I bought this cheap 9watt led with buildin 2 18650 lithium. Perhaps i change these batteries with better ones. Including is also a lithium charger Ac to dc. I can charge ofcourse with a solar panel and stepdown module or lithium charger module. As you can see there are no electronics inside not even a diode.
my question is what happend if i turn the led lamp on while charging???
