So I am working on a project with an Arduino and a PCA9685 by Adifruit and I need some help. So I am using the PCA 9685 to power 16 servos, so it's going to be supplying a good amount of power. Here's where the problem is going to come in; I need to be able to power this off the ground (I'm making something that is gonna fly) and I don't think that rechargeable AA's Adifruit mentioned are gonna cut it. The input port for power is just a + and - port that takes male jumper cables. Adifruit said it could take 4.8v or 6v rechargeable batteries sold by hobbyshops. I did some research and figured out that it's going to be quite difficult to recharge these batteries, forgetting the fact that it could be dangerous(I've had a NiMh cell blow up in my hand before; however, it was just one of the eight). I'm wondering if there is a way to attatch or plug in a port to the PCA9685 that would take power from a 3000+ mAh 4.8v-6v battery that contains standard connectors that would allow me to unplug the battery and plug right into a NiMh charger.
