@@muffineateromnomnomnom i am glad you sent feedback. Yes i should be more clear on video. Basically want to know is it safe to charge old lithium with unkown data from other lands . Continious in extream conditions also sort a disclaimer as in my view this may not be safe. Ie i purchased a new model with a larger battery. That wont need charged like this. Also i use this same setup for my head led light so wanted to know what people think. Man i just prob need to make a better video LOL
