I have 16 with the identical electric batteries, and that I furthermore practiced several of precisely what you’re explaining with unequal battery charging.
With mine, i am aware that they are sulfated to various degrees, so that have caused many imbalanced battery charging voltages. I bought my personal Lifelines at a reduced costs as ”NEW”, but they had sat for a long time and are profoundly released before I previously have them. I also ended up place my cost voltages on lowest conclusion of Lifeline’s referrals, so that i mightn’t overcharge many battery packs.
Works okay for an emergency support battery system definitely seldom neeed, however they are not really the things I’d wanna rely on for each day off grid dwelling. Some day, i am hoping to get a brand new pair of batteries and get to suitable start (and get very good proper care of all of them).
Re: 48 Volt battery lender wiring
We have found Edward’s ”keyturbocars” thread where he performed a lot of research and screening a setup to recuperate Lifeline AGM battery packs:
In the event the electric batteries in series (and match) is terribly mismatched (i.e., close battery in series with sulphated power) may cause the unbalanced charging where one power supply is asking at ”low current” and also the different at ”high voltage”.
Charging/recovering batteries separately will help. Additionally complimentary batteries by capacity (”high” ability in one string, ”low” capacity in a second collection sequence) can help also.
Re: 48 Volt battery pack financial wiring
We accept Statement. Managing each power supply independently may be beneficial. I did so it plus it performed help my situation. However, my electric batteries happened to be up until now visited start out with the circumstances continues to be perhaps not fantastic. Things are much better though.
Should your power lender are new along with best state subsequently mine, after that attempting to equalize each power separately according to Lifeline’s procedure might give you great outcomes.
Re: 48 Volt power financial wiring
Finally I examined the resting current these people were within .01 to .10 of every additional. (really my batteries never ever ”rest”). Only inspected (7:25 PM).. Neg area match electric batteries at 12.75v, .07 to .10 higher than other electric batteries approximately a 150w to 200w weight.
I bought the first two batteries March ’10 and last string of four in Oct ’10. (incidentally, a couple of strings got discharged batteries (12.5 – 12.7). I wasn’t happy to have settled that kinda revenue for new electric batteries after which need invest several days battery charging all of them before I could make use of them).
On the whole, I’m ecstatic using these little Lifeline electric batteries..
You https://www.besthookupwebsites.net/nl/parship-overzicht/ will find another lightweight 4-battery-12v-system of Costco wet cell battery packs. Little greater overall amp many hours as compared to Lifelines but of course, they simply are unable to just take most of a lot for extended set alongside the lifelines
Re: 48 Volt electric battery lender wiring
Your batteries were (and are also) in definitely better form than my own happened to be. If memories acts me appropriate, I think the my personal batteries were checking out only 11.5V whenever I got all of them from the cartons. They seated for 2 YEARS before i got myself them. More electric batteries comprise greater, but they had been all over the place. They certainly were all really low!
I was thinking I became acquiring much paying around 1/3 rates (acquiring 3 for any cost of 1)!. In reality I happened to be having to pay many for scrap lead! UGH! Truly remarkable at how good they usually have are available around all things looking at, however they are not whatever should really be. One day I want to do it right. For now, they’ve been enough for what i would like.
In the foreseeable future, let me become one or two chain associated with 6V Lifeline GPL-6CT (oversized golf cart proportions) that are ranked at 300A/H each. This time around, i will ensure that they truly are factory new and all from same great deal. And I also’m probably treat all of them like they are made from SILVER!

Thank you and you may reveal David the drawing.
Re: 48 Volt power financial wiring
I am not a fan of cross trapping batteries of various chain. I favor keeping each string as separate.
Crosstrapping helps it be more difficult to recognize a battery pack going terrible. Additionally have a better probability of taking right out extra great electric batteries since terrible electric battery initiate increasing the cost current on different electric batteries. You can easily juggle battery packs around sometimes to match right up show linked voltage per electric battery and recent for every single sequence.
I’ve ten chain of four collection 12v batteries (forty electric batteries).
I have 100 amp shunts on adverse contribute on each associated with the chain and keep track of each electric batteries current on a regular basis. We have a standard 500 amp shunt for a trimetric monitor.
You will find two parallel chain per cart (about 550 lbs per cart) with 350 amp Anderson connector each on the five carts. Carts are on casters it is therefore very easy to move the Anderson connector and move one cart away for provider.
Each cart are 27″ very long, 24″ high, and 15″ rich thus does not occupy an excessive amount of place from wall. Welded all five collectively, generally from salvaged bed frame angle metal.
Been run this config for around fifteen years. The fifth cart at far appropriate is a later on increase rather than matched for cable length but I don’t have a lot current variance considering low current per sequence utilizing 2/0 interconnects.
