Am working on a new project by solar charging Li-ion cells by connecting 3x 18650 3000mah batteries which i have as spares which comes with built in overcharging and discharging pcb. Connnecting them in series to make 11.1v. 12.6v when fully charged and hopefully run 12v lights. While i was browsing i came across someone selling a special solar charge controller max 3amp for solar charging Li-ion cells.
According to the seller you can use normal solar panels as the the controller can take 15-25v. My question is that if its possible and if safe to do that if there is anything alse i need to know about? These are so light and have low discharge rate to an SLA. Here is the link to controller http://cgi.ebay.com/ws/eBayISAPI.dll...m=320544708532
