What age become the Lifeline Concorde batteries? Like everyone else outlined.

We have 16 associated with the exact same electric batteries, and that I also skilled several of just what actually you’re explaining with unequal battery charging.

With my own, I know that they’re sulfated to several degrees, so has triggered a few of the imbalanced battery charging voltages. I got myself my personal Lifelines at a decreased rates as “NEW”, however they had sat for quite some time and are seriously released before I actually ever got them. I also ended up setting my personal charge voltages during the reasonable conclusion of Lifeline’s tips, with the intention that i mightn’t overcharge many of the batteries.

Performs OK for a crisis support battery program which rarely neeed, however they are not at all everything I’d desire to depend on for daily off grid lifestyle. Some day, i really hope to have a fresh group of electric batteries and acquire off to the right begin (and take good care of all of them).

Re: 48 Volt battery bank wiring

Is Edward’s “keyturbocars” thread where he did a bunch of analysis and evaluating a setup to recover Lifeline AGM battery packs:

If electric batteries in collection (and parallel) tend to be terribly mismatched (for example., close battery pack in series with sulphated electric battery) might lead to the unbalanced charging where one power supply was charging at “low current” and other at “high voltage”.

Charging/recovering batteries independently might help. Additionally matching battery packs by ability (“high” ability in one single string, “low” ability in a second series sequence) might help too.

Re: 48 Volt power financial wiring

We go along with Statement. Handling each electric battery separately is a great idea. I did it also it did help my personal condition. Even so, my personal electric batteries were so far gone to begin with the situation remains not great. Things are better though.

In the event the power financial is newer and also in better situation then mine, subsequently attempting to equalize each electric battery independently per Lifeline’s process might supply great outcomes.

Re: 48 Volt power supply lender wiring

Last I checked the sleeping voltage they certainly were within .01 to .10 of every additional. (in fact my batteries never “rest”). Simply inspected (7:25 PM).. Neg part match electric batteries at 12.75v, .07 to .10 greater than all the other electric batteries with about a 150w to 200w weight.

I bought the initial two battery packs March ’10 while the finally string of four in Oct ’10. (by-the-way, a couple of chain had discharged battery packs (12.5 – 12.7). I wasn’t thrilled to have actually paid that kinda revenue for new battery packs and need to spend a few days charging all of them before i really could utilize them).

In general, i am pretty happy by using these little Lifeline batteries..

I have another little 4-battery-12v-system of Costco wet-cell battery packs. Tiny bit higher in total amp time than the Lifelines but of course, they simply can not just take a lot of a load for very long compared to the lifelines

Re: 48 Volt battery pack financial wiring

Their battery packs are (consequently they are) in far better form than my own were. If storage acts me correct, i believe some of my personal batteries comprise checking out as little as 11.5V as I took all of them out of the box. They seated for just two MANY YEARS before I bought them. More battery packs are higher, however they are all over the place. These people were all low!

I thought I became obtaining much spending around 1/3 rate (obtaining 3 for the cost of 1)!. In actuality I was having to pay plenty for scrap lead ! UGH! Really amazing at how well they’ve are available around all things deciding on, however they are not the things they should-be. 1 day we decide to do it right. For now, these are generally enough for what I need.

As time goes by, I’d like to bring a few chain associated with the 6V Lifeline GPL-6CT (oversized tennis cart dimensions) which are ranked at 300A/H each. This time around, i will make sure these are generally factory fresh as well as from the same good deal. And that I’m planning to treat them as if they are produced from SILVER!

Cheers and you will reveal David the design.

Re: 48 Volt electric battery bank wiring

I’m not a fan of cross trapping electric batteries of various chain. I prefer to keep each sequence as separate.

Crosstrapping makes it difficult to discover a battery going poor. In addition, it have a greater potential for taking right out most great electric batteries because the worst power starts elevating the charge current on different batteries. You’ll be able to juggle electric batteries around occasionally to complement right up collection connected current per electric battery and existing for each and every sequence.

We have ten strings of four series 12v electric batteries (forty batteries).

I have 100 amp shunts on adverse contribute on every with the chain and monitor each battery packs voltage frequently. I have one common 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 each associated with five carts. Carts take casters therefore it is simple to take the Anderson connector and move just one cart out for provider.

Each cart is 27″ very long, 24″ higher, and 15″ deep thus doesn’t fill up excess space from wall surface. Welded all five collectively, generally from salvaged bedframe perspective iron.

Been operating this config for around fifteen years. The 5th cart at far correct got a later add-on rather than matched up for line size but There isn’t a lot current difference because of low current per string using 2/0 interconnects.
