I have 16 for the identical electric batteries, and I also also experienced several of exactly what you will be explaining with unequal battery charging.
With my own, i understand they are sulfated to various levels, making sure that has triggered some of the imbalanced recharging voltages. I got myself my personal Lifelines at a low rates as «NEW», nevertheless they got seated for quite some time and had been deeply released before We ever have them. In addition wound up establishing my charge voltages at reduced conclusion of Lifeline’s guidelines, making sure that I wouldn’t overcharge some of the batteries.
Work okay for an emergency support battery pack system which rarely neeed, but they are not really everything I’d wish be determined by for daily off grid life. Some day, I hope receive a fresh pair of battery packs acquire off to the best beginning (and take very good care of all of them).
Re: 48 Volt power bank wiring
The following is Edward’s «keyturbocars» thread where he did a lot of investigation and screening a setup to recoup Lifeline AGM battery packs:
When the batteries in show (and match) were terribly mismatched (for example., good electric battery in show with sulphated power supply) might cause the unbalanced charging where one battery try recharging at «low current» and also the some other at «high voltage».
Charging/recovering electric batteries independently will help. Furthermore matching electric batteries by capacity («high» ability in one single string, «low» ability in the second collection sequence) will help also.
Re: 48 Volt electric battery lender wiring
I go along with Statement. Managing each battery pack independently may be beneficial. I did so they also it performed let my personal condition. Having said that, my personal electric batteries are so far gone to get started with your circumstance remains perhaps not great. Things are better though.
In case the power supply financial try newer and in best situation after that mine, subsequently trying to equalize each power individually per Lifeline’s therapy might supply good results.
Re: 48 Volt power supply lender wiring
Finally we checked the relaxing voltage they were within .01 https://besthookupwebsites.net/nl/sugardaddymeet-overzicht/ to .10 of every additional. (in fact my electric batteries never ever «rest»). Only examined (7:25 PM).. Neg area parallel battery packs at 12.75v, .07 to .10 higher than all other batteries with about a 150w to 200w load.
I got myself initial two batteries March ’10 additionally the last string of four in Oct ’10. (By the way, two of the chain had discharged battery packs (12.5 – 12.7). I becamen’t pleased to have actually settled that kinda funds for new electric batteries right after which need spend several days battery charging all of them before i possibly could use them).
On the whole, I’m ecstatic by using these little Lifeline batteries..
We have another lightweight 4-battery-12v-system of Costco wet cell electric batteries. Touch larger altogether amp many hours as compared to Lifelines but of course, they just can’t take much of a load for extended compared to the lifelines
Re: 48 Volt battery pack financial wiring
The electric batteries are (as they are) in a lot better shape than mine comprise. If memories acts myself best, i believe a number of my battery packs had been reading as low as 11.5V once I got them outside of the bins. They seated for 2 AGES before i purchased all of them. Other battery packs were higher, but they happened to be all over. They were all low!
I was thinking I became acquiring a good deal having to pay around 1/3 price (getting 3 for any cost of 1)!. Actually I found myself paying alot for scrap lead! UGH! Truly remarkable at how well they’ve got arrive around things deciding on, however they are not at all the things they ought to be. Eventually we propose to still do it. For now, they truly are adequate for just what I need.
Down the road, i would ike to become two chain on the 6V Lifeline GPL-6CT (large golf cart size) which are ranked at 300A/H each. This time, i will ensure they have been factory new and all of through the same lot. And that I’m going to heal all of them like they are created from GOLD!
Re: 48 Volt battery financial wiring
Many thanks and you will show David the design.
Re: 48 Volt power supply financial wiring
I’m not a fan of cross trapping battery packs of various strings. I favor to help keep each string as separate.
Crosstrapping will make it more difficult to identify a power supply going worst. In addition it has a larger potential for taking right out more close batteries as worst battery pack begins increasing the fee current on various other electric batteries. It is possible to juggle batteries around sometimes to suit upwards show linked current per battery pack and existing each string.
I’ve ten chain of four collection 12v battery packs (forty battery packs).
You will find 100 amp shunts on negative lead on each associated with the chain and watch each batteries voltage frequently. You will find a common 500 amp shunt for a trimetric monitor.
We have two parallel strings per cart (about 550 pounds per cart) with 350 amp Anderson connector for each of five carts. Carts take casters therefore it is easy to pulling the Anderson connector and roll an individual cart out for solution.
Each cart was 27″ longer, 24″ higher, and 15″ deep thus does not take too-much space from wall. Welded all five collectively, mostly from salvaged bed frame perspective iron.
Been working this config for about fifteen years. The 5th cart at much appropriate is an afterwards add-on and not matched up for cable size but There isn’t a lot current variance due to low-current per string making use of 2/0 interconnects.
