How to use electricity for RVs is a very important and difficult to solve perfectly. No matter what coup you have, the core of the RV power supply system must be the battery.

What is the most common type of battery in a motorhome? It should be the old lead-acid battery. The performance of the lead-acid battery is too poor, in fact, it is not suitable for use in the motorhome. I wrote a piece of tofu earlier, and you are welcome to read it:
Interestingly talk about the grievances between RVs and batteries: how can they not be separated from the lead-acid battery of marriage
Now, more and more RVs use lithium batteries.
We know that there are several types of lithium batteries. Common ones are lithium iron phosphate batteries, ternary lithium batteries, and lithium titanate batteries.

Examining the characteristics of these types of lithium batteries, it can be said that each has its own merits. But to say that the most suitable for use in RVs, it is none other than lithium titanate.
Lithium titanate has several characteristics that make people have to love:

1. Security
The safety of lithium batteries has always been a concern for everyone, and spontaneous combustion accidents have always been a dark cloud shrouded in the electric vehicle industry.
As a modified car, the manufacturer must be a "generalist" in many aspects to complete the modification of the RV. "Generalist" also means that they are definitely not "professionals." Tuning factories cannot have deep knowledge in circuits.
Therefore, the safety hazards of using lithium batteries in RVs will be greater. RV spontaneous combustion accidents have been reported in the news, and many of these accidents are caused by overheating of lithium batteries. Many high-end RVs also insist on using lead-acid batteries, obviously not for cost considerations, but to ensure the safety of the entire vehicle.
Among several lithium batteries, lithium titanate is the safest. It will not smoke, catch fire, or explode during acupuncture, squeeze, and short-circuit, and its safety is almost comparable to that of lead-acid batteries.

2. Support fast charge
A general electric car requires several hours to charge (even up to 10 hours during slow charging), which greatly reduces the convenience of the car.
However, lithium titanate can be charged extremely quickly due to its unique principle. If conditions are met, it can be filled within ten minutes. Those buses that use lithium titanate can be fully charged during the driver's shift.

3. Super long life
The cycle life of an ordinary lithium battery is about 3000 times. If it is used frequently, it can be used for about 5 years. Of course, the technology of lithium batteries is also improving, and the life of new batteries will gradually increase.
However, no matter how it is improved, it cannot be compared with lithium titanate batteries. The cycle times of lithium titanate batteries can reach more than 30,000 times, and the service life can reach 30 years. Save a little bit, it can simply be left to your next generation to use as an "ancestral" object.
This is not just a theoretical calculation. Some wind power plants in the United States have actually verified the ultra-long life of lithium titanate batteries.
It can be said that if the RV is replaced with a lithium titanate battery, there is no need to replace the battery for life.

4. Adapt to a wide temperature range
This winter, electric car users in the north are complaining about the problem of low temperature power loss. In the Northeast, electric vehicles are basically unusable in winter.
However, those buses in northern cities that use lithium titanate batteries can still run in the cold winter. Lithium titanate batteries can work normally in the range of minus 50 degrees to 60 degrees above zero, with little change in power.
For RVs, the impact is not that big, after all, a large number of RVs move south in winter. However, many RVs still have to face various natural environments (such as entering Tibet and Xinjiang). The wide temperature-resistant lithium titanate will give us a lot of peace of mind.
Just talking about the advantages is not objective. If the whole body is good, lithium titanate has long been popular, but the fact is obviously not.

Disadvantages of lithium titanate
A major disadvantage of lithium titanate batteries is the low energy density, that is, lithium titanate batteries of the same volume and weight have less power storage than ternary lithium batteries and lithium iron phosphate batteries. The biggest reason why automobile manufacturers face the many advantages of lithium titanate and still discard it. Imagine the electric car you are fancy. If the cruising range is reduced from 500 kilometers to 250 kilometers, would you still buy it?

Lithium titanate is too suitable for motorhomes. It has many advantages and disadvantages, but the price is too high. In contrast, lithium iron phosphate batteries can be described as high quality and low price. The battery life of lithium iron phosphate is strong, and the cost is much lower than that of lithium titanate, which greatly reduces the cost of choosing lithium titanate batteries.
