It automatically activates heating when charging below 32°F (0°C), and stops heating once the temperature exceeds 41°F (5°C) to resume normal charging—protecting battery health and boosting charging efficiency. With a low-temperature discharge cut-off at -20℃ ± 4°C (-4°F ± 7.2°F), it ensures safe, consistent power output even in extreme cold, eliminating cold-weather charging and usage worries.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0718\/4574\/0839\/files\/Temgo_12V_300Ah_self-heating_lithium_battery_for_any_climates_desktop.webp?v=1786514553\" alt=\"Temgo 12V 300Ah self lithium battery for any climates\" class=\"desktop--device\" width=\"1464\" height=\"600\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cimg alt=\"Temgo 12V 300Ah self lithium battery for any climates\" class=\"mobile--device\" width=\"350\" height=\"263\" loading=\"lazy\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0718\/4574\/0839\/files\/Temgo_12V_300Ah_self-heating_lithium_battery_for_any_climates_mobile.webp?v=1786514880\"\u003e\u003c\/p\u003e\n\u003ch2\u003e\n\u003cmeta charset=\"utf-8\"\u003e \u003cspan\u003e\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003cspan\u003eClear Metrics, Effortless Monitoring\u003c\/span\u003e\n\u003c\/h2\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cspan\u003e\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003cspan\u003eCheck remaining energy via the TEMGO App before operating power-hungry devices or planning overnight power consumption.
