Battery Indicator Lights

[arizonaangler]

Does anyone have any idea where I can find a battery level indicator light for my trolling motor? I have a new boat, new batteries and new motor, but I still will feel better if I know how much "juice" is in my batteries while I'm on the water. I'd hate to get stranded.

I saw one at the sports authority in exton but that was a while ago.

Bass Pro Shops has a portable battery gauge for $25. Saw it in the catalog last night when I was looking for a charger.
