I do want to evaluate my charging. Bought two 6v from costco in Feb. Plan was to invest in a better solar charger before installing on the trailer. I skimmed around the trojan pages and watched their series of videos on youtube. Its the one with the lady who goes over charging and testing.
It left me thinking that for my situation of being on shore power mostly why the heck would i want to charge them everyday? With summer coming i thought about storing the batteries in the garage and manually charging them. Or another plan was use foam board to insulate my battery boxes a bit. Goal is to keep temps down. No need to roast my batteries as they sit there unused.
Now im leaning more towards keeping my original solar controller and hooking up a disconnect switch. A couple times a month i could flip to battery power and drain them down to say 80%. Then flip on the solar for a day or two.
But doing that is not the big powerful amp charge i want for 6v flooded right? I tried to measure my converter yesterday. I turned on lights for about an hour to drain the batteries a little. Was only a 6.5a load.
Then i plugged in the trailer and my wyco (?) converter put out 17amps i think. Somewhere around 14-17a i cant remember now. I had the monitor hooked up and the charger never went to 14+ volts.
Is that because the charger sucks, or because i didnt discharge enough and the charger went more for a float charge?
My solar would show 14.4v every morning. I swear once or twice i saw it show 14.8v. Which i learned is what i want for flooded charge. I do have a manual charger that i could make do an equalization charge if i decide to keep my cheapo solar controller as my main charge source.
Below is a graph. Yesterday i charged the 6v using a harbor freight charger in the garage. THe second part of the graph is my 12v batteries being charged by the converter.
