Ballast Pump Flow Comparison

I know this is a old post.
But what about the current limitation of the 2amp charger feeding pumps that require 11.5 amps(water puppy)?
The information is great though.

Im not sure I understand what you are asking, can you put it in some context? The RPM of a simple DC motor like a pump will be effected by voltage and available current. This would effect its output.

I think he means you need a bigger charger to act more like an alternator to keep up with the draw of the heavier output of the reversible pumps

...so he can run it without a battery? Or...?

Oops I missed a point.
I thought it was just the charger and not the battery and charger.
Now I feel pretty dumb.
Great write up though.
What pumps did you end up running?
