Where can I get a battery

Albert Einstein -

Any 3.7v Lithium Ion cell will work, truth be told, but if you google the writing you find on the factory battery once you open it, you will likely find dozens of vendors on ebay, amazon, alibaba, wish, etc. personally, i removed the battery and ran leads from the factory battery wires to an external battery pack that holds an 18650 cell which significantly increased available maH
