Which is the Best for RVs?---LiFePO4
It is widely known that the RV has a long idle period and is utilized for long, bumpy outdoor travels. The RV’s battery powers the home appliances and serves as a storage device for the electricity produced by various sources. RVs therefore require a battery with a higher capacity and longer lifespan than regular electric vehicles.
RVs typically use lead-acid batteries as their power source. Although lead-acid batteries are inexpensive, they are bulky, heavy, and only have a limited lifespan. They might be a wise solution for RVs and persons with low electricity usage. You will require at least 10 pieces of 100Ah lead-acid batteries if you use 10 kWh daily. A 100Ah lead-acid battery typically weighs 30KG, which implies that 8 of them will total 240KG, or about the weight of 3 adults. Lead-acid batteries also have a short shelf life and their storage rate decreases over time, necessitating frequent battery replacement on the part of users.

Additionally, the BYD blade battery maintains LiFePO4’s outstanding level of safety while bringing its energy density very close to that of ternary. LiFePO4 batteries are utilized more and more frequently in the EV market thanks to benefits like low cost and great safety. Installation and production of LiFePO4 batteries are both increasing. LiFePO4 may be widely used in power storage and electric vehicles in the future, which is an obvious conclusion.
The Maxworld LiFePO4 battery has the following features:
- Intelligent Charge and Discharge Management: The tracking device carries out smart charge management so that can automatically monitor the charge and discharge state of the battery.
- 1C continuous discharge has good discharge rate characteristics and is suitable for high current discharge applications.
- Additional Maxworld LiFePO4 battery designs are based on the real-world RV use. After all, the simpler the better when we travel!
- Manual switch port with simple operation, automatic startup and storage, and additional features for RS485 communication

- Complete Intelligence: To accomplish remote management and cheap maintenance costs, a separate centralized monitoring module is used for remote communication. Make sure your journey goes smoothly.
How to Charge a LiFePO4 Lithium Battery for an RV
1.
The lithium charging methodology has undergone some significant changes as well. The three fundamental charging stages required to successfully charge a lead-acid battery are bulk, absorption, and float. Lead-acid also needs a balance and maintenance stage to prevent sulfation. Lithium, on the other hand, only requires two phases of charging: a quick absorption charge taking 10 to 15 minutes to add the remaining 3% SOC after a bulk charge to roughly 97 percent SOC. Since lithium does not sulfate, the additional float and balancing phases are not required.

But when it comes to charging, lithium has another important distinction: it’s customary to keep lithium topped-off or “trickle charged” at 100 percent SOC. Simply said, you shouldn’t do it. This is due to the possibility of lithium being “stressed” during storage due to variations in the ambient temperature. A lithium battery should actually be kept at its optimal state of charge (SOC), or around 13.1 volts, or between 40 and 80 percent of its maximum capacity. Lithium batteries have a modest monthly self-discharge rate of 1% to 2%, as opposed to lead-acid batteries, which experience “health” issues after receiving a partial charge or after being stored with a charge that is less than full. What’s the verdict then? Stop topping off your lithium batteries at home or in an RV park for extended periods of time; you’re probably damaging them.

The quantity of amperage has a significant influence on how rapidly a lithium battery recharges, just like it does with any rechargeable battery. As we have mentioned, lithium has a much higher potential charging rate than lead-acid. This is brought on by the decreased internal resistance of lithium. Lead-acid batteries can only be “bulk” charged at a rate of.3C, or 30% of their capacity, and must then undergo an absorption phase that may last even longer. In comparison, lithium batteries can be “bulk” charged at.8C, or 80% of their capacity. This was one of the factors that encouraged some owners of lithium batteries to install more powerful, larger AC battery chargers, like a 60 or 80 amp device. Additionally, it explains why so many homes have solar panels on the roofs.

The lithium battery needs a DC-to-DC charger for both smart and conventional alternator charging. The DC-DC charger provides the voltage and charging profile required for LiFePO4 charging in addition to dividing the vehicle battery from the camper house battery. The typical 10-AWG is too tiny to transmit a suitable charging voltage at the lengths used in truck campers and RVs. To obtain a proper charge, heavy-gauge wiring is necessary. An Anderson plug or a similar will also be needed to connect the camper to the truck. We suggest using a minimum 25A charge rate when building your circuit, however you can utilize a second alternator to get higher charge ratings.
Are You Ready to Switch to Lithium in Your Travel Trailer?
There aren’t many reasons not to replace a lead-acid RV travel trailer battery with a lithium battery. You can fix a lot of the issues with your present lead-acid batteries with this simple change!
Even though the upfront cost is a significant concern, consider it a hassle-free long-term investment. You can use your device for many more uninterrupted hours and for longer periods of time without worrying about how long your battery will last by converting from a single lead-acid battery to a single lithium battery.
