It is a practical safeguard for 12V electrical systems used in cars, utes, 4WDs, caravans, RVs, trailers, boats and workshop battery setups.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/ae04.alicdn.com\/kf\/Hecdda13b21c4451da45df059a7a2eccbB.jpg\" alt=\"12V low voltage battery cut off controller front view\"\u003e\n\n\u003ch3\u003eAutomatic Cut-Off And Reconnect Function\u003c\/h3\u003e\n\u003cp\u003eWhen the battery voltage falls below the selected cut-off point, the controller disconnects the load to help reduce the risk of excessive battery discharge. Once the battery voltage rises back to the selected recovery value, the module can automatically reconnect the load, making it useful for auxiliary battery systems and general DC protection setups.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/ae04.alicdn.com\/kf\/Hc7ca8c802938415681cf6378a534ad21P.jpg\" alt=\"12V undervoltage controller display and buttons\"\u003e\n\n\u003ch3\u003eAdjustable Voltage Settings\u003c\/h3\u003e\n\u003cp\u003eThe controller allows both the turn-off voltage and turn-on voltage to be adjusted using the onboard buttons. With 0.1V control precision and a listed voltage error of ±0.1V, it gives users practical control over when their 12V system disconnects and reconnects based on battery condition.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/ae04.alicdn.com\/kf\/H880f83a707e24124944015aaed1ff3781.jpg\" alt=\"12V battery protection controller adjustment buttons\"\u003e\n\n\u003ch3\u003e20A Control Current For DC Loads\u003c\/h3\u003e\n\u003cp\u003eDesigned for 12V storage batteries and lithium batteries, this controller supports a control current of up to 20A. It is suitable for compatible DC loads where battery protection is needed, including lighting circuits, small accessories, low-voltage equipment and protected DIY electrical installations.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/ae04.alicdn.com\/kf\/Hd3de3c3b77f0455b8ad5e8da22644bdfz.jpg\" alt=\"12V low voltage cut off controller wiring and product detail\"\u003e\n\n\u003ch3\u003eLED Indicator For Battery Status\u003c\/h3\u003e\n\u003cp\u003eThe built-in LED indicator helps show when the battery is in an under-voltage condition, giving a clear visual reference during operation. This makes it easier to monitor system status in battery boxes, panels, 12V storage setups and accessory control circuits.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/ae04.alicdn.com\/kf\/Hd3e726906eba4907b26da7fb4f1c0239f.jpg\" alt=\"12V battery undervoltage controller LED indicator\"\u003e\n\n\u003ch3\u003eCompact And Lightweight Installation\u003c\/h3\u003e\n\u003cp\u003eThe controller has a compact body size of approximately 8cm x 4.3cm x 2.8cm and weighs around 40g, making it easy to position inside a protected 12V electrical setup. It is well suited to enclosed installations where space is limited, such as caravan panels, auxiliary battery boxes, vehicle accessory systems and workshop DC projects.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/ae04.alicdn.com\/kf\/Hb35cdd59146d46cd9d53106b84a9ea03f.jpg\" alt=\"Compact 12V low voltage battery cut off switch controller\"\u003e\n\n\u003ch3\u003eSimple Reset And Practical Use\u003c\/h3\u003e\n\u003cp\u003eThe controller includes a factory reset function by holding the S1 and S2 buttons until the display shows 888. Each package includes one battery under-voltage controller, ready to be wired into a compatible 12V DC system. Correct wiring, current limits and battery compatibility should always be checked before installation.\u003c\/p\u003e","brand":"Tuck's Performance ","offers":[{"title":"Default Title","offer_id":52079132541229,"sku":"\u003cnone\u003e","price":20.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/7594\/7821\/files\/Hecdda13b21c4451da45df059a7a2eccbB_155b3aff-84aa-4343-a096-fa1e925f1e74.webp?v=1779401540","url":"https:\/\/tucksperformance.com.au\/products\/12v-low-voltage-battery-cut-off-controller","provider":"Tuck's Performance ","version":"1.0","type":"link"}
