I’ve 16 regarding the identical electric batteries, and I also practiced a number of exactly what you happen to be explaining with unequal battery-charging.
With mine, I’m sure they are sulfated to various levels, to ensure that enjoys triggered many imbalanced charging voltages. I bought my Lifelines at a decreased costs as “NEW”, however they have seated for a long period and are profoundly discharged before We previously have all of them. I additionally ended up setting my cost voltages during the lower end of Lifeline’s referrals, to make certain that i mightn’t overcharge many batteries.
Really works okay for an emergency back-up electric battery system which rarely neeed, however they are not at all the thing I’d wish to depend on for each day off grid living. Some day, i am hoping receive a fresh group of battery packs and obtain off to the best start (and grab good proper care of all of them).
Re: 48 Volt power financial wiring
Let me reveal Edward’s “keyturbocars” thread in which the guy did a lot of study and testing a setup to recover Lifeline AGM battery packs:
If the batteries in collection (and parallel) are awfully mismatched (in other words., good power in series with sulphated power) might lead to the unbalanced charging in which one battery pack try battery charging at “low current” in addition to different at “high current”.
Charging/recovering electric batteries independently may help. Furthermore matching electric batteries by capability (“high” capability within one string, “low” capability in the second show string) might help too.
Re: 48 Volt electric battery bank wiring
We agree with Costs. Managing each power individually is a great idea. Used to do it and it performed assist my personal condition. But, my batteries had been so far visited begin with that circumstance continues to be perhaps not fantastic. Everything is best though.
If your power bank try more recent and also in best state next mine, then attempting to equalize each power supply individually based on Lifeline’s procedure might supply good results.
Re: 48 Volt battery pack bank wiring
Last we checked the sleeping voltage these were within .01 to .10 of each additional. (Actually my electric batteries never “rest”). Simply examined (7:25 PM).. Neg side parallel electric batteries at 12.75v, .07 to .10 greater than all the other batteries with about a 150w to 200w weight.
I bought the initial two batteries March ’10 therefore the last string of four in Oct ’10. (incidentally, a couple of chain had discharged battery packs (12.5 – 12.7). I wasn’t thrilled to bring compensated that kinda money for new electric batteries and need to invest several days charging all of them before I could make use of them).
On the whole, i am pretty happy with these little Lifeline battery packs..
I’ve another tiny 4-battery-12v-system of Costco wet-cell batteries. Small bit greater altogether amp many hours compared to the Lifelines however, they just are unable to take a lot of a load for very long set alongside the lifelines
Re: 48 Volt electric battery financial wiring
The battery packs had been (and are) in much better shape than my own happened to be. If memories serves myself correct, I think a number of my personal battery packs had been is bdsm gratis reading as low as 11.5V while I grabbed all of them out from the cartons. They sat for 2 DECADES before i purchased them. Some other batteries happened to be larger, however they happened to be all over. They were all really low!
I was thinking I was obtaining a great deal spending around 1/3 rate (obtaining 3 the price of 1)!. The truth is I was having to pay a large amount for scrap contribute! UGH! Truly remarkable at how well they will have arrive around everything looking at, however they are not at all what they should always be. Someday I propose to do it right. For the present time, they truly are sufficient for just what I wanted.
Someday, i would ike to have two strings with the 6V Lifeline GPL-6CT (oversized golf cart size) which happen to be ranked at 300A/H each. Now, i will make sure that they’re factory fresh and all from the same great deal. And I also’m browsing heal them as if they are made of SILVER!

Thank you and showcase David the design.
Re: 48 Volt battery bank wiring
I’m not a fan of cross trapping battery packs of various strings. I like keeping each string as separate.
Crosstrapping causes it to be difficult to recognize a power supply heading terrible. Additionally, it possess a greater chance of taking out fully a lot more good electric batteries as bad electric battery starts elevating the fee current on different electric batteries. You can easily juggle batteries around sometimes to match upwards series connected voltage per power and present for every single string.
I’ve ten chain of four series 12v electric batteries (forty electric batteries).
I have 100 amp shunts on negative contribute on every associated with the chain and watch each electric batteries voltage regularly. I have a standard 500 amp shunt for a trimetric watch.
I’ve two synchronous chain per cart (about 550 lbs per cart) with 350 amp Anderson connector for each of five carts. Carts are on casters it is therefore simple to move the Anderson connector and move just one cart out for solution.
Each cart try 27″ long, 24″ high, and 15″ deep so does not take extreme space from wall surface. Welded all five with each other, generally from salvaged bedframe angle iron.
Become working this config for around fifteen years. The fifth cart at far best was actually a later add-on rather than matched up for cable size but I don’t have a lot current variance as a result of low current per string making use of 2/0 interconnects.
