Build an autonomous Wall-E Robot

Step 11 Battery.. POWER!

Because my wall-e does have 6 servos and a microcontroller, his power consumption is high.

Due to size constraints, i was limited to a small battery.

My choise was a 2000mha LION 7.4v cell. LION batteries don't like to be drained, so be prepared for a low life expentency.

The 2000mhz battery gives my wall-e about 60 minutes of life between charges.

You can purcahse your battery at any Battery Depot or similar outlet.

With all the space available inside, why didnt you go for a bigger battery, or would this strain the drive train too much?

it's a 2400 mha 7.2v battery. runs for hours. it's lithium-ion.
there is absolutely zero space available. the tiny battery barely fits. there are multiple size toys, and the most common is the remote control wall-e (which this is not). check my youtube channel www.youtube.com/aliencurv for a video of my larger wall-e
