Using a lipo to power 12v fuel pump?
I currently have a sullivan streamer that I have been loving thus far. My only complaint is the weight of the 12v battery I put in my field box, the weight of it really kicks in after a good walk to the field. So, I was thinking I could hook a 3S 2200 lipo to the streamer to power it. This type of lipo powers my starter, so it should work for the fuel pump, right? The only issue I see is maybe the wires from the streamer, too thin possibly?

I wouldn't want a battery that could self combust by a short or thermal runaway anywhere near my fuel. I would use A123 Batteries before I would use LiPo's. Much safer.

I use an old 3s 1500 LiPo to power my fuel pump that sits on top of the fuel bottle. No problems at all - but I do disconnect at the end of flying.Vibe 90, Vibe 50, Vigor CS x2,

I made a mount for my fuel pump attached to the sullivan cap with the lipo strapped to the side of the jug. It's a beautiful thing

I've used a "retired" 3s 2100 for years on my pump.
The only issue is if you let it get low enough that it doesn't pump, you'll ruin the pack.

That wouldn't matter. Just because you change the power source doesn't mean it is all of a sudden pulling 30 amps.

Same here!

Recycled 3s lipo running my Pump. Simple easy and a Velcro Strap is all you need.

Definatly use caution on battery selection, but Its not to often, that a Lipo "Burns Up" while in a model.

Now for that, I do of course remove the lipo while charging! And I use caution while transporting and storing the fuel.

Just my Opinion....

consider a 2s lipo or an old tx batt
i burnt 2 fuel pump motors using a 3s

i have used a 2s rx pack, they dont last very long and u have this worry about over discharging.

now, peace of mind, i use a spare nimh that came with my jr tx.. they seems to last for ages and i dont have to worry about over discharging.

I've been using the SlimLine SL-2000 on-bottle 12V fuel pump on an old 1500mah 3S lipo for 2 years with zero issues. I've taped the lipo directly to the pump so it's completely portable.

All the ones i have used started leaking but still pumped fine,they pump extremely fast on 12 volts.i have switched to a 2 cell lipo and it does pump a little slower but still plenty fast.i'm hoping they will last longer with the lower voltage.

Same as Anthony.L. Only issue is that because the LiPo lasts a few gallons, I have forgotten to charge it so makes sure you have a spare LiPo in your field box!Vibe 90, Vibe 50, Vigor CS x2,

I've Thought About It . . .
using a lipo to pump fuel into my heli. Although, I have been happy my setup thus far. No trouble with wires, no chance of overdischarging, no forgeting to recharge, no forgeting it at home . . . it's called a hand pump . Just kidding.
I do have three 3S lipos that have 1 cell in each pack either bad (won't hold a charge) or been damaged from a crash. When I get a chance I'll have to take out the bad cells to make 2S lipos and try those to pump fuel.
