Applicable with 1S–4S lithium-ion battery connections, offering extensive compatibility 2. Offers battery percentage display for immediate readability 3. Ultra-compact design fits neatly in small devices 4. Consumes minimal power, prolonging device's standby time 5. Simple manual string count switch, providing ease of use KBAB0066-001\/KBAB0066-002 (variants with\/without buttons) Technical Data Maximum voltage handling: 36V±10 Voltage range: 3~17.29V Unlimited battery capacity Battery status representation: 0% to 100% Detection precision: ±1% Average current usage: 7mA±0.3mA Refresh rate: 0.3 seconds each instance No output management Lacks reverse polarity protection (Ensure terminals are connected correctly to prevent damage) Suitable battery range: Compatible with all 1~4 lithium-ion battery setups rated at 3.7V (full voltage at 4.2V), whether in series or parallel, including 14500, 18650, 21700, polymer lithium-ion types, and all capacities and sizes. Model with button feature Integrated smart buttons, immediately determines cell count on activation, preset to mode 0. Screen activates around 1 second after power-up, indicating current battery percentage. Short press (under 3 seconds) enables\/disables device, long press (over 3 seconds) transitions between modes to mode 1. Mode 1 by default keeps display off. A brief button press (under 3 seconds) awakens the screen, numbers rise from 0% to actual battery level in about 1 second (Button function sharing necessitates filter capacitor charge upon activation). Display turns off automatically after 3 seconds delay. Long press returns setting to mode 0, cycle repeats; KBAB0066-003 (Parallel 4.2V configuration) Specifications Maximum voltage endurance: 36V±10 Voltage window: 3~4.41V Battery capacity: Unrestricted Battery scale display: 0% to 100% Precision rate: ±0.25% Regular operating current: 7mA±0.3mA Frequency of update: 0.3-second intervals Absence of output control No reverse polarity protection (Incorrect terminal connection risks damage) Relevant battery scope: Caters to single lithium-ion cells or parallel arranged battery packs rated at 3.7V (full charge at 4.2V), covering 14500, 18650, 21700, polymer-li-ion types of any capacity\/size. The module exhibits battery percentage shortly after activation. Safety Notes: 1. VCC applies to positive terminal, GND to negative terminal.\u003c\/span\u003e\u003c\/p\u003e\u003c\/div\u003e\u003c\/div\u003e\r\n\u003cdiv class=\"detailmodule_image\"\u003e\n\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sca121206575b4fc4bc698eaa823ea5e6U.jpg\" class=\"detail-desc-decorate-image\"\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sb40593a8629d42adb82e45f8cdeb37de3.jpg\" class=\"detail-desc-decorate-image\"\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S6fed7ab530a44efd84efeb49ed4bf8c6k.jpg\" class=\"detail-desc-decorate-image\"\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S4b3761609efa4942a973dfd9e6f81b47P.jpg\" class=\"detail-desc-decorate-image\"\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S3f35703af2b345da98dc69468ae4bad7k.jpg\" class=\"detail-desc-decorate-image\"\u003e\n\u003c\/div\u003e\r\n","brand":"DOLLAR CHARM","offers":[{"title":"A5","offer_id":49347738632430,"sku":"14:200000060#A5","price":11.99,"currency_code":"USD","in_stock":true},{"title":"A4","offer_id":49347738665198,"sku":"14:100019335#A4","price":9.99,"currency_code":"USD","in_stock":true},{"title":"A3","offer_id":49347738697966,"sku":"14:201336238#A3","price":9.99,"currency_code":"USD","in_stock":true},{"title":"A2","offer_id":49347738730734,"sku":"14:175#A2","price":13.99,"currency_code":"USD","in_stock":true},{"title":"A1","offer_id":49347738763502,"sku":"14:100017028#A1","price":9.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/7065\/9566\/files\/S6d12964e233647ce89a9d5055b0d3e11D.webp?v=1785605290","url":"https:\/\/dollarcharm.com\/products\/for-1-4s-lithium-battery-accurate-percentage-display-low-power-consumptionmini-battery-level-indicator-module-with-smart-button","provider":"DOLLAR CHARM","version":"1.0","type":"link"}
