Why don’t RV refitting factories like to install lithium batteries? In order to avoid misunderstandings about the modification industry, we still have to break this matter apart and break it down into several points!
1. There are security issues. Although few people have actually seen a lithium battery catch fire, this thing has been passed around like this. Since there is a one in ten thousand possibility, why take the risk? Making a RV is not a one-off deal, and you can’t leave it alone after leaving the factory. Since it involves after-sales, why should you set yourself up for it!
2. Stability issues. Lead-acid batteries are more stable than lithium batteries. A mature product that has been around for more than 100 years is still used in cars now! In addition, the lithium battery loss is greater at sub-zero temperatures! Is it not allowed to use it when the weather is cold? In fact, lead-acid also has this problem, but it is not as serious as lithium battery. This problem can be solved by creating a constant temperature environment.
3. The cost issue, in fact, this has nothing to do with the manufacturer. The wool comes from the sheep. If you choose lithium batteries, the price will naturally increase. But for users, this is the case. Obviously, a 200,000 chassis, how can you choose and match a few things, and the cost will be 400,000? From this perspective, it is understandable to try to help users reduce costs, reduce material budgets, and avoid running orders .
4. Technical issues. Due to the mature application of lead-acid batteries, hydropower engineers from many large factories can easily modify them according to user needs. But now users are using 48V and lithium batteries. As a last resort, these masters who have worked on 12V for half their lives have to continue learning. Although it seems to users that it is a matter of adding two modules, it has actually broken the original system they are familiar with …
In short, there are too many reasons for refitting factories not to choose lithium batteries!
But it has been much better recently. Before 2018, many RV refit manufacturers vowed not to use lithium batteries. Didn’t you compromise with the market in the end? Although it may not be a good thing in my opinion. But the current solution is actually relatively safe.
In addition, users can also choose to bring their own battery packs, such as those used in base stations. In theory, as long as there is no problem with the wiring, there will be no problems with the battery pack when it goes on the market. The only problem is that you bring it yourself, the modification factory will not guarantee it for you!
It seems that now there are lithium batteries for RVs, and they have started to provide insurance! Although this is a dumb decision, on the other hand, it also proves that the product is trustworthy, and the insurance company is not stupid…
Lithium batteries are optional, used for base stations, disassembled by BYD, Ningde…but the premise is that the user must understand electricity. If you’re an electric noob like me, don’t bother.
The most important point is actually what I just said, the cost, comrade! A sufficient set of lithium battery + inverter costs 20,000 to 30,000 yuan. At the same price, there is still room for a lead-acid + silent generator… If you are not short of money, of course it is a lithium battery 800AH + 3000W inverter + solar shop The most reliable RV generators with over RMB 20,000!
There should be no refitting factory that does not install lithium batteries at all, right? It’s just not recommended!
Simple analysis of the first RV may not be accurate, welcome to discuss.
