Rv lithium battery should be how to choose?

Rv when the choose and buy a lot of people, often have many problems, such as: engine, ok? Interior? Lithium battery big and so on, in fact, these are all the choose and buy more concern of the trailer. We all know that rv related to ordinary cars is much expensive, so choose a suitable for his own family saloon car is very important! When the choose and buy our saloon car, however, often there will be some misunderstanding, just like many friends when choosing rv often choose larger lithium battery, think big rv, lithium-ion batteries, very convenient, but big lithium battery really so good? Then to discuss the problem with us. 1, rv with lithium battery, the necessity of travel, the biggest problem is still the water and electricity, water problem is relatively good, water is not so trouble, more headaches is a supplement to the electricity. Some people say that travel saloon car, match is not portable generator power at any time? Generator compared to the point that the noise, the generator has good during the day, at night, if still use generators, accompanying the drives to go away from you, of course, a saloon car to walk alone, you don't want to how to use a generator, because the noise loud only yourself. And generator is more trouble, used every time on the way, when you need to have connection, but also to the slightly a bit further, down a little bit noise. If the rv, equipped with a certain amount of lithium batteries will be relatively good many. Li-ion battery and inverter, is almost no sound, and the feeling of home is the same. 2, rv with how much capacity lithium battery is suitable with how much capacity of the battery, mainly to see the car power and total power. General saloon on the rice cooker, electric water heater, The boiling water) , lighting, TV, audio equipment, etc. , some car with air conditioning. Don't usually with air conditioning of the rv recommended battery capacity with 400 ah, if car with air conditioning, recommended battery capacity not less than 400 ah, generally with ah - 600 800 ah. The above battery capacity for battery voltage of 12 v. 3, rv lithium battery selection and discern we often say that the lithium battery including the ternary lithium battery and lithium iron phosphate batteries, the excellency of ternary lithium battery is power density, low prices higher than the lithium iron phosphate batteries. But the ternary lithium batteries have two problems, one is the power attenuation fast, three years dropped 30% 50%, let's use the cell phone battery is this, 3 years or so, the cell phone battery have to be changed, or cell phone daily operation, had not been able one day. The second is the security of the ternary lithium batteries as iron phosphate lithium battery. In the collision, the external force, piercing, ternary lithium battery easy to fire, explosion and lithium iron phosphate battery, there is no this problem. If use lithium iron phosphate batteries, how do you know the battery good or bad? There is a simple solution, is the power density discriminance. Who is the same power battery, light weight, light is good, the heavier the owe better, secondary battery has, perhaps, is the poor quality of the battery or the battery itself. Now good quality lithium iron phosphate battery density can be 130 above, general at around 100.
