I’ve 16 of the identical electric batteries, and I additionally skilled several of just what you will be describing with unequal battery-charging.

With my own, i understand that they are sulfated to different grade, so that provides caused some of the imbalanced battery charging voltages. I bought my personal Lifelines at a reduced rates as “NEW”, nonetheless had seated for a long time and were deeply released before We previously have them. In addition wound up position my personal fee voltages within lowest conclusion of Lifeline’s information, so as that I would personallyn’t overcharge many electric batteries.

Functions okay for a crisis backup power supply system this is certainly rarely neeed, however they are definitely not the things I’d desire to be determined by for every day off grid dwelling. Some day, i really hope attain a brand new group of battery packs acquire to best beginning (and capture very good proper care of all of them).

Re: 48 Volt battery financial wiring

Here’s Edward’s “keyturbocars” thread where he performed a bunch of research and evaluating a setup to recover Lifeline AGM battery packs:

If the battery packs in series (and match) tend to be terribly mismatched (i.e., close battery pack in collection with sulphated battery) could cause the unbalanced charging in which one battery pack try charging you at “low voltage” plus the additional at “high voltage”.

Charging/recovering batteries separately might help. Additionally matching batteries by capability (“high” ability in a single string, “low” capability in a moment collection sequence) can help too.

Re: 48 Volt electric battery bank wiring

I agree with Statement. Managing each battery individually is a great idea. I did they also it did let my scenario. Having said that, my battery packs comprise yet gone to start out with that the scenario remains perhaps not great. Things are better however.

If for example the power supply lender is newer as well as in better state subsequently mine, then trying to equalize each electric battery separately in accordance with Lifeline’s procedure might provide great outcomes.

Re: 48 Volt electric battery bank wiring

Last I inspected the resting current they were within .01 to .10 of every more. (really my batteries never “rest”). Just inspected (7:25 PM).. Neg area match battery packs at 12.75v, .07 to .10 raised above other battery packs with about a 150w to 200w burden.

I got myself the very first two electric batteries March ’10 as well as the latest sequence of four in Oct ’10. (in addition, two of the chain have released batteries (12.5 – 12.7). I wasn’t pleased to bring compensated that kinda revenue for brand new electric batteries and must invest several days charging all of them before i really could make use of them).

Overall, I’m ecstatic with these little Lifeline battery packs..

I’ve another tiny 4-battery-12v-system of Costco wet-cell electric batteries. Little greater overall amp hrs compared to Lifelines but of course, they simply can’t take a lot of a load for a long time compared to the lifelines

Re: 48 Volt power lender wiring

Your own electric batteries were (consequently they are) in much better form than mine happened to be. If memories serves myself right, i do believe a few of my battery packs comprise reading only 11.5V while I got all of them from the box. They seated for just two AGE before i got myself them. Additional battery packs were larger, nonetheless they were all over the place. These were all really low!

I imagined I happened to be getting a great deal spending around 1/3 price (acquiring 3 for price of 1)!. The truth is I happened to be having to pay loads for scrap contribute! UGH! It really is incredible at how well they usually have arrive around things considering, but they are not at all whatever they need. Eventually I propose to do it right. For now, they’ve been sufficient for just what I wanted.

Down the road, I’d like to bring one or two chain for the 6V Lifeline GPL-6CT (large golf cart dimensions) which are rated at 300A/H each. Now, i will make sure that these are typically factory new and all sorts of through the exact same good deal. And that I’m attending address all of them as if they are made from SILVER!

Thanks and you will showcase David the drawing.

Re: 48 Volt power supply bank wiring

I am not saying keen on mix trapping battery packs of different strings. I prefer maintain each string as standalone.

Crosstrapping makes it harder to detect an electric battery heading worst. It also provides a greater potential for taking out extra close battery packs due to the fact bad battery pack starts increasing the fee voltage on various other batteries. You can easily juggle electric batteries around occasionally to fit upwards collection connected voltage per battery http://besthookupwebsites.net/nl/the-inner-circle-overzicht pack and current for each and every sequence.

I have ten chain of four series 12v electric batteries (forty batteries).

I have 100 amp shunts on unfavorable contribute on each for the chain and monitor each electric batteries voltage regularly. We have one common 500 amp shunt for a trimetric monitor.

I’ve two synchronous strings per cart (about 550 lbs per cart) with 350 amp Anderson connector for each and every with the five carts. Carts are on casters it is therefore an easy task to draw the Anderson connector and move just one cart for provider.

Each cart is actually 27″ longer, 24″ higher, and 15″ deep therefore doesn’t use up extreme space from wall structure. Welded all five along, generally from salvaged bedframe angle iron.

Been operating this config for fifteen years. The fifth cart at much appropriate got a later add on and not paired for cable duration but I don’t have much voltage variance due to low-current per sequence making use of 2/0 interconnects.
