So today, after a pretty long ride where the indicator started to dip into the red, I took off the covers and checked the voltage.</p> <p>The batteries were labelled:</p> <pre><code>Electier Danwant Silicone Power Battery 6-DW-38Ah (12V38Ah)</code></pre> <p>Before charging, the voltage on all 5 batteries was between 12.58V and 12.61V. During charging, it was from 14.5V to 14.9V. Then about 30 minutes after charging was done, they were between 13.52 and 13.54V. This is very close and within specs, so it looks like the batteries are doing fine and don&#8217;t need a <span class="caps">BMS</span>, at least for now.</p> Tue, 11 Mar 2008 16:18:00 -0800 urn:uuid:38d25539-b7fc-49e0-8de2-5a7dca85e5c7 Max Dunn http://blog.maxdunn.com/articles/2008/03/11/zapino-battery-report-1000-miles Electric Vehicles <p>That is quite good statistics. I hope all works well in the battery area because that is quite crucial in the longevity of any machine&#8217;s system.</p> Wed, 12 Mar 2008 01:28:28 -0800 urn:uuid:40c30dc7-5af3-43c1-931d-b25611af5699 http://blog.maxdunn.com/articles/2008/03/11/zapino-battery-report-1000-miles#comment-543
