I have a 250w dc water pump
And I usually use it with solar directly to water my garden.
But there's no sun and I planted a few trees.
What can I use to power it?
I have a couple of 12v batteries but I'm afraid they would burn it if I just stuck them in series.
Any ideas?

Well for one, you could use a 250W AC to DC adapter. Also it might help to know what is the rated voltage of the pump before thinking about seriesing and paralleling.

You can possibly get them cheaper locally if you look for ultra-cheap poland import LED drivers with the 24V 15A spec, but it's probably not gonna be less than 15 euros + shipping.

Your battery idea would work, any 24v motor is going to be 30v-tolerant, but you still need some way to recharge the batteries, and some way to keep the pump from completely draining them, so it's not an especially good idea if you have AC nearby.
You could also very likely buy a cheapo AC pump for $20 or so and water your garden with that.

This is why you don't respond to tripfags.

I hope you removed that blue plastic over the inlet.

Shut the fuck up. I'm an engineer, I can fix this with the proper data dumb ass.

Ok, join two 12 volt batteries together in series to make 24 volts, then wire it up directly to the pump. As for a charge controller. search Amazon for MPPT. I just bought this one and it's working very well.

Two 12V batteries in series will run the pump.

just use any AC adapter for sockets that delivers enough W to power it
if you understand a parallel battery configuration you should be fine to figure it out ... its just + and - you have to attach

Won't they push too much amps?
