USB phone battery to Lowrance fish finder?

I have one of the small rechargeable phone batteries that you can connect to a cell phone to power it. It's a 3000maH one so it could power my little Lowrance fish finder for a while.

How easy is it to splice the USB wire into a regular battery harness to the fish finder? The battery uses a mini USB I think, so I hope to cut it and splice it to the finder.

I read where USB cables have 4 wires. Is that correct and which ones do I splice to? I'm pretty decent with electronics but have never cut one of these cables.

USB power is 5v. Cell phone batteries are typical 3.5v to 4v range. I believe you may have a problem with a single battery.
USB power wires are typically red and black.

I mention typical because China is in the mix.

It's a lot like this one: http://www.bestbuy.com/site/axxess-5...?skuId=4935917

The output is USB voltage (5v). Typically, you need 12v to power Lowrance units.

Okay. Thanks.

This would work. Your unit type will determine the active run time of the battery.

Yeah, I have one. I was just curious about whether the small rechargeable one would work because I have 2 of them sitting around.

ok. There are small lithium ion batteries on the market that pack a punch. I use all sorts of battery packs in my R/C stuff.

You can take the 5v battery and boost it to 12v with the right contraption.

This would let U use UR power packs. Need a std to micro connector adapter and connect output per polarity.

Dc to Dc boost converter is what this device be. Good for 2 amp out current. Your head unit prob @ about 1 amp continuous.
