So I have a dji wkm flight control with 4014 motors, and running 2 8000mah Batterys, I'm trying to setup the first and second level of protection for a heavy lift x8. Thanks for any info
What's your question? Are you looking for voltage levels? On my 6S NAZA copter (quad, but it makes no difference) I have first level set to 22.0V (warning) and second level set to 20.5 (land). Obviously you should do your best to not hit that second level when over water, or anything else that doesn't work as a landing zone. Knowing your copter and the batteries' discharge profile is very helpful. With my quad, I pretty much know exactly how much flying I have from 22.0V->21.0V, and I've never gone below 21.
Jason I always manual calibrate the voltage reading in the WKM setup software first than set the cutoff levels at 3.8V per cell for the first level than 3.5V for the 2nd. I do generally have to adjust from there after flying it and checking batteries to acheive the best flight time to battery safety ratio.
