[QUOTE="CWatters, post: 5696370, member: 423469"] There are modules like this that can be adjusted to convert 5V to the 13.8V approx needed to charge the battery. [URL]http://www.banggood.com/DC-DC-Adjustable-Step-Up-Power-Module-p-971005.html[/URL] If your panel is only 15w and you want to power 165w load then the charging time will be at least 165/15 times as long as the discharge time. Eg if you want to run the bulb for 10 mins you will have to charge the battery for at least 10*165/15 mins at the very least and probably 25% longer to allow for losses in the battery. [/QUOTE]
