Hey maybe you can help me out please? I have one of the valence batteries like yours. I’ve had it for about 4 months and it’s been working fine. Until now. I have it installed in my truck, in the bed. It’s enclosed in a camper shell and weather tight. I charge it with a Renogy Rover 20 amp MPPT with two 100 watt panels. I have two fridge/freezer DC compressor coolers running 24/7. Usually I park my truck in it’s normal spot where it gets great sunlight daily and according to renogy software I get 60-70 ah a day. So everything should be fine. But recently we got our 2nd vehicle back from the shop and my wife took my parking spot. So Ive been parked in the shade. This morning I checked on my coolers and they weren’t running. My inline battery meter was showing 10.8 volts and the battery was blinking red every five seconds. I disconnected the load side of the battery and hit the road. I was in a hurry to get to the airport and didn’t have time to trouble shoot things. While driving I monitored the Rover and the battery voltage rose to 13v in about 45 minutes of 180watt charging from the Rover.
when I got home the battery was still blinking red with 13 volts and I started googling. I can’t find ANYTHING about the red LED accept for a different blink pattern. I’ve since removed the battery from the truck and it sits with an open circuit on my garage floor. I’ll note that it was hot today, about 103F.
Your post states low voltage red LED. Is my battery fried or just low? Any input would be greatly appreciated, thank you.
