This paper introduces the battery usage and matters needing attention in off-road towed room

RV riders currently use lead-acid batteries. Lithium batteries have gradually entered the RV camping market, among them, the off-road trailer RV used lithium iron phosphate because of its high energy density, long life, environmental protection and safety performance of the advantages of high, in recent years in many fields to replace the traditional lead-acid batteries. Lithium-iron phosphate battery has been widely used in municipal new energy buses, new energy vehicles, communication base stations and computer rooms and other fields.

In the selection of batteries, safety, service life, charge and discharge performance, volume and weight of the four major factors are an important consideration for car companies and car friends.

The advantages of lead-acid batteries used in off-road trailers: mature technology and cheap price;

Disadvantages: small storage capacity, large weight, can not deep discharge, relatively short life, lead-acid colloidal battery needs regular liquid supplement, power loss will greatly reduce the service life.

Lithium battery advantages: belongs to the new technology in the field of battery, because of its environmental protection characteristics and technical stability, the state strongly support the development, large storage capacity, light weight, can be deep discharge, relatively long life; Disadvantages: Must have a reliable BMS solution to ensure security and high cost. Safety is the first important Angle to choose the battery. In particular, all kinds of battery accident news frequently, so that the majority of car friends are also "talk about lithium color change".
