Hello, I plan on building an 8 inch long range copter and I am wondering how much efficiency I would gain for going for 8s batterys instead of 6s batterys. I would build my own batterys anyways so that isn't an issue.

I also would like to know if 1155kv motors are less efficienct then 925 kv motors (both are thobby velox 2812). If I just fly lower throttle on the 1155kv's is there any big difference.

Hello, I plan on building batterys for my 8 inch fpv drone. I would use an 8s2p configuration (built as 2 4s2p batterys for simpler charging) and reliance rs50 cells, my choice for spotwelder is the sequre sq-sw3 and I would weld a copper nickel sandwich (both 0.15mm thick). How wide should my copper strips be and are 0.15mm enough for a drone pack? Are there any other problems i should watch out for whulst building?
