Is the min voltage under load for a lipo 3.5V or 3.3V not to damage them?
Also, I’m thinking about building my second brushless (hopefully much better than my first since now I know what not to do haha) and I have a couple battery questions.
In your experiences, for 3S/4S lipos, what’s the voltage drop vs mah and amp draw?
For example, my Emax 1106 4500KV with a 3045 prop and Tattu 3S 450mah 75C lipos drop to 3.5V/cell during punchouts. My OSD says that the four motors draw 40A during punchouts, so under a 3 Second 40A load my lipos drop to 3.5V.
Obviously increasing my batteries mah will decrease the voltage drop under load, but I wonder if anyone has any advice as to what’s a good combo? I’d be willing to get with 4 inch props if I can get the total weight less than 250g and the thrust to weight over 10.
Maybe those of us with current monitoring can post their total max amp draw during a 3 Second punchout and their cell voltage during punchout and we could make a table so we’d know what mah to pair with what amp draw?
