Why should we upgrade to lithium battery now?

I know that some people may not be sure if they are ready or need a battery upgrade. No matter the cost is one of the reasons, or there are other reasons that you may not find the need to upgrade. If I were you, I would like you to consider other factors.

LFP batteries are safe - people have been paying attention to the safety of lithium batteries for a long time. A small part of the news reported that the lithium battery pack was on fire. Indeed, this is a risk, and the FAA has even imposed restrictions on the amount of batteries it is allowed to carry. It doesn't really depend on the chemical nature of the lithium battery. In particular, LiFePO4 batteries have been proved to have the minimum risk of ignition. With the help of appropriate assembly technology, LiFePO4 batteries with BMS protection generally have no probability of ignition.

LFP batteries are lightweight – lithium batteries have a much higher energy density than lead-acid batteries. For the same amount of available energy, LiFePO4 battery is only one third of the weight of lead acid. You will benefit from the light weight of lithium batteries, lighter vehicles and better fuel economy, or up to four times the power of lead-acid batteries at the same weight. Because LFP battery is very light, if you want to have more power, upgrading the standby power supply to lithium battery is the most convenient way.

LFP batteries will power your RV longer – In lead-acid batteries, the recommended DOD (depth of discharge) does not exceed 50% of its rated capacity. When the periodic discharge exceeds 50%, the battery will degenerate and lose its charging ability soon. In contrast, LFP battery can discharge more without any harm. The experiment shows that 80% DOD of LFP battery can cycle more than 3500 times. In order to extend the service life of lithium battery to the greatest extent, it is recommended to charge it to no more than 90% and discharge it to no less than 10%. This means you will get about 80% of the battery capacity rating. This also means that you can use LiFePO4 batteries to run the RV over 60% at exactly the same rated capacity as the AGM. So more and more people are willing to use lithium batteries in campers to make their RV travel more convenient and comfortable.

LFP batteries will last for a long time – one of the biggest benefits of upgrading to lithium batteries is how many charging cycles they can withstand without significant capacity degradation. If high-quality AGM batteries (about 500 cycles) are used, the fully charged and discharged AGM batteries can be used frequently every day, even for 2 years, and can no longer be used directly. In contrast, LiFePO4 may be cycled 4000 to 5000 times. This is equivalent to 10 times longer life. It may be dramatic that you may not even keep the campers that long.

LFP battery has less voltage sag under load, so it's better for your components - another advantage of lithium battery chemistry is that the discharge curve is not as linear as lead-acid. This means that you will be able to maintain a more constant voltage throughout the charging process without excessive voltage sags. Why do you say that? Well, it's important that sensitive electronic devices using DC power from batteries have enough power to prevent damage. In lead-acid batteries, heavy loads can cause a sharp drop in voltage. This is not obvious in lithium batteries, so your electronic products and other electrical appliances will be more durable, and the service time will be significantly improved.
