My goal is to achieve long flight times for cinematic flying only—I don’t do freestyle or acrobatics.
I’m using Molicel INR21700 P42A Li-ion cells and would like advice on which battery configuration to build.
Im using 4S2P setup on 560mm quad carring gimbal with 13 inch props and i can say i like it, i get over 30 mins of flight time on it. Not sure about your motors how they are efficent on 4s vs 6s. But for sure weight between 4s and 6s is big so for cine crusing i guess you will get better flight time with 4s.
Thank you all for your valuable time.
Upon further research, I found that my motors — Flywoo NIN V2 2806.5 1350KV — are most efficient when used with a 6S setup. Additionally, since lithium-ion cells perform better with lower current draw, using a higher voltage (6S) system helps reduce the current. Therefore, I should go with either a 6S1P or 6S2P configuration. However, since the 2P setup will be heavier, the 6S1P option seems more suitable.
I would go with the 6S1P setup. The 6S2P would give you more flight time - but probably only 35% more flight time for a 100% increase in battery capacity.
I use 6s2p for my 8" drone, but this is almost 2kg total mass. It can fly over 30 minutes, but I am considering switching to 1p - probably not much shorter flight time but much lighter and agile drone.
