As I read through the forum I notice a few people having concerns about batteries, that said,
I have found a solution for powering all my bots including a 19 servo, wireless camera, fan cooled, MCU controlled servo board, wireless PS2 controlled , Xbee wireless serial ,six legged Hexapod....that's a mouthfull...
I use Lipoly batteries 7.4V to be exact and a Castle Creations BEC or 2
The Bec can be programmed to output anywhere from 4.8 volts to 9 volts and can have an input voltage of 5 volts to 25.2 volts
It can supply up to 10amp Peak and give a constant 7amp output!!!
Canadian price from my only hobbies shop in town is $39.00
The lipo battery I use is a 5000 Ma. at 7.4 volts
Just a thought for batteries.
