Compared to the old version, the DCU105B lithium battery is more compact and light weight, which is very advantageous for space-limited scenario. With a compact height of only 19cm specifically designed for underseat battery in caravan, or motorhome, DCU105B facilitates easier handling and installation, its compact size ensures efficient space utilization, making it the preferred choice for applications with limited space. It can provide high energy density while reducing overall weight. One of our customers who purchased pre- and post-improvement products reviewed that, “The battery is more compact and lighter than the 1st generation product. I have purchased other brands of batteries for sale before, but the Li+AGE optimized DCU105B is more popular with our customer, allowing customers to respond more flexibly to a variety of application needs. Li+AGE brand products offer excellent value for money. Compared to other major brands such as Super B, or Battle Born's 12V 100Ah, DCU105B does not fall short in terms of quality, functionality, and other aspects. Moreover, the price is affordable and within our budget. If you're concerned about the quality and the price, this is a great way to go.” The optimization of our products is a process that takes time and effort. We are committed to constantly seeking improvement and innovation to provide an even better product experience to our customers. Our customers' comments are also an affirmation and encouragement of these efforts, showing that they have felt the benefits of our product optimization.
Compared with other lithium batteries on the market, DCU105B lithium batteries have advantages in structure. It is a special design and manufacturing process that locks it between the shell and the various internal plates by screws, which can provide better structural stability and protection. The non-sealed mold design of the DCU105B allows for individual maintenance and repair of defective modules, eliminating the need to replace the entire battery pack. This not only reduces costs but also promotes sustainability. “To a high quality lithium battery system, we deeply understand electronics is the soul and mechanics is the skeleton. Every battery model in our list is proper designed to meet UL1973:2013 and IEC62619:2017 criteria, whether in mechanics or electronics. If you explore our battery mechanics, and you will find we use customized cell bracket and metal structures to fix the cell module, BMS with battery box to meet criteria of heat dissipation and vibration resistance.” Our senior engineer Mr. Zhou said.
