What age are their Lifeline Concorde electric batteries? Just like you described.

You will find 16 from the very same batteries, and I also furthermore skilled a number of precisely what you are describing with unequal battery charging.

With my own, I know that they’re sulfated to different levels, to make certain that features triggered a number of the imbalanced asking voltages. I got myself my Lifelines at a decreased cost as “NEW”, even so they have seated for quite some time and happened to be significantly discharged before We ever before got them. In addition finished up place my cost voltages at the reduced conclusion of Lifeline’s recommendations, to make certain that I wouldn’t overcharge some of the battery packs.

Performs OK for an emergency back-up power supply program this is certainly rarely neeed, but they are not the thing I’d should depend on for each day off grid live. Some day, i really hope to get a new group of electric batteries acquire to the best start (and take good care of them).

Re: 48 Volt battery pack lender wiring

Is Edward’s “keyturbocars” thread in which the guy did a number of analysis and testing a set-up to recoup Lifeline AGM electric batteries:

If batteries in collection (and parallel) is awfully mismatched (i.e., great swingstown battery pack in collection with sulphated power supply) may cause the unbalanced charging in which one electric battery was asking at “low current” therefore the different at “high voltage”.

Charging/recovering electric batteries separately can help. In addition matching battery packs by capacity (“high” ability in a single sequence, “low” capacity in another show sequence) can help as well.

We trust Bill. Managing each power independently is a great idea. I did they and it also did assist my personal scenario. Even so, my personal battery packs are so far attended start that condition is still maybe not fantastic. Things are best however.

If for example the battery pack bank are more recent plus in better condition next mine, subsequently wanting to equalize each battery separately according to Lifeline’s process might supply great outcomes.

Re: 48 Volt power supply financial wiring

Last I checked the sleeping current they were within .01 to .10 of every other. (really my personal battery packs never ever “rest”). Simply examined (7:25 PM).. Neg area parallel batteries at 12.75v, .07 to .10 higher than all the other batteries with about a 150w to 200w load.

I purchased initial two battery packs March ’10 and also the final sequence of four in Oct ’10. (in addition, a couple of chain had discharged electric batteries (12.5 – 12.7). I becamen’t very happy to has paid that kinda cash for brand new batteries immediately after which need spend several days charging you them before i really could utilize them).

All in all, I’m ecstatic with these small Lifeline batteries..

I have another smaller 4-battery-12v-system of Costco wet cell electric batteries. Small bit larger altogether amp time compared to the Lifelines but of course, they simply can not just take the majority of lots for lengthy set alongside the lifelines

Re: 48 Volt battery pack bank wiring

Your electric batteries are (and they are) in definitely better form than my own comprise. If memory serves me personally best, In my opinion the my electric batteries were checking out only 11.5V once I grabbed them out of the boxes. They seated for 2 AGES before i purchased all of them. More battery packs are higher, even so they are all around us. These people were all low!

I thought I happened to be obtaining a good deal having to pay around 1/3 price (getting 3 for any cost of 1)!. In reality I became having to pay a great deal for scrap contribute! UGH! Really remarkable at how well they will have arrive around all things thinking about, however they are not really what they must certanly be. One day we plan to still do it. For now, they’re enough for just what Now I need.

Down the road, I’d like to get several chain of the 6V Lifeline GPL-6CT (oversized golf cart dimensions) which can be rated at 300A/H each. This time, I’m going to make sure that these are generally factory fresh and all of from same good deal. And I also’m likely to treat all of them like they are made of GOLD!

Cheers and program David the design.

Re: 48 Volt battery bank wiring

I’m not keen on mix trapping battery packs of various strings. I prefer to keep each string as separate.

Crosstrapping causes it to be difficult to identify a battery pack heading worst. In addition it enjoys a better chance for taking out most good electric batteries since the worst power begins elevating the cost voltage on various other batteries. Possible juggle electric batteries around often to match right up show linked current per electric battery and latest each sequence.

We have ten chain of four collection 12v electric batteries (forty battery packs).

I’ve 100 amp shunts on negative lead on each for the strings and track each battery packs current frequently. I’ve a standard 500 amp shunt for a trimetric monitor.

You will find two parallel chain per cart (about 550 pounds per cart) with 350 amp Anderson connector per in the five carts. Carts take casters making it very easy to extract the Anderson connector and move a single cart on for service.

Each cart is actually 27″ very long, 24″ large, and 15″ rich therefore doesn’t take up too much room from wall structure. Welded all five together, primarily from salvaged bedframe angle iron.

Been running this config approximately 15 years. The fifth cart at much correct is an after add-on and never matched up for wire duration but I don’t have a lot voltage variance as a result of low current per string making use of 2/0 interconnects.
