{"product_id":"4s-16-8v-40a-bms-with-balancing","title":"4S 16.8V 40A BMS with Balancing","description":"\u003cp\u003eUse this to protect and balance a four-cell lithium pack where the draw is high enough that a 20A board would be the weak link. Commonly used on 4S rover packs, high-current servo rigs and 14.8V assemblies. Not suitable above 40A continuous — and read the board's own body text, because boards printed 40A sometimes state a 20A working current in their own description. Key specs: 4 cells, 14.8V nominal \/ 16.8V full, 40A continuous, balanced. Alternative: the 3S 25A board if your pack is three cells — a 4S board will not protect a 3S pack correctly.\u003c\/p\u003e","brand":"Compoden","offers":[{"title":"Default Title","offer_id":53793459536237,"sku":"CDN-3098","price":159.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0999\/3997\/5533\/files\/4s-168v-40a-bms-with-balancing-1141187.png?v=1791034999","url":"https:\/\/compoden.com\/products\/4s-16-8v-40a-bms-with-balancing","provider":"Compoden","version":"1.0","type":"link"}
