Each cell comes in a new heat-shrink wrap with an insulating ring on the positive terminal and is ready for assembly. 100% of cells are tested and sorted: this group has a capacity of 4.4\u20134.6 Ah and an internal resistance of 13\u201314 mOm. Use cells from the same group in one pack so the cells work evenly and charge uniformly. The lower the internal resistance, the better the cell handles current and the less it heats up. For a pack built from identical cells, the difference between adjacent resistance groups is small. What matters is that all cells in the pack come from the same group. For convenience, we can laser-weld bimetallic aluminum\u2013nickel contact pads onto the cells. Such a pad makes it easy to solder a wire or spot-weld a nickel strip. The service costs UAH 20 per cell.<\/p>\n","protected":false},"excerpt":{"rendered":"<p class=\"mpb-crm-spec\"><strong>Origin:<\/strong> disassembled Tesla batteries<\/p>\n<p class=\"mpb-crm-spec\"><strong>Form factor:<\/strong> 21700<\/p>\n<p class=\"mpb-crm-spec\"><strong>Capacity:<\/strong> 4.4\u20134.6 Ah<\/p>\n<p class=\"mpb-crm-spec\"><strong>Internal resistance:<\/strong> 13\u201314 mOm<\/p>\n<p class=\"mpb-crm-spec\"><strong>Insulation:<\/strong> new heat-shrink wrap + insulating ring on the positive terminal<\/p>\n<p class=\"mpb-crm-spec\"><strong>Quality control:<\/strong> 100% of cells tested and sorted by capacity and internal resistance<\/p>\n<p class=\"mpb-crm-spec\"><strong>Service:<\/strong> laser welding of bimetallic aluminum\u2013nickel contact pads for soldering and spot welding \u2014 UAH 20 per cell<\/p>\n","protected":false},"featured_media":176330,"comment_status":"open","ping_status":"closed","template":"","meta":{"_monsterinsights_skip_tracking":false},"product_brand":[],"product_cat":[405],"class_list":["post-176287","product","type-product","status-publish","has-post-thumbnail","product_cat-battery-cells","first","instock","shipping-taxable","purchasable","product-type-simple"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.2 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>21700 Tesla Battery Cell (salvaged) 4.4\u20134.6 Ah \/ 13\u201314 mOm, in heat shrink with insulating ring - Power for the military and for home.
