Higher Capacity batteries for DARwIn-OP from RoboSavvy

Hi all

All those who own a DARwIn have felt the low run times the standard DARwIn-OP battery provides.

The stock battery that comes with the robot is only 1 000mAh (the same as a Bioloid PREMIUM) but on DARwIn it's powering way more equipment: more servos, more hardware including a FitPC2i and camera) making it's run time about 10 minutes from our experiments.

The cavity for the battery has also got plenty of room to accommodate a much larger LiPo.

Therefore, we were able to source a higher capacity LiPo (1 550mAh) and the appropriate connectors.

1 550mAh is not yet the ideal for such a large robot but it's a good improvement over the standard battery (1.5x more power).

The other advantage is that this battery offers much higher discharge rates (20C which, on a 1 550mAH battery means 3.1Amps triple what the standard battery can offer)

The battery as well as the necessary adapter can be found bellow:

Adapter to XT 60 (the connector used by DARwIn):
