Amp Rating
Ok - I thought I understood electricity ratings (watts, volts, amps). I know volts and undestand watts is a measure of work - but amps are a capacity. So when a motor has a rating of 12volts and...

So - 12 Ah battery would suffice for this?
Acid batteries must maintain a certain voltage when doing the work, and, although theoretically a 12ah battery would work, you may find the voltage drop would be too great at a 12a draw. That 12ah rating may be at say, 1 amp draw, not 12. The greater the load (amp draw) the more capacity you need to maintain a working voltage.
Lithium batteries change all that, as they can maintain voltage no matter what the load. They are light weight, expensive, used in drones and yard equipment, and generally higher voltage.
