Ok folks... I'm going to ask a stupid question in a minute but cut me some slack
.
My experience with big battery banks has always been on crusing sailboats. I have 6 AGMs on mine now with all the goodies. I've been using AGM or Gels, for years. Never used lead acid on the boat as its just not a real safe alternative.
Just now got done putting in 4 Trojan T125's, hooked up my little inverter, installed the Trimetric Monitor, and cracked it all back up.
Everything is working great however my batteries are making a fair amount of bubbling noise. Sounds like club soda... or better yet - tonic water.
Right now my converter (Factory OEM unit) is on Bulk (absorb) mode so it's putting out 14.4v I'm going to assume that when it drops back down to 13.6 and then 13.1 they will quiet down but.....
My dumb question is.... how much noise do these suckers (lead acid batteries) make when charging at 14.4v? Is it normal to be able to hear them fizzing like that??
If so - another reason why you don't want them on a Cruising Sailboat - the battery bank is under a couch in the main cabin.
Other than that the install came out real nice. Got a plastic battery box that holds all 4 and put them up in the forward compartment. All the power posts, etc are in the same compartment and the inverter is on the other side of the wall in the basement.
When I ran the Trimetric wire up into the coach, I left a messenger string in place so when I upgrade and add panels, I'll have a line already in place to pull whatever wires, inverter controls or whatever i want to add on that wall.
