Review on Biswaye Battery Adapter DCA1820 Convert by John Gray

This adapter is just what you need to keep your old 18 volt tools in working order when they are officially no longer in use. Bought after reading reviews that my FlexVolt batteries can also be used, the factory adapter is connected in such a way that it is not compatible with the FlexVolt system (at least according to the literature). FLASH. As tested, this adapter works with FlexVolt batteries. The 9Ah battery on some of my power-hungry tools is great. I am amazed at the number of reports that it will not "CHARGE" batteries when ALL descriptions and literature indicate that it is not designed to charge LiPo batteries. , just to attach them to tools for use. It never surprises me when people who haven't read the instructions have problems with things. A NOTICE. Do not leave your LiPo batteries in this or the DeWalt adapter. They work if you leave them connected. You can leave the adapter in the device and remove the battery only between uses.
