Please note: The used li-ion battery must be able to be charged at least 1A and discharged by at least 3A. Do not use small li-ion batteries that can not handle this! In addition, this product is not equipped with temperature protection for the battery. So make sure that the battery can be charged in a safe environment to avoid possible fire hazard.
