I have 16 with the exact same batteries, and that I in addition skilled a number of just what you happen to be explaining with unequal battery-charging.
With mine, i am aware they are sulfated to various grade, in order that possess triggered many of the imbalanced charging you voltages. I bought my Lifelines at the lowest terms as «NEW», nonetheless they got sat for a long period and had been seriously released before I previously got them. I also ended up position my personal cost voltages on lower conclusion of Lifeline’s suggestions, to ensure that i mightn’t overcharge a number of the battery packs.
Functions okay for a crisis back up battery pack program that will be rarely neeed, however they are definitely not the things I’d need be determined by for daily off grid live. Some day, I’m hoping getting a fresh pair of batteries and obtain off to suitable beginning (and take good proper care of them).

Let me reveal Edward’s «keyturbocars» thread where he performed a lot of data and screening a set-up to recoup Lifeline AGM electric batteries:
When the electric batteries in show (and match) include very mismatched (for example., good power supply in collection with sulphated battery pack) may cause the unbalanced charging in which one power supply was recharging at «low voltage» while the some other at «high voltage».
Charging/recovering battery packs separately will help. Also coordinating electric batteries by capability («high» capability within one string, «low» capacity in the next series string) might help too.
Re: 48 Volt battery financial wiring
We accept Statement. Managing each power supply independently may be beneficial. I did it plus it performed let my personal situation. Nevertheless, my personal battery packs had been so far visited start with the situation is still perhaps not big. Things are much better though.
If for example the battery financial try more recent plus in better situation then mine, after that attempting to equalize each battery pack separately according to Lifeline’s procedure might supply accomplishment.

Last we checked the resting current they were within .01 to .10 of every additional. (Actually my personal batteries never «rest»). Only examined (7:25 PM).. Neg part match batteries at 12.75v, .07 to .10 raised above all the batteries with about a 150w to 200w burden.
I bought the most important two battery packs March ’10 therefore the final sequence of four in Oct ’10. (incidentally, a couple of strings have released battery packs (12.5 — 12.7). I happened to ben’t very happy to have actually settled that kinda revenue for new battery packs following need certainly to invest a few days charging you all of them before I could make use of them).
Overall, i am ecstatic with one of these little Lifeline batteries..
We have another tiny 4-battery-12v-system of Costco wet-cell electric batteries. Little larger altogether amp many hours than the Lifelines however, they just can’t simply take most of a load for very long when compared to lifelines
Re: 48 Volt battery bank wiring
Your own electric batteries are (and are also) in a lot better form than mine had been. If memory space acts me correct, i believe the my personal batteries were checking out as low as 11.5V while I got them out from the cardboard boxes. They sat for just two YEARS before i got myself them. Other electric batteries had been larger, nevertheless they were all around us. They were all very low!
I thought I was getting a great deal spending around 1/3 cost (getting 3 for your cost of 1)!. In fact I was having to pay much for scrap lead! UGH! It’s incredible at how good obtained are available around things considering, however they are definitely NOT whatever they should be. Someday I decide to still do it. For now, these include sufficient for what I wanted.
As time goes on, I’d like to become several strings associated with the 6V Lifeline GPL-6CT (large tennis cart proportions) which can be ranked at 300A/H each. This time around, I’m going to ensure they’re factory fresh as well as from the exact same good deal. And I also’m going to manage all of them as if they are produced from GOLD!

Many thanks and show David the drawing.
Re: 48 Volt battery lender wiring
I am not a fan of combination trapping electric batteries of various chain. I prefer to keep each sequence as separate.
Crosstrapping makes it more difficult to identify a battery pack going poor. In addition it have a higher chance for taking out fully more great electric batteries just like the bad electric battery starts elevating the cost voltage on various other battery packs. Possible juggle battery packs around sometimes to match right up series connected current per power and existing for each string.
I have ten chain of four show 12v electric batteries (forty electric batteries).
I’ve 100 amp shunts on unfavorable lead on each on the strings and watch each electric batteries current on a regular basis. We have one common 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 for every single from the five carts. Carts are on casters so it’s an easy task to pulling the Anderson connector and roll a single cart for solution.
Each cart is actually 27″ longer, 24″ large, and 15″ deep very does not take excessive place from wall. Welded all five with each other, mostly from salvaged bedframe angle metal.
Been operating this config approximately fifteen years. The 5th cart at far appropriate was actually an afterwards increase and not paired for wire size but I don’t have much current difference because of low current per string making use of 2/0 interconnects.
