If the battery cost less than the thing you're powering, then you should probably discard the battery. If you're stubborn (or very strapped for cash) and the battery didn't catch fire when the original damage happened, then it might perform okay, but I'd say there's a moderate chance of fire, especially at high currents. Check battery voltage with a ...

You're really asking two questions here: Will the motors and propellers be able to provide enough thrust to lift the weight of the quadcopter? There's no substitute for measurement here. Get one motor, one propeller, and measure it for yourself using a benchtop power supply. Then multiply that by 4 (scaling it by the ratios you posted, as appropriate) ...

Buy the imax b6. They're cheap to replace at $26, I would recommend buying the imax b6 with the built-in power supply as it saves you having to buy an extra 12v 5A psu. I own 4 imax b6's and they work wonders.

The short answer is "Yes", Rocket motors are less energy dense because they are built to expend that energy more quickly, while Lithium Ion Polymer batteries are designed to work longer. However saying that they are "100 times" cannot always be correct. The reasoning being that not all Lithium Ion Polymer batteries are made equal. You have different C ...

The Ah rating is a measure of charge - how many amps the battery can supply, for how long. In your case you need 5A for 1 hour, and that is simply 5 Ah. You multiply the current by the time required, to get the charge needed. Next, The voltage rating is basically how many cells are used to make up that battery. You can't control that - you just have to get ...

Have you tried to connect the PAD supplied with the HSB servo the fifth picture on this page? It is not necessary but in the case that your battery is fully loaded it an cause an overload if you don't have a BMS in your circuit. This depends on the battery you are using. Usually they are given with a value in mAh which correspond to the maximum amount of ...

You don't gave all information that are needed for such calculations. However, the technical details of the Thrusters give a peak consumption of 350 Watts each. So you have 6 of them, makes overall 2.1kW/h. Lets assume your Batteries have the following details: 6S 22.2V 3300mAh. Therefore the amount of energy the Batterie stores is: 22.2V*3.3Ah = 73.26W/h. ...

I'm 14, please pardon me for any rookie sentences... As far as my knowledge goes with Lithium Polymer batteries(not very far), they don't explode with a Hollywood style explosion, where flames go everywhere and everyone dies. Instead, LiPo's start to smoke and the plastic cover on the outside layer of the LiPo will start to expand, when it cracks it ...

Assessing damage from a picture isn't going to tell you anything concrete. If you're already considering discarding this battery, you might as well test its electrical properties (and physical properties) against an intact replacement. At a minimum, you should check whether the damaged battery has more internal resistance (i.e. can't supply as much ...

What exactly are you trying to do? You have an 11.1 volt, 5000mAh battery pack. That is, you have a (11.1*5)V-Ah battery pack, or a 55.5 Wh battery pack. A micro USB connector can safely pass 9W of power, meaning it would take (55.5Wh/9W) = 6h10m to charge, assuming you could perfectly utilize all of that power. You should consider instead either: Take ...

Proper Lithium Ion battery fuel gauging and management is not really used in the hobby world. System specific batteries (3DR Solo, DJI Phantom) exist but generic components for people building their systems from components do not. Probably not worth the cost for mini-quad racing type stuff. Possibly a business opportunity for prosumer systems.

I think the main difference is that the energy in the rocket engine is (probably, I'm not a rocket scientist) far less effectively used than the one of the LiPo. Also, the actual weight of the fuel in the rocket engines might be way lower than the weight of the engine (so your masses are not consistent, one is only the battery/"fuel", one includes the motor)....
