I received quite a few messages from people wondering how I can say that because they get great performance from their LiPo&#8217;s. And they should! Not meeting the 100C, 70C, or even the 50C ratings these packs have doesn&#8217;t mean they are lousy performers. It just means they don&#8217;t perform anywhere near their ratings. They can still be better than the 18650&#8217;s we use.<\/p>\n<p>For example, see the graphs linked to below.<\/p>\n<p>I tested two 3S 1800mAh-1850mAh LiPo packs against a 3S setup of Sony VTC5A batteries in a good quality battery sled at 10A, 20A, and 30Ap. Their DC internal resistances are:<\/p>\n<p>Green LiPo = 0.028 ohms<br \/>\nRed LiPo = 0.044 ohms<br \/>\nVTC5A&#8217;s = 0.078 ohms<\/p>\n<p>You can clearly see the difference the different internal resistances make. The higher the internal resistance, the greater the voltage sag and the lower the battery voltage is.<\/p>\n<p>The Green LiPo is the clear winner here with the Red LiPo performing next best and the VTC5A&#8217;s performing the worst of the three. Interestingly, the Red LiPo is a very expensive pack from a very well respected manufacturer. The Green LiPo is slightly larger but is about half the cost and performs a lot better. I won&#8217;t be revealing the manufacturer&#8217;s name for either LiPo until I can test a second pack from each company to make sure my results are correct.<\/p>\n<p>Neither LiPo performs anywhere near its ratings but in spite of that they still outperform a pack using one of the best 18650&#8217;s available.<\/p>\n<p>There are safety issues when using LiPo&#8217;s though. I&#8217;ll be addressing these, and other considerations, when I have finished testing the rest of the 1800mAh-1850mAh LiPo packs. I hope to be able to do that within a couple of weeks.<\/p>\n<p>https:\/\/imgur.com\/a\/fch74<\/p>\n<div style=\"padding-bottom:20px; padding-top:10px;\" class=\"hupso-share-buttons\"><!-- Hupso Share Buttons - https:\/\/www.hupso.com\/share\/ --><a class=\"hupso_toolbar\" href=\"https:\/\/www.hupso.com\/share\/\"><img decoding=\"async\" src=\"https:\/\/static.hupso.com\/share\/buttons\/dot.png\" style=\"border:0px; padding-top: 5px; float:left;\" alt=\"Share Button\"\/><\/a><script type=\"text\/javascript\">var hupso_services_t=new Array(\"Twitter\",\"Facebook\",\"Google Plus\",\"Pinterest\",\"Reddit\");var hupso_background_t=\"#EAF4FF\";var hupso_border_t=\"#66CCFF\";var hupso_toolbar_size_t=\"medium\";var hupso_image_folder_url = \"\";var hupso_url_t=\"\";var hupso_title_t=\"A%20BATTERY%20MOOCH%20POST%3A%20LiPo%27s%20don%27t%20perform%20like%20crap\";<\/script><script type=\"text\/javascript\" src=\"https:\/\/static.hupso.com\/share\/js\/share_toolbar.js\"><\/script><!-- Hupso Share Buttons --><\/div>","protected":false},"excerpt":{"rendered":"<p>Just because LiPo&#8217;s might have preposterously exaggerated ratings doesn&#8217;t mean they don&#8217;t still perform well against 18650&#8217;s.
