About battery package for 9xr pro

[Tuz]

Hi all,

I want to use 18650 Li-ION battery with two cells package for 9xr pro , but I don't how to connect to radio. Can I just connect to radio with the left and
right two wires?

Yes, but watch the polarity. I don't have mine here right now. I also use 2 of those cells. Check the polarity with a 3s LiPo to see where the + and - wires go.

Hi jhsa,

Thanks, I got it, I will try it late.

Don't forget to also set the correct low battery alarm. For two cells I set mine to around 7.1 or even 7.2 volts. You could set it a bit lower but I guess there is no need for it as they don't take long to recharge. And you know you have enough charge to land if the low batt alarm sounds.
