3DSAVAGE

I just got a dynam devil 3d PnP and I needed some batteries for it. I ordered a couple 25c 2200mah 3 cell li pos, but the box says it needs a 4 cell. The 4 cell recommended has the same discharge rate as the 3 cells I ordered. Are these batteries going to be under too much load? Running the stock 650kv motor, 50 amp esc, and a 13x6 prop. I looked online for some discharge rate calculators, but they give me some strange and somewhat ridiculous numbers like I'm pulling 160W.

So will the 3 cells just puff up and blow on this setup? Or will it just be gutless in the air?

The number of cells multiplied by the individual cell Voltage = the total Volts (power).

The number of mAh = how long it will last. 2300 mAh will deliver 2300 mAmps for an hour - where 3000 mAh will deliver 3000 mAmps for an hour.

Gutless would be an understatement!
A 4S setup running on 3S will pull much less current from the battery and performance will suffer.
save the 3S batteries for another project and get some 4 cell batteries.

160 watts you sure? 50 amp with either 3 or 4 cells.battery C rating will also matter. you could run this bird on those batts.but flights will be shorter .watts Amps times Voltage+ p or watts..so 160 hmm..id say 12v X 50 amps nope its going to be like 60+ 700+ watts.not 160.. your still going to pull less when you throttle down say 400 my maths correct
