industrial applications. It adopts a dual independent power supply design, capable of simultaneously and independently charging two sets of 6 to 14 cell (6S-14S) lithium batteries (LiPo\/LiHV\/smart batteries) quickly, with a single channel maximum power of 1400W and a whole unit maximum power up to 2800W. Its core goal is to address the rapid charging and intelligent maintenance needs of high-capacity, multi-cell battery packs. It is widely used in fields with stringent requirements for power supply efficiency and reliability, such as drone aerial photography, fire rescue, agricultural plant protection, and surveying.\u003c\/p\u003e\n        \u003c\/section\u003e\n\n        \u003csection id=\"key-tech\"\u003e\n            \u003ch2\u003eCore Technology Advantages\u003c\/h2\u003e\n            \u003cdiv class=\"grid-container\"\u003e\n                \u003cdiv class=\"card\"\u003e\n                    \u003cdiv class=\"card-icon\"\u003e🔌\u003c\/div\u003e\n                    \u003ch3\u003eTrue Dual-Channel Independent System\u003c\/h3\u003e\n                    \u003cp\u003eInternally uses two completely independent 1400W power modules.
