{"product_id":"1s-3-7v-3a-li-ion-bms-protection-board","title":"1S 3.7V 3A Li-ion BMS Protection Board","description":"\u003cp\u003eUse this to protect a single lithium cell from over-charge, over-discharge and short circuit — the board sits between the cell and your circuit and disconnects it before damage. Commonly used on 18650-powered sensor nodes, wearable projects and DIY power banks where a bare cell would otherwise have no protection at all. Not suitable for loads above 3A continuous, and not suitable for LiFePO4 cells — the cut-off voltages are wrong for that chemistry and will either cut early or not at all. Key specs: 1 cell, 3.7V nominal \/ 4.2V full, 3A continuous, over-charge, over-discharge and short-circuit protection. Alternative: step up to the 2S board if your pack is two cells in series — a 1S board cannot balance or protect a series pack.\u003c\/p\u003e","brand":"Compoden","offers":[{"title":"Default Title","offer_id":53793458979181,"sku":"CDN-3095","price":49.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0999\/3997\/5533\/files\/1s-37v-3a-li-ion-bms-protection-board-8970504.png?v=1791035000","url":"https:\/\/compoden.com\/products\/1s-3-7v-3a-li-ion-bms-protection-board","provider":"Compoden","version":"1.0","type":"link"}
