is 12v motorcycle battery (maintenance free) is good for robot?.

oric_dan(333):
The Omnibots come with a little 6V wallwart to recharge the battery. SLA requires nothing
special, unlike Nicad, NiMH, and Lithium.

Larger Amp-Hr batteries won't harm your electronics, as the Arduinos only draw as much
current as they need. But powering an Arduino from 12V will often cause the tiny surface-
mount 5V regulator to overheat.

For robots larger than tiny, I favor using different sets of batteries for motors and
electronics, then the motor electrical noise doesn't get onto the processor board as easily.
I always use NiMH AA-cells for the electronics, no matter what I use for the motors.

o thank you very much for your reply.

do your 6v sla battery weight is less than the 12v battery of motorcycle?

how long do Omnibots run from full charge to empty? i mean how many hours.?
