flounder light batteries?

[pcbayou]

Any recommendations on a good 12-volt battery for our new flounder light, and a good place to get one, inexpensive? The light is hand-held, 23 watts, pulling 1.9 amps. We'll probably try the old float-it-on-a-tube trick for wading. But I'd like to have a compact battery (rather than the usual 12V car type). I've read and heard that you can even use smaller, lawnmower-size batteries in a backpack for wading.

Growing up we used a motorcycle battery... my mom made a carrying pouch that went over my shoulder.

Not sure how much our bulb pulled. It was an RV 50 watt 12 volt bulb.

Thanks -- that does sound do-able, and it would keep things simple.

Amps = Watts/Volts 50w/12v=4.16a

Dad gum motorcycle batteries cost almost as much as a full size. Academy has its marine on sale this week.

I know -- it's that way for decent lawnmower batteries, too. Thanks; I'll check Academy.
