Why Run Lower C Lipo in Airsoft Gun

The complication is that with the lower C the voltage will drop and so the motor will not get the full 11.1v

It will turn fast because the battery will try to keep upward the wattage just it will damage the battery long term.

Essentially the C rating is the safety maximum constant power output for the battery before damage will occur.

Some batteries have a 2nd higher C number which is the Flare-up rating. This this is the highest momentary power rating.

I'm not sure the annotate virtually the driblet in voltage due to the lower C is entirely correct. The voltage should remain effectually 11.1v unless the current depict from the motor exceeds the adequacy of the battery, at that signal I would wait to see some sag in the voltage and RPM until the trigger is released.

The missing part of the jigsaw now seems to be the specfications of the motors. What input practise they require to achive a given RPM? There seems to be a lack of actual specifications on whatsoever of the websites I've been able to discover. If you were ownership a motor for a drone, expect at the specifications you lot tin find:

I'chiliad probably overthinking all this simply it's just a very bones electrical circuit and therefore, if you have all the specs, information technology should exist piece of cake plenty to compare apples with apples. At present I get that once you lot motion from the theoretical to the real world, there are a agglomeration of variables that y'all can't calculate for but an understanding of the theory is what I'm struggling with lol I should probably but shut up lmao

equally above, c rating ten capacity gives the rated electric current.

for example the to a higher place batteries in arwen'southward pic the nuprol has it calculated for the states, only the turnigy is rated at 1.5x35=52.5A continuous draw 105A burst describe.

the motor will try to draw what it wants based on the voltage regardless of what the battery wants to exercise, and a motor that tries to over-describe is equivalent to mildly shorting the battery. as EDcase says an over-fatigued bombardment will drop voltage but that's non a situation you desire to be relying on.

in mild cases this will reduce battery life, but in farthermost cases tin can crusade the battery to fire.

equally a general dominion if the battery physically fits in the gun there is zilch downside to over-rating the battery in terms of chapters (more than mah more often than not = bigger battery) or C-rating (which generally ways more than expensive battery). if the gun is too fast then you can either reduce the voltage, or change the motor/gears but you do not desire to reduce the current capacity every bit a means of dropping rof .

Yeah, you make some adept points there. Mainly that if we knew what the motor required, we could better match a battery to a motor with less of 'finger in the air' that seem to have to do. I guess the easiest thing to practice information technology just get a load of batteries and try them only "in that location should be a better way!"LOL

Thanks for your input anybody.
