A 20C discharge rate means that battery claims it can supply 100A @ 7.4V (740W) and be discharged in 3 minutes of operation. I don't have experience with RC bat

A 20C discharge rate means that battery claims it can supply 100A @ 7.4V (740W) and be discharged in 3 minutes of operation. I don't have experience with RC batteries, but I'm a little skeptical. That's an awfully fast discharge rate, and a lot of power from a 282g battery.
- baddox 9y agoIn the RC hobbyist community it's fairly widely recognized that manufacturers inflate their C ratings. That said, these things can definitely put out a scary amount of power, and discharging batteries in 3-4 minutes of flight isn't unusual for some high performance RC aircraft.
- snovv_crash 9y agoThat is absolutely normal in the high performance RC world. You even get 40C and higher rates cells. No point carrying around a heavier battery than necessary for the power required.
- pixelbreaker 9y agoI have a bunch of 4s Quadcopter batteries that are rated to 95c. If I fly hard I can run it flat (to 3.6v per cell) in 3 minutes
- Zak 9y agoI'd bet on that 95C being fraudulent (at least for more than a couple seconds at a time), but discharge in 3 minutes is 20C, and that's a lot.

- stpe 9y agoThis is from a respected manufacturer and they've got 2-cell 7.4V LiPo batteries with a 120C discharge rate. There must surely be a way to verify this claim? https://teamorion.com/en/news-and-racing/team-orion-ultimate-graphene-lipo-and-ultimate-graphene-lipo-hv-battery-lines-efra-legal-en/ https://teamorion.com/en/news-and-racing/team-orion-ultimate...
