discharge is no problem AT ALL. sanyo L ncR 20700b 6612 Li-ion cells have a 15c discharge, & parallell 4x, you get 60c. this practice is not uncommon in Lipo batteries either. and NO- the problem is not size vs. watt hours. the power density of a 20700 is almost double that of the most powerful Lipo, including the case. the only comparison that matters is power to weight density. and for 20700's this is 106wh per Lb. if you want to see how that stacks up against Lipo, look online at the ...

The actual voltage of the single-chip lithium cell is 2.75~ 4.2v, and the capacitance of the upper mark of the lithium battery is the electric quantity obtained by discharging from 4.2v to 2.75v. The RC airplane lithium battery must be kept within the voltage range of 2.75~ 4.2v. If the voltage of the RC airplane lithium battery is lower than 2 ...

Getting Started with E-Power. Today, our hobby is enjoying a literal “Golden Age” of RC electric flight. The amount of quality motors, batteries, controllers and connectors is just about limitless as are the types and sizes of airplanes you can fly with E-power. Even though there are plenty of plug n play packages out there where you get ...

the reason why people don't use 18650 as power source for drone is the C rate problem or discharging current. for most 18650 battery packs, a 5C rate is sometimes hard to reach for most of the small manufacturers in china not to say 10C or 20C(technology is a problem, pricing is another problem, if more chinese companies can make batteries that ...

Electric RC aircraft are not known for long flight times, with multirotors usually doing 20-45 minutes, while most fixed wings will struggle to get past two hours. [Matthew Heiskell] blew these num…

As with any gas rc plane conversion to electric (or any electric radio controlled airplane for that matter), you will have to consider an ESC (electronic speed control). This hooks up to the motor, battery, and receiver. You will need to pick one that can handle the required number of battery packs, servos and have programmable features.

To allow for variations within a given size, manufacturers use partial cell lengths, such as half and three-quarters, and nickel cadmium offers the widest variety of cell options. Some spilled into the nickel-metal hydride but no lithium ions. There are other cylindrical lithium-ion battery specifications, sizes 20700, 21700 and 22700.

Does not make A123 bad, just not the best battery like people say here. I might still use them in certain cases in large models but even then I'd consider LION first and Relion to be precise. Besides why are we talking about A123 in a thread about LIPO vs LION, because some one always has to bring up their beloved and favourite battery.

To sum up: As lipo’s age and if they are misused, gases start to form in the battery and cause it to swell. Once you have a puffy lipo, the safe thing to do is to discharge it completely and then recycle it. If you want to learn more about lipo’s, check out my in-depth lipo battery guide. There I go into a lot of detail about all aspects of ...

With NASA’s help, Electric Power Systems (EP Systems) created this battery pack to power the Space Agency’s all-electric X-57 Maxwell airplane. The package houses thousands of off-the-shelf lithium-ion batteries and ensures that if one of them overheats, the problem won’t spread. As NASA develops its X-57 Maxwell aircraft, the Agency is ...
