OMG guys the Samsung are one of the hadest5 hitting best batteries out. They ae 20 amps only cuz samsung is really conservative on their numbers unlike efest. They outperform the sony vtc4 and 5, lg and all the efest 18650's. They have been tested fine at 30 amps cont, we have had this talk many times. Also these reg devices never pull that much especially the sig100. you aent pulling over 20 amps anyway...bottom line they ae one of the bes if not the best batts you could have gotten period.
