Lithium RV battery is a rechargeable 12V battery, whose chemical composition is different from that of standard lead acid 12V battery. Many motorhomes have been upgraded to these, especially those that use solar energy to charge household batteries.
Lithium battery is more environmentally friendly than lead acid. Many companies that produce these products also attach great importance to sustainability

Types Of RV Battery?
Lithium batteries and lead-acid batteries are the most common types of batteries. You can find them when looking for the best deal. Let’s look at the advantages and disadvantages of each method.
Sealed Lead Acid Battery
Sealed lead-acid battery is the traditional battery power supply in the market. Most RVs use lead-acid batteries. When your RV battery runs out, you have to jump, you jump is lead-acid battery.
Your RVs is not the only application that uses lead-acid batteries; They are standard for many types of motors. Using traditional batteries has some advantages, but for many applications, they are outdated. Let’s take a closer look.
Lead-acid batteries have also existed for decades and are also an affordable option. You are likely to replace a lead-acid RV battery at a price of less than $200, so even if you replace it every few years, it is good to have a low upfront cost.
It should be noted that sealed lead-acid batteries are not as dangerous as unsealed lead-acid batteries. When the battery is properly sealed, you don’t have to worry about acid and harmful chemicals leaking into the environment.
The bad news about lead-acid batteries is that they are relatively heavy. You can still use the heavy battery to drive the streamer motor, but because of the increased weight, your RV’s speed in the water will be reduced.
More importantly, you can only discharge about half of the lead-acid battery before losing power efficiency. In addition, every time you release them below 50%, they will be injured. The damaged battery will not only run out faster, but also have a shorter life. You can learn more about the difference between lead acid and lithium here.
When you charge them, they are difficult to reach the capacity. They have several charging cycles, including a floating charging cycle that takes longer and uses more power.
It should be noted that you can only use sealed lead-acid batteries on the RVs, but not unsealed batteries. The instability of water will cause acid to overflow from unsealed batteries, pollute the environment and may cause physical injury.
Lithium battery is the most advanced battery type. In many applications, lithium battery is replacing lead-acid battery. These batteries move from the negative electrode to the positive electrode in a cycle during charging, and then return to the negative electrode. Because of their unique charging cycle, they charge faster and can provide consistent power from full to full.
First of all, lithium-ion batteries are light and very suitable for RVs. You will enjoy a more balanced ride with much less resistance. Their light weight also helps to improve efficiency, so their amperage often lasts longer than lead-acid batteries.
They also charge faster. You expect to be fully charged in a few hours instead of waiting all day and all night. They do not need floating charging stage, so the charging speed is more stable.
Most importantly, you can completely release them without damaging their life span. You do not have to closely monitor the battery life to prevent it from falling below 50%. Our battery can discharge 100% and then turn off automatically to prevent any damage to the battery. It is still important to pay attention to the battery power, so that you will not be trapped in the water because the battery power is exhausted. But at least you don’t have to buy new batteries because of excessive discharge.
You can also expect that the amperage consumption of lithium battery will be more stable, because the voltage will not drop too much. It is easier to predict the battery life because the ampere consumption will not fluctuate too much. When the lithium battery is low, the power of the motor will not decrease; The power is stable from full to empty.
One of the best benefits of lithium batteries is that they can be used for 10 years or more, and usually have a 10-year warranty period. Our lithium battery can be used for 15 years or more with proper care, which is not uncommon.
In addition, because you do not have to replace the battery for at least 10 years, you can save money compared with the number of lead-acid batteries you must purchase in the same period of time.
The most important “disadvantage” of lithium batteries is that they are expensive in the early stage. They usually cost hundreds of dollars, while traditional lead-acid batteries cost less than 200 dollars.
At first, the cost can be reduced, but when your battery has been used for more than 10 years, you will realize that buying only one battery saves time, money and trouble compared with three or four lead-acid batteries in the same time period.
What is the price of lithium battery for RV?
The typical price of a 100-ampere-hour, 12 volt lithium battery for an RV hovered around $1000 for a long time. However, you can now find many options in the range of $700 to $900.
When comparing the price of lead-acid batteries, this sounds very similar. But remember, even when comparing batteries with the same capacity, lithium batteries have longer life and more usable energy.
For example, a 100-ampere-hour lead-acid battery can only use 50% of its capacity before it begins to suffer irreparable damage. You can completely discharge the LiFePO4 battery without damage.
How to charge RV battery?
The actual process of charging is not difficult. For portable or on-board chargers, the charging process is almost the same.
1. First unplug the motor plug. Check the battery for leakage or damage and ensure that the battery terminals are clean.
2. Connect the charger to the battery. Red turns red, then black turns black. When finished, you will perform this operation in reverse order. If you want to use a battery pack to charge multiple batteries, do the same.
3. Connect the charger to the power supply. After connecting, open it.
4. Monitor the progress. Some chargers will tell you how long you have, while others will not. Pay attention to overcharging or overheating. Do not leave the battery unattended for a long time.
What is the best RV battery?
Obviously, lithium battery is the best for the following reasons.
Extremely light – For boats and boats whose weight may be an important factor, lithium batteries are 50% lighter than traditional batteries on average.
Significantly prolong battery life – lithium battery life is up to 10 years, while the average life of lead-acid wet battery and AGM battery is 2-4 years.
Although the upfront cost of lithium batteries is high, they can save you money in the long run. If you calculate the cost of replacing the battery every 2-3 years instead of replacing a lithium battery every 10 years, you will probably spend less on the battery.
100% discharge depth – this basically means that you will have full power regardless of the charging level. Traditional lead-acid batteries often lose charge and capacity when they are exhausted.
Higher power – due to the continuous and sudden fluctuation of speed, the streamer motor needs considerable starting torque (also known as thrust). When fast acceleration is required, lithium batteries can provide more energy because their voltage drop can be ignored.
Smaller size: lithium-ion batteries are not only lighter, but also occupy less space.
Based on the above advantages, it is obvious that lithium battery is the best power battery
How Long Does A RV Battery Last?
There is no real hard and fast rule on how long your RVs battery can last. There are many variables that can affect this. The size and type of battery need to be considered. Whether you have a trickle charger or not.
Now, in terms of overall life, we have variables. A good battery can last at least five to seven years. Rechargeable batteries can only handle so much charge before the power drops too low. No matter what happens, the capacity of the battery will inevitably lose over time. As time goes on, even the best battery cannot provide power in a proper way. But battery technology is improving. A good deep-cycle battery should be used for several years under proper maintenance
