Crazyflie2 charge current

Post by droneguy » Wed Sep 19, 2018 3:00 pm

Hello all,
Is it possible to increase the charge current of the CF2 from 400mA?
The BQ24075 seems to support up to 1.5A, and new batteries can be charged at 2C, is there a way to bump it to ~800mA?

Seems like enabling this should work - correct?

Is this advisable?

Yes, un-commenting the line you linked will increase the charge current. There will be no problem on the Crazyflie side but your battery has to handle it otherwise it will loose capacity faster than with 400mA charge.
