I’ve 16 of same battery packs, and I also additionally practiced some of precisely what you may be describing with unequal battery-charging.
With mine, i understand that they are sulfated to different qualifications, so provides brought about a number of the imbalanced asking voltages. I purchased my personal Lifelines at the lowest terms as „NEW“, nonetheless had seated for a long period and happened to be significantly discharged before I ever have them. I additionally wound up place my cost voltages at the lower end of Lifeline’s guidelines, so I wouldn’t overcharge some of the battery packs.
Functions OK for an emergency support battery system this is certainly seldom neeed, but they are not the things I’d like to depend on for daily off grid living. Some day, i really hope getting a new pair of battery packs acquire to the best beginning (and just take very good care of all of them).
Re: 48 Volt electric battery financial wiring
Let me reveal Edward’s „keyturbocars“ thread where he did a number of analysis and testing a create to recoup Lifeline AGM battery packs:
In the event that electric batteries in series (and parallel) become awfully mismatched (in other words., good power supply https://besthookupwebsites.net/nl/romancetale-overzicht/ in show with sulphated power) may cause the unbalanced charging where one power try charging you at „low current“ therefore the additional at „high current“.
Charging/recovering electric batteries individually may help. Furthermore coordinating electric batteries by capacity („high“ capacity in a single sequence, „low“ capacity in an additional collection sequence) may help too.
Re: 48 Volt battery pack financial wiring
We trust Expenses. Handling each power separately is a good idea. I did they plus it did help my personal scenario. Even so, my batteries had been to date visited start the condition continues to be maybe not great. Everything is best though.
When your power supply bank was new plus in much better situation after that mine, after that wanting to equalize each battery pack individually in accordance with Lifeline’s therapy might supply good results.
Re: 48 Volt power financial wiring
Final I inspected the relaxing current these people were within .01 to .10 of each some other. (Actually my batteries never ever „rest“). Merely examined (7:25 PM).. Neg part parallel electric batteries at 12.75v, .07 to .10 greater than all the battery packs approximately a 150w to 200w load.
I purchased one two electric batteries March ’10 therefore the final sequence of four in Oct ’10. (by-the-way, two of the chain have discharged batteries (12.5 – 12.7). I wasn’t happy to has settled that kinda cash for new battery packs and must spend several days recharging them before i really could make use of them).
On the whole, I’m ecstatic by using these little Lifeline batteries..
I have another smaller 4-battery-12v-system of Costco wet-cell batteries. Little bit greater as a whole amp time as compared to Lifelines but of course, they just can not capture a lot of lots for extended when compared to lifelines
Re: 48 Volt power bank wiring
Your batteries comprise (and so are) in far better profile than mine are. If memory acts myself right, In my opinion a number of my personal batteries are checking out only 11.5V as I grabbed them outside of the bins. They seated for just two AGE before I bought them. Various other battery packs comprise larger, even so they were all over. These were all low!
I was thinking I became obtaining much having to pay around 1/3 rates (obtaining 3 for cost of 1)!. In actuality I became paying plenty for scrap contribute! UGH! Truly incredible at how well they usually have come around all things thinking about, however they are not really whatever they should be. Someday we intend to do it right. For now, they truly are sufficient for just what I need.
Later on, I want to bring a couple strings in the 6V Lifeline GPL-6CT (large tennis cart size) that are ranked at 300A/H each. This time, I’m going to be sure that they truly are factory fresh and all of through the exact same lot. And I’m probably address them as if they are created from GOLD!

Cheers and reveal David the design.
Re: 48 Volt battery pack lender wiring
I am not saying keen on cross trapping electric batteries of different chain. I like to help keep each sequence as separate.
Crosstrapping will make it more challenging to recognize an electric battery going poor. Moreover it features a better chance for taking out more good batteries while the terrible power supply begins elevating the charge voltage on various other battery packs. You’ll be able to juggle electric batteries around sometimes to complement right up collection connected voltage per power supply and existing each sequence.
I’ve ten strings of four collection 12v battery packs (forty batteries).
We have 100 amp shunts on negative contribute for each of strings and keep track of each battery packs voltage on a regular basis. You will find a typical 500 amp shunt for a trimetric track.
You will find two parallel strings per cart (about 550 pounds per cart) with 350 amp Anderson connector for each and every from the five carts. Carts take casters making it an easy task to extract the Anderson connector and roll an individual cart around for provider.
Each cart is actually 27″ lengthy, 24″ large, and 15″ rich so does not use way too much room from wall structure. Welded all five collectively, mostly from salvaged bed frame angle metal.
Become working this config for approximately fifteen years. The fifth cart at far appropriate had been an after increase rather than matched up for wire length but I don’t have a lot current difference as a result of low-current per sequence making use of 2/0 interconnects.
