The battery needs to be equipped with a protection board. The default is 2 strings. When changing to 3 strings, short circuit the contact, and then remove the side resistance. The equalization function can be used when two strings of batteries are connected. The BM pin is connected between the strings of batteries (the equalization speed is limited, and the parameters of the strings of batteries should be as consistent as possible when using).\u003c\/p\u003e\n\u003cp align=\"start\"\u003e◆ Current setting: The green arrow in the figure above indicates that the default current setting of two parallel current is 100K (0.9A) and 180K (0.5A). The resistor can be removed or replaced as required. Current calculation formula = 90000\/resistance value.\u003c\/p\u003e\n\u003cp align=\"start\"\u003e◆ Set battery charging cut-off voltage. The default voltage of a single string is 4.2V, which is the same value as ordinary batteries, and it does not need to be changed. To change, set the board’s VSET resistance according to the RVSET setting table.\u003c\/p\u003e\n\u003cp align=\"start\"\u003e◆ Set shipping timeout. By default, there is no timeout. Set the mold resistance value. 68K-4 hours, 120K-12 hours, no paste-24 hours.\u003c\/p\u003e\n\u003cp align=\"start\"\u003e◆ NTC access: Usually not used. If necessary, change the NTC resistance value to 82K, and connect the adjacent NTC and GND solder point to 100K thermistor (B=4100).\u003c\/p\u003e\n\u003cp align=\"start\"\u003e\u003cspan\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp align=\"start\"\u003eNormal use does not require a lot of units to be set, just select 2  strings to charge as required, unless you are special and familiar with the application.\u003c\/p\u003e\n\u003cp align=\"start\" data-spm-anchor-id=\"a2g0o.detail.1000023.i1.459fhbxdhbxdDV\"\u003e\u003cstrong\u003eLED indicator:\u003c\/strong\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eThe red light is normally on.\u003c\/li\u003e\n\u003cli\u003eThe blue light is on while charging.\u003c\/li\u003e\n\u003cli\u003eThe blue light is off after full charging.\u003c\/li\u003e\n\u003cli\u003eThe blue light flashes when an abnormality is detected\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Indian Hobby Center","offers":[{"title":"Default Title","offer_id":41939419922475,"sku":"5323","price":125.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/6796\/1387\/files\/61tCLul2fUL._SL1200.jpg?v=1753780001","url":"https:\/\/www.indianhobbycenter.com\/products\/type-c-usb-2s-bms-15w-8-4v-12-6v-1-5a-lithium-battery-charging-boost-module-with-balanced-support-fast-charge-with-indicator","provider":"Indian Hobby Center","version":"1.0","type":"link"}
