just wondering if you guys have any sugestions on what battery i should get.i want everything to be powered with one power source. for probably 2 hours or more if possable. here is a list of hardware.
1) ez-b
2) one 2 amp h bridge powering one 12v motor
3) 4 high torque micro servos
4) 1 ultrasonic sensor
5) 1 8v camera hard wired to ez-b
i currently have it connected to the stock battery pack "fully charged it outputs 8.6v. but its not enough for everything. after about 5 minutes i start having hardware issues, ie...motors wont go forward, and camera starts blacking out because the battery starts draining,or its pulling to many amps... *confused*
thanks in advance, derrick
You may need to provide an external 6V supply to the high torque servos though, I had issues with 2 high torque servos taking too much power and browning out the LCD.
If it's just the 2A hbridge running at full power you will use 2A per hour, so a 5000mAh battery will run that for 2.5 hours.
Read up on LiPos though, undervoltage is an issue, as is incorrect use and charge. Don't worry about the paranoid scaremongers, batteries used correctly never explode...
I keep my cells above 3.3v when possible, I think 3V is the absolute minimum so it gives a little time for the robot to find the charging station and charge himself up (that part hasn't been done yet).
my ultimate goal is my vacuum robot. i'm just working out the hardware side of things now "testing & mounting everything"
this would be a good addition.
