Just finished the wiring for a saber build, and the blade won't turn off once its turned on without inserting the kill key to completely power off the saber. When I ignite the blade, it is also just white rather than whatever color I try to set it to, and it turns on all at once rather than sequentially (it's a neopixel blade). I'm using a normal 18650 battery, and I've read a few places that a 15A battery might be needed for neopixel sabers, is that what is causing my issues?
