I have driven the bike for a while without an issue. However, after 2~3 charges, the battery does not get charged anymore. When I plug the charger to the battery, I noticed that the charger LED still remains green. When it charged, it turned to red before. Would you please guide me how to resolve this issue?<\/p>\n<p><strong>A:<\/strong>The LED on your charger turn green quickly or can&#8217;t change color,it just means your electric bike battery doesn&#8217;t need to be charged.<br \/>\nCould you use a volt-meter to measure the voltage of your battery?How is the voltage?<br \/>\n<strong>Q:<\/strong>I measured electric bike battery:DC Voltage 30V.<br \/>\nThis is what happened:<br \/>\nI fully charged the electric bike battery over night and went to work on bike next day.<br \/>\nOn my return to home, when pushing down thumb throttle all the way down,hub motor was running for one second and down for two seconds and repeat. So I thought the electric bike battery was low.<br \/>\n<strong>A:<\/strong>If the voltage of your <a title=\"electric bike battery\" href=\"https:\/\/www.leafbike.com\" target=\"_blank\" rel=\"noopener noreferrer\">electric bike battery<\/a> is 30V that means your BMS inside your battery have been protected.<br \/>\nYou should take off all load,for example:headlights,led throttle,horn etc.Then the battery will return normal.<br \/>\nCould you disconnect all wires from your battery,then measure the voltage of battery again?<br \/>\n<strong>Q:<\/strong>Actually I measured 30V directly from the electric bike battery outlet. So there was no load when I measured it.<br \/>\nIs there anything I should check?I checked the output of the charger and confirmed that electric bike battery has output of 40V.<br \/>\nSo upon plug it into battery, if I still have green LED, then there is a open circuit in the battery?<br \/>\nIs there anyway I can check this electric bike battery at the charging inlet or power outlet without opening the battery package?<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Q:I bought DIY electric bike kit unit and a lithium electric bike battery and installed on my bike a couple of weeks ago since I had gotten one of the a couple of days ago and I wanted to use &hellip;<\/p>\n<p class=\"read-more\"><a href=\"https:\/\/www.leafmotor.com\/blog\/diy-kit-with-electric-bike-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":[74],"tags":[50],"class_list":["post-508","post","type-post","status-publish","format-standard","hentry","category-lithium-battery","tag-electric-bike-battery"],"_links":{"self":[{"href":"https:\/\/www.leafmotor.com\/blog\/wp-json\/wp\/v2\/posts\/508","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=508"}],"version-history":[{"count":7,"href":"https:\/\/www.leafmotor.com\/blog\/wp-json\/wp\/v2\/posts\/508\/revisions"}],"predecessor-version":[{"id":1739,"href":"https:\/\/www.leafmotor.com\/blog\/wp-json\/wp\/v2\/posts\/508\/revisions\/1739"}],"wp:attachment":[{"href":"https:\/\/www.leafmotor.com\/blog\/wp-json\/wp\/v2\/media?parent=508"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.leafmotor.com\/blog\/wp-json\/wp\/v2\/categories?post=508"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.leafmotor.com\/blog\/wp-json\/wp\/v2\/tags?post=508"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
