Before using the balancing function, users need to set the basic parameters of the battery and download the extreme space BMS-APP. After downloading, set the battery type on the parameter setting page of the extreme space APP. For default parameters, see Chapter 4.\u003cbr\u003eUsers can set the balance trigger pressure difference (mV) in the parameter setting of the APP. When the balance is turned on, the balance will be turned on automatically when the pressure difference of any two strings of batteries in the battery pack is greater than the set value, and the balance will be turned off when the pressure difference is less than the set value. The default balance current is 2 A. Users can adjust the balance current according to their own battery capacity. It is recommended that the balance current not exceed 0.2C of the battery capacity (C). If you do not need the balancing function, you can set the balancing switch to off in the BMS control page of the APP.\u003cbr\u003e\u003cbr\u003eSparameter\u003cbr\u003eModel:JK-QB2A8S20P ( Bluetooth heat display funcstions)\u003cbr\u003eSupply voltage: 12-40V\u003cbr\u003eMaximum balancing current: 2A\u003cbr\u003eMaximum charging current: 200 A\u003cbr\u003eMaximum discharge current: 200 A\u003cbr\u003eMaximum instantaneous current: 400 A\u003cbr\u003eMaximum starting current: 3000 A\u003cbr\u003e\u003cbr\u003eBattery type: Ternary lithium battery =3s-8s\u003cbr\u003eLithium iron battery= 4s-8s\u003cbr\u003eLithium titanate battery=7s=8s\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Se3f913d71c0b4ff3bc76396ebf0ca7231.jpg?width=1200\u0026amp;height=2198\u0026amp;hash=3398\"\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S7635a19f35e94472babd08010bbf6bdcS.jpg?width=1200\u0026amp;height=2173\u0026amp;hash=3373\"\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sfdb34b7c8b7f4672ae2381c8597a8eebg.jpg?width=1200\u0026amp;height=1604\u0026amp;hash=2804\"\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S408aea1f351d4e58a919cd1ab86ce312S.jpg?width=1200\u0026amp;height=1550\u0026amp;hash=2750\"\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sef0e114a906543f4b4f381c25239113f0.jpg?width=1200\u0026amp;height=2256\u0026amp;hash=3456\"\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sc64b647634c14f8f885d8ebb4ff95ad3A.jpg?width=1200\u0026amp;height=1734\u0026amp;hash=2934\"\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S576b825469514cfbbbeee5cf78e3c2f6i.jpg?width=1200\u0026amp;height=2266\u0026amp;hash=3466\"\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S0dc582227886417fb558044a21484898i.jpg?width=1200\u0026amp;height=1848\u0026amp;hash=3048\"\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S9f350f31be8d4a3e8b4b0542c0531361n.jpg?width=1200\u0026amp;height=1433\u0026amp;hash=2633\"\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S43f951a1c1724c88ab285cea92effe41f.jpg?width=1200\u0026amp;height=1952\u0026amp;hash=3152\"\u003e\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"JKVOLT","offers":[{"title":"JK-QB2A8S20P","offer_id":48354642657469,"sku":"JK-QB2A8S20P","price":64.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/3338\/1309\/files\/JK-QB2A8S20P.png?v=1788251411","url":"https:\/\/jkvolt.com\/de\/products\/jk-qb2a8s20p-truck-bms","provider":"JKVOLT","version":"1.0","type":"link"}
