for voltages of 72V Battery and above, the matching products are very few and far between. It is very personalized, and once there is a problem, it is difficult to find a replacement, and the cost is relatively high, because there are few people doing this. Additionally, when the voltage is higher, attention should be paid to DC arcing, which can easily cause fires. I have a few videos discussing DC arcing for those interested.

3. How to identify the quality of LiFePO4 battery?

The most headache-inducing problem is here. Nowadays, the prices of LiFePO4 batteries vary greatly, with some selling for 1000 yuan per kilowatt-hour and others selling for 3000 yuan or even more expensive. How can we identify the quality of these batteries? Recently, many friends also want to build their own energy storage systems, but when they ask about the battery prices, they also find them expensive and want to use cheaper ones. Here, let’s introduce the current market situation. The price of lithium batteries has skyrocketed, and the price of a battery cell can increase by 40% in a month. Even if you have money, you can’t get the goods easily. You have to pay the full amount to the battery cell factory and wait in line. Friends who invest in lithium battery stocks should be very clear about the situation. The global demand for carbon neutrality has created a huge demand, which is difficult to alleviate in the short term. Now, whenever a new type of battery comes out, it will become explosive news, such as aluminum batteries. Even the used batteries stripped from scrapped electric vehicles cost at least 800 yuan per kilowatt-hour. If they are brand new, they usually cost more than 1200 yuan/kWh. Companies like CATL and BYD charge astronomical prices. Don’t even mention Tesla’s low procurement cost. They really don’t want to deal with such small quantities. And this is just the battery cell. The cost of turning it into a usable pack is even higher. When buying batteries, it is advisable to look for reputable brands and reliable channels and purchase at a reasonable price. The biggest fear for lithium batteries is internal short circuits during use, which can cause them to burn instantly. Using inferior or problematic battery cells to build an energy storage system poses a very high risk.
