shouldn't let your battery get below 50%. love my trimetric battery monitor, allways know exactly where my battery is. showes draw as low as.o1 amp. 2 6 v 132ah interstate, 200w fixed solar, 2oow portable can runin parallel

I have a 2017 Forrest River Ultra Lite 34' and the 2nd time out it got cold so of course the heater turned on at 2 or 3 in the morning. By the 2nd time the heater turned on the beeper was going the rest of the night even though my battery indicator was on 2/3 power. My trailer came with dual deep cycle batteries from interstate. The service guy at the dealer said to have the batteries checked by interstate so I did. They were fine. I don't understand the low voltage warning at all and maybe someone could explain a bit better as to why I cant get a co/LP detector and mount it right next to the one I have and why I cant just disconnect that damned beeper. My old trailer also had a heater but with one battery never had a problem if the battery was dead in the morning I just started the generator and recharged it. Are they just way over engineering this stuff today because there are really really stupid people or what would the reasoning be i cant run my heater on battery power, litterally ever. I start the generator every day and fully charge the batteries and I don't see why that stupid thing starts beeping with the battery indicator still showing 2/3 charge.

Seeing how much you can conserve is a good thing, but boondocking without a monitor is kind of like driving your car without a gas gauge. I recommend Trimetric TM-2030 but there are others that I am not familiar with. They run about $165 and you will need a Shunt wired in properly.

Most people run out of battery during the night simply because they start the evening with nearly dead battery (batteries).

Strange that the only way you know your batteries are critically low is when the CO detector is warning you to do something. I have heard of people that when their interior lights get too low to read by, then they do something.

That factory monitor panel... especially the battery indicator, is a "guess" gauge; kind of an idiot light that reads full when its not and low when its too late. When reading low you have already greatly diminished the life of batteries, at best. If you can afford batteries every year and don't mind running out during the night; and don't mind that a CO detector beeping, then don't get a good battery monitor and just keep guessing. That is what I used to do, but learned how to take care of my batteries, I went fairly low dollar on them, but I still can't afford $500 every year or two for new ones.

I have four GC-2 at 460 amp/hour (230 usable) and a 100 amp charger, not to mention a Honda 2000 that I use to charge when needed.... Oh, and 450 watts of solar. For my needs this is an economical setup and a bare minimum.

The furnace is a huge current drain and the batteries are probably lower than you think. As mentioned, the panel lights are unreliable. A voltage reading, while not perfect, will be closer to the truth.

I think nodrawers makes a good point. I have the same problem with the idiot beeper. Here's a thought - maybe I just don't care if my batteries are low. I cannot image a detector that can and should run off of a tiny 9v battery for at least six months, connected to two 12v house batteries with what 90Ah each, triggering an alarm.

The draw should be so minimal on this detector that I should never hear it until it is absolutely on its last amps. Adding more batteries, solar panels, generators and plugging in seems ridiculously like overkill just to deal with a greedy monitor.

I think it draws too much for a 9 volt. Seems like I measured .2 - .3 amps but might have included the load center. I wonder what voltage it sees when beeping starts?

Home Depot carries a battery-powered dual CO/Gas detector for $49. Guess what I'm getting for Christmas?

Trimetrics are nice but expensive...

My Xantrex Pro-Sine gas that (low voltage) feature builr in and notifies me when the threshold voltage drops below 11 volts.

It's not visual but I sure can hear the alarm. Nice thing is, it works whether the inverter is running or just on standby.

..........and audible gas gauge... lol
