Battery for Bravo Pump

I purchased the Bravo BTP Two Stage Electric Turbo Pump. They make a battery for this pump that cost over $100 with shipping. Has anyone figured out a cheaper way to hook up a rechargeable battery to these?

Below is a link to the battery.

Thank you,


you’re going to be near your vehicle and the pump runs on 12v, what about coming off your vehicle’s accessory plug and forget the battery?

How about a more expensive option

But, more advantages?

Try looking at a 7Ah smart battery. Much lighter, better at maintaining voltage under load and pretty much idiot proof.
A lead acid battery can be "cycled" about 1000 times, the Lithium Ion Smart Battery - up to 5000 times.

Not cheap, but better value.

I use the 7Ah and a 12Ah for bilge pumps (when in the kayaks) and for charging / providing power on camping trips.

Edit: that pump draws 20 Amps, you will need a bigger battery, the one they quote looks like its good for about 15 minutes.

Bravo BTP Two Stage Electric Turbo Pump’+4+GAUGE+PRIMARY+WIRE

buy 2 Curt 50’s wire in series….

Get a hand pump from NRS.

NRS hand pumps are waterproof.


The complete rig….including the Curts/Pelican box(s) n bilge pump…hydrophone plus the van computer/night fan aux electricity system for research ( we’re here looking for sociopaths) costs $$$ but not as much as kitchen cabinets.

plain jane 12 volt
Its just a 12 volt 6 amp battery. There are dozens of batteries you could buy. Say a motorcycle battery. Or like other poster said use you car battery. Do you want to take the battery and pump along with you? if so then you want a light weight battery. Nothing is lighter than a LIPO battery. Use them on my electric bilge pumps. Or you could get a lithium ion battery not quite as light as a LIPO. Amazon sells lithium Ion batteries.

Lipo and li-ion

Also note that a Lipo battery can deal with much higher current demands than a similar li-ion unit.

I guess the question is, do you really need the portability?

"costs $$$ but not as much as kitchen cabinets"
That is FUNNY!
