They were only about 3\u00b0C apart for any temperature reading so I averaged the two readings.<\/p>\n<p>Ambient temperature = 27\u00b0C<\/p>\n<p>Temperatures at 1A:<br \/>\nTop external = 71\u00b0C<br \/>\nBottom external = 87\u00b0C<br \/>\nInternal = 108\u00b0C<br \/>\nBatteries = 53\u00b0C<\/p>\n<p>Those charger and battery temperatures are too high!<\/p>\n<p>The bottom was hot enough to be painful to touch and the internal temperature exceeded the 105\u00b0C rated max of the capacitors inside (see the photos). Those capacitors are quite temperature sensitive and shouldn&#8217;t be run at anywhere near their max rating to ensure a long life. That high of a temperature is also bad for every other component in the charger.<\/p>\n<p>In addition, the batteries were being heated up above the 45\u00b0C (approximately) point where aging of the batteries starts accelerating. The measured temperature of 53\u00b0C is what I would call &#8220;very warm&#8221;.<\/p>\n<p>In my opinion, this charger runs too hot at the 1A setting and could fail prematurely because of that. It will also heat your batteries up enough to possibly shorten their overall life some. I advise running the Efest SODA charger only at its 0.5A setting.<\/p>\n<p>Charger temperatures at 0.5A:<br \/>\nTop external = 49\u00b0C<br \/>\nBottom external = 55\u00b0C<br \/>\nInternal = 71\u00b0C<br \/>\nBatteries = 38\u00b0C<\/p>\n<p>Running it at the 0.5A setting does not guarantee that nothing can go wrong!<\/p>\n<p>I still recommend always charging on a non-flammable surface and staying nearby until charging is done. Then remove the batteries from the charger and store them in a non-conductive case or sleeve. Do not store your batteries in the charger!<\/p>\n<p>Never put any charger in a LiPo battery charging bag!<br \/>\nThose bags are made to only hold the battery pack. Putting the charger and batteries in the bag traps all the heat from the charger inside and the temperatures can rise high enough to cause failure of the charger.<\/p>\n<p>Images: <a href=\"https:\/\/imgur.com\/a\/DG90C\">https:\/\/imgur.com\/a\/DG90C<\/a><\/p>\n<p><a href=\"http:\/\/www.tasteyourjuice.com\/wordpress\/wp-content\/uploads\/2017\/06\/IMG_5611-e1497327542684.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-15689\" src=\"http:\/\/www.tasteyourjuice.com\/wordpress\/wp-content\/uploads\/2017\/06\/IMG_5611-e1497327542684.jpg\" alt=\"\" width=\"300\" height=\"589\" \/><\/a><\/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%20Avoid%20using%20the%20Efest%20SODA%20charger%20at%20its%201A%20setting\";<\/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>I have seen a couple of mentions of overheating and failure with Efest SODA chargers so I decided to check into it.
