Very nice!  One thing though, I would charge them individually initially to determine the health of the individual battery, if bad you can eliminate that one.  When charged in the bank of three like that you are only as good as the weekest link.  Once you know the health of the individual batteries then you can charge them together to determine what the proper average voltage you are going to have.

06 May 14:  Topic was merged with original and moved to 'General" for continuity.  (NO, not THAT kind of 'continuity'... you don't need a multi-meter to read this thread...:)

thanks PG, was looking for a way to do that.

 

the bank of 3 turned over today,going to leave on float till Friday night   at that time I will separate them and let stand overnight then take individual voltages in the morning.

on the bad one it came up but next morning it was at 7V so I think it safe to say that one is a goner.

You're welcome, John... I figured you wanted them all together in one place.   It's easier to follow this way...

 

Best of luck on your project.

one of the 3 batteries I set up is weak but holing ~12.5V after 2 days off the charger. the other 2 are 13.2V so I'll call them good. I took the one that dropped off like a rock on the float charger to see how that goes. next week I'll deal w/the last bad one then go from there.

shot a couple of vids today but haven't had a chance to review them yet. took elevation reading also today,where the antenna currently sits is 1095' , where its going is 1210' roughly and the entrance to my driveway is 1066'. maps were made to accommodate a couple of different gain antennas and different heights. they all came out roughly the same height being the bigger factor. right now I have no plans to purchase any antennas and just use what I have around.

2 older PD 201's

1 Antennex 4607

plan on using the 201's as it is a better performer than the other.

the one bad battery went into float and has settled out at 12.8 V, we'll see what that looks like in a week. in the mean time I put the second bad one on the float and it came up rather quickly but no float yet. checked the standing voltages of the 3 I had done 2 weeks ago and no change in voltages, this is a good thing. going to top off the low one and see if it stays were the others are.

may do some more testing over the long weekend if I can manage to borrow an extension ladder and get it up to the site. "if" that works out I will put it up temporarily on my small gen set and go do some field testing. this should give me  a rough clue as to what I can expect out of it. must remember to bring enough cable w/me.

and on a side note I'm rethinking the size of the shack to 8'x8' as 4'x8' just seems a little tight when I laid it out in my garage today.

did not have a chance to do anything this weekend on the site.

on a related note came across a new to me antenna co. that we bought from last week. they seem to be well built and not too bad price wise. I may get one to put on my 575 just to see how well it performs against what I'm using now once an account is set up. have heard good thing from a couple of people about them.

leaning towards the second one.

might be able to pull AC out to it w/o too much line loss.

was at a job site talking w/some electricians and one posed an interesting idea............... step up to 480 then down to 120 therefore reducing how fat a wire I need to go as far as I do.

must research this further, going to keep the batteries though. have to have a BU.

Hopefully, that's not a body laying in the brush just below the ladder..... ;) :D

Love the pic's. I am just getting caught up, is that a 25-40 foot ladder? next to a 50' telescoping mast? I am guessing but those trees look to be over 100', like I said have not been on in a wile. are you planning a tower? or plan to mount the mast in the top of the tree? very exciting. and yes if you step the voltage up to 480V you can run a super long run on much smaller gage wire with little loss. They do it in modern solar installations, step up to 400V DC and they can go from AWG1 to AWG10 and save several thousands on copper.  If you built a tree house you would have an awesome shack. Wish I could help.

the mast is 30' w an 8' antenna on it, that was the "test" set up. I really don't remember how big the ladder was and it wasn't all the way up.

my best guess is its about 70'. once I get in it I have a 100 foot tape measure I'm going to drop and see what it is.

there were a few other things but thats the major stuff. will have to get some EMT or galvanized pipe for the cable to go into on the ground so it doesn't get beat up

anyone else have any thoughts.
