Friends
have you any information for the lithium ion 18650 battery and it's prescription. many people are talking and making diy battery pack for rc-flaying purpose in place of lipo!!!
Yes , a fellow modeler from our group ordered from aliexpress and made a 4S pack 3000mah and is now enjoying flights.
He has tested the pack on his flying wing and is getting more than 45mins of flying time on a single charge.
Good for applications using 30A esc only.

Yes they are much more effective than lipo as of light weight. But not use full that much in high current draw application.
