It supports Li-ion, NiMH, and NiCd packs, with four independent channels that can be programmed individually or run together. This flexibility helps you streamline testing, conditioning, and charging tasks without juggling multiple devices.\u003c\/p\u003e\n\n\u003ch2\u003eWhat you can do\u003c\/h2\u003e\n\u003cp\u003eEach channel handles charging, discharging, conditioning, or analysis, and you can operate all four in unison or separately to fit your workflow. Notable operating modes include five per channel: Charge, Discharge, Discharge Refresh, Charge Test, and Quick Test. Negative delta V detection aids NiMH and NiCd packs during full charge, while Li-ion cells follow a CC\/CV charging profile for safe and controlled conditioning.\u003c\/p\u003e\n\n\u003ch3\u003eKey capabilities\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eIndependent channels with per channel programmability\u003c\/li\u003e\n  \u003cli\u003eCharge, discharge, condition, or analyze up to four batteries at once\u003c\/li\u003e\n  \u003cli\u003eAdjustable charging rates from 200 to 2000 mA per channel\u003c\/li\u003e\n  \u003cli\u003eMaximum 2000 mA total charge current; up to 1000 mA discharge current\u003c\/li\u003e\n  \u003cli\u003eBacklit LCD displays capacity, voltage, time elapsed, and current for quick at-a-glance readings\u003c\/li\u003e\n  \u003cli\u003eSupports NiMH NiCd and a wide range of Li-ion cell sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhy this matters in real life\u003c\/h2\u003e\n\u003cp\u003eWhether you’re stocking a workshop, maintaining a hobbyist battery collection, or testing batches of cells, the BT-C3400 offers visibility and control. It covers NiMH\/NiCd sizes from AAAA through SubC and a broad set of Li-ion formats, including common sizes like 10440, 14500, 18650, and more. The result is a versatile tool that helps you assess readiness and performance without guessing.\u003c\/p\u003e\n\n\u003ch3\u003ePower, compatibility, and extras\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eAC input: 100 240 VAC, 50 60 Hz\u003c\/li\u003e\n  \u003cli\u003eAdapter output: 12 V DC, 3.0 A\u003c\/li\u003e\n  \u003cli\u003eMaximum charging capacity: up to 20,000 mAh\u003c\/li\u003e\n  \u003cli\u003eOperating temperature: 0 to 40 C\u003c\/li\u003e\n  \u003cli\u003eIncludes: C3400 charger, wall adapter, car adapter, and operating manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eDesign and usability\u003c\/h2\u003e\n\u003cp\u003eThe backlit LCD keeps information legible in dim environments, while the four channel layout helps you stay organized during long sessions. This makes it practical for both individual use and small operations where multiple batteries are handled quickly and safely. While the BT-C3400 provides powerful testing and conditioning capabilities, outcomes will vary with battery history and condition, so approach results as informative rather than guaranteed outcomes.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What battery types and sizes does the Opus BT-C3400 support?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: The unit handles Li-ion, NiMH, and NiCd cells across common sizes, with up to four channels for simultaneous testing.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What makes the BT-C3400 useful for battery maintenance?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It offers multiple modes per channel and a backlit LCD to read capacity, voltage, and time, enabling flexible charging and condition checks.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Opus","offers":[{"title":"Default Title","offer_id":47502124482734,"sku":"B07T941JCF","price":142.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0735\/6012\/9710\/files\/opus-bt-c3400-front-panel.jpg?v=1770972456","url":"https:\/\/handyskook.ca\/products\/opus-bt-c3400-4-channel-battery-charger-analyzer-for-li-ion-nimh-nicd-aa-aaa-c-18650","provider":"HandySkook","version":"1.0","type":"link"}
