Like I said ists for a model boat.12v7ah sealed lead acid battery. I would like to have 2 leds,red and green. I'm scared of taking the boat out with a flat battery and then ill have to swim very far to get it. So if the red led is on I know not to take it out. There must be someone on here that has attempted or build something similar.
You left sealed lead acid battery off your orginal post. Volt meters are a dime a dozen. Look at the LM3914 many of the kits use this chip. AndyLike I said ists for a model boat.12v7ah sealed lead acid battery.
Yup the LM3914 can do that. look up the data sheet. AndyWhat I'm looking 4 is ... If the voltage drop to 10.4v then the red light should come on. The motor runs @ constant 3500rpm. Is a bait fishing boat. So the notor will be on or off.
Hello,
If it drops that low it's too late to do anything about it![]()
Kiss the battery "goodbye" then deliver it to a battery disposal center.If it drops that low it's too late to do anything about it![]()

I had a heart attack but they fixed it. Now I am almost like new. Not like a dead battery.
That's why I told him to set the detector to go off when the battery reaches ~11.5V
I am glad I had a heart attack at home because I was rushed to the nearby hospital very quickly for the repair of the blocked arteries that feed my heart.Sorry to hear about the heart attack. I've been taking aspirin so hope that helps. I've read it helps post HA victims too.
