Traditional passive balancing circuits found on standard BMS boards simply burn off excess voltage as heat using resistors—a slow and highly inefficient process. The ETA3000 revolutionizes this by using an inductive buck-boost topology to actively transfer energy from the higher-voltage cell directly into the lower-voltage cell, dramatically reducing heat generation and wasted energy.\u003c\/p\u003e\n\u003cp\u003eDesigned specifically for 2S battery configurations (and easily cascadeable for 3S, 4S, and beyond), this IC can deliver a massive balancing current of up to 2A depending on the external inductor used. This ensures extremely fast voltage equalization, which is critical for high-drain applications like FPV drone batteries, power tools, and custom power banks. Housed in a tiny 2x2mm DFN-8 package, it requires minimal external components, allowing you to design ultra-compact, high-efficiency battery management systems.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKey Features:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eActive Inductive Balancing:\u003c\/b\u003e Transfers energy between cells rather than dissipating it as heat, offering significantly higher efficiency than traditional passive balancers.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eHigh Balancing Current:\u003c\/b\u003e Capable of up to 2A balancing current, quickly equalizing cell voltages even in large-capacity battery packs.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eUniversal Chemistry:\u003c\/b\u003e Works flawlessly with both standard Lithium-Ion\/LiPo (4.2V) and LiFePO4 (3.6V) battery chemistries.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eUltra-Compact Footprint:\u003c\/b\u003e The microscopic 2x2mm DFN-8 package saves highly valuable PCB space on custom BMS boards.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eSpecifications:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePart Number:\u003c\/b\u003e ETA3000D2I\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eIC Type:\u003c\/b\u003e Inductive Active Battery Balancer\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eSupported Cells:\u003c\/b\u003e 2S (Cascadeable for multi-cell packs)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eMax Balancing Current:\u003c\/b\u003e Up to 2A\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eStandby Current:\u003c\/b\u003e ~2µA\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePackage Type:\u003c\/b\u003e DFN-8 (2x2 mm, 0.5mm pitch, SMD)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RC-LIFE","offers":[{"title":"Default Title","offer_id":54285567099218,"sku":null,"price":2.0,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1065\/8067\/2850\/files\/images_5b47c7f7-823a-4a60-9bd7-79be68b7b8d2.jpg?v=1786959231","url":"https:\/\/rc-life.com\/pl\/products\/eta3000d2i-2a-inductive-active-battery-balancer-2s-li-ion-lifepo4-dfn-8","provider":"rc-life","version":"1.0","type":"link"}
