After charging this electric bike battery for 10 hours by better solar power, full charged, we rode the bike, but hub motor wheel only run about 8km. <\/p>\n<p>We use a ampere meter in series to electric bike kit system, powered on and rode it. We got the current is about 5A. The speed is 257RPM.We use 26\u201d hub motor wheel.<\/p>\n<p>We calculate the speed is about 32Km\/per hour.<br \/>\nSee below formula:<br \/>\n\uff083.14\u00d726\u201d\u00d70.0254\uff09\u00d7 257RPM \u00d7 60 minutes \u00f7 1000 (m-Km)=32km<\/p>\n<p>If this is 10Ah battery, per hour lost 8ah.We can use 1.25 hours.<br \/>\nSee below formula:<br \/>\n10Ah \u00f7 8ah\/per hour= 1.25hours<\/p>\n<p>We think full charge this electric bike battery per time, the hub motor wheel can run about max 40 km. 32km\/per hour \u00d7 1.25 hours = 40 km<\/p>\n<p>There is definitely a problem with this electric bike battery, I\u2019m not sure whether electric bike kit is because of the solar charging or our testing, or if it has a fault. But I need a replacement electric bike battery asap, because we don\u2019t have any more 36v electric bike battery, and we sold 1 set of electric bike kit with lithium battery last week. I think BMS inside this electric bike battery no problem. The problem comes from the li battery cells. Maybe this electric bike battery had stayed in warehouse for a long time and haven\u2019t charged it. It will make the electric bike battery cut down the achieve distances and use life.<\/p>\n<p>So if solve this problem and let my hub motor to work asap, only replace all cells or replace new electric bike battery.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>We purchased an electric bike kit including motor controller, hub motor wheel, throttle, brake lever and with 36V 10AH bottle style Lithium Ion electric bike battery that used for testing 36V solar charger from one supplier, not from leaf motor. &hellip;<\/p>\n<p class=\"read-more\"><a href=\"https:\/\/www.leafmotor.com\/blog\/issue-about-electric-bike-kit-battery\/\">Read more &raquo;<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[10,13,74],"tags":[50,45,56],"class_list":["post-599","post","type-post","status-publish","format-standard","hentry","category-bike-conversion-kit","category-hub-motor","category-lithium-battery","tag-electric-bike-battery","tag-electric-bike-kit","tag-hub-motor"],"_links":{"self":[{"href":"https:\/\/www.leafmotor.com\/blog\/wp-json\/wp\/v2\/posts\/599","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.leafmotor.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.leafmotor.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.leafmotor.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.leafmotor.com\/blog\/wp-json\/wp\/v2\/comments?post=599"}],"version-history":[{"count":4,"href":"https:\/\/www.leafmotor.com\/blog\/wp-json\/wp\/v2\/posts\/599\/revisions"}],"predecessor-version":[{"id":1773,"href":"https:\/\/www.leafmotor.com\/blog\/wp-json\/wp\/v2\/posts\/599\/revisions\/1773"}],"wp:attachment":[{"href":"https:\/\/www.leafmotor.com\/blog\/wp-json\/wp\/v2\/media?parent=599"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.leafmotor.com\/blog\/wp-json\/wp\/v2\/categories?post=599"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.leafmotor.com\/blog\/wp-json\/wp\/v2\/tags?post=599"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
