Can't really begin to guide you as your post lacks much relevant detail. Probably not many will be able to assist you for the same reasons. I do not know which batteries you are using (you state model numbers but not brand/versions). You mention the black 16340s and those are not IMR. 16340 is not a recommended battery. Kick instructions clearly state IMR ONLY. If using a single IMR 16340, those have only 550 amps and kick boosts which uses more amps so they certainly will drain faster on such a small battery. If you are stacking the batts, they are not supposed to be stacked. You are trying it in a device that is not a tested or verified device on the Evolv website kick page and that means you are using it out of spec. You are also jerry-rigging wires and that is also out of spec. So, from what little detail you do provide, you have voided your warranty by using the incorrect batteries, using it in non-tested/verified devices and jerry-rigging wires. I'd suggest you read the instructions page on the kick website here: The Kick – Instructions « Evolv Hope this is somehow helpful. FWIW - over in the GG subforum there is a big thread on various configurations people are using the kick in GGs. You might spend some time reading thru that thread to learn how to get the best results in your GG.
