RE: Charger: Meanwell 10a or Iota DLS 15?

Niner, if my Iota proves to be defective, I may replace it with that 80A MegaWatt unit. I'll buy another converter when I sell the rig. If I go that route I'll post a thread with some questions (I've never start to finish manually charged my batts before always used the converter first).

RE: when should a powermax pm4b drop into float mode

understood, but is it o.k. to just let the batteries decide on the amps at the beginning of E, or should they be kept limited to say 4amps? thanxx! (the main reason i ask, is i need to make a decision on whether i need a power supply with adjustable amps?)See MEX's post. Try it out first though.

RE: when should a powermax pm4b drop into float mode

Great way to equalize because no babysitting, you can let it run overnight while you sleep :) The classic method with a manual charger means you have to be there and shut it down yourself before it overdoes it. Sometimes to get the SG back to baseline I have to run two Es in a row with the VEC. Get the first FUL then restart and do another E and it will run for more time with amps tapering till says FUL again. I use the VEC when I don't have time but with the power supply, it takes a LOT less time because of the much higher amps so I probably won't use the VEC anymore for that. Mine starts at 24A and tapers to 9 and holds there (the taper is probably much slower by then). It seems that once it gets to the "holding" amps, the SG is where it should be at that point. I need to use it more to verify. Finish charging would probably take 30 mins on your bank BFL.

RE: Why should I switch to golf cart 6v batteries

Oh come on, you'd be lost without being able to dip your hydrometer with those new fangled batteries.Just saw this! Believe me I would not miss it! LOL

RE: Why should I switch to golf cart 6v batteries

I do wonder how long before Lifepo4 becomes affordable. No peukert, no worrying about partial discharge storage, ability to accept insane charging currents, support huge loads. No more 6v vs 12v threads..........You can use 80% of LI capacity (less than that and you're down the curve on cycle life) and still get more than double the cycle life of lead acid. Lots of people are running 2 6V at 232Ah. A single 160Ah 12V LI batt would give them a bit more usable capacity than the 6V's plus you can run a microwave from them at low SOC's without massive voltage sag and Peukert. That website that PT linked has 160Ah "cells" for $170 each, so $680 for a "12V" batt. You can get an inexpensive BMS from HERE which covers cell balancing, high and low voltage cutoffs, and some other stuff. That will probably cost around $100. Then there is copper bus bars, and some strapping to hold the cells together. If you're gonna go this route, read, read, read then read some more.

RE: Why should I switch to golf cart 6v batteries

The price is good. Considering 100% usable charge, this is $2/AH. My cheap AGM was $1.80, other AGM are $2-$3/AH.I just might be able to pick these up next go around. Just think a single battery with more usable capacity and longer life than my 4 L16's. Yeah it's still double the price of those L16's but none of the downsides.

RE: Converter vs Battery charger

Want to learn from others? Look up Landyacht318's thread "My screwy 31's." Text book learning process, that we all go through.That is a great thread, tons of info there.

RE: when should a powermax pm4b drop into float mode

The VEC has its uses but the Meanwell (BTW I bought mine from the same place that Niner got his) is great in that you can control the voltage and let the batteries acceptance pick the amps. IMO, if you don't have a VEC, the Meanwell will more than do that job and it works in very hot climates too (I've had mine running 24/7 in 108+F/42+C).

RE: Converter vs Battery charger

Do you start out with the mega watt at 15v? What do you suggest?There's an adjustable pot on the MW. Turn as needed but it's really sensitive.

RE: Why should I switch to golf cart 6v batteries

Hi, If you have deep pockets...four X $700.00 for 700 amp-hours http://www.balqon.com/wp-content/uploads/2013/11/wb-lyp700ahalp.jpgThose have come down quite a bit in price. I remember when I was looking 400Ah was about that much. In 5-6 years maybe. Probably 4*700, no? Also, trying to figure out AH rating. There is no 20hr AH number. Instead it says "Max Discharge < 3 CA Peak | <700 amp continous".It says 700Ah in the title and going by the picture, it looks like a 700Ah "cell" (I have a spec sheet on that battery). You'll to wire 4 of those in series to get a "12V" battery. You'll also need a battery management system as those are bare cells.

RE: when should a powermax pm4b drop into float mode

one of them made the comment that ALL converters are crappyMy work is done here! :) To the OP, you can take a set of 6V's down below 50% SOC. That's not a hard wall. There's a member here that does this routinely with his Trojan T105's and I've done it myself a few times on the pig out weekends. Yes there is less life doing it that way but not enough for us RVers to notice IMO. Now if you're a fulltimer that lives off grid like MrWiz, I don't recommend doing that. I also don't recommend doing that until you understand your batteries and what it takes to maintain them.

RE: when should a powermax pm4b drop into float mode

Start studying, read, reread, recalculate, and ask questions, until you are convinced that you have figured out the fallacy known as "charge controllers" on your rig, and received some facts, truth and guidance in the BS world of RV charge controllers. Being off the grid changes everything ,as far as charging requierments, as the industry knows it in the RV world.Let the church say amen! :B

RE: Am I shortening my battery life?

Go Power 600W PSW is my recommendation. CLICKY

RE: when should a powermax pm4b drop into float mode

Here's the power supply MEX is talking about. CLICKY The 30 or 36 amp will do. I have the 30 amp one that I use for floating mostly cause my IOTA currently won't run in hot temps (troubleshooting in progress).

RE: when should a powermax pm4b drop into float mode

X2 MEX. My converter will go all the way to 0 amps and the batteries are still not full. Converters don't fully charge batteries. None of them do (I've used 3 different one's).
