They are still taking charge and will do so until they are all at a matching voltage more or less. It's never perfect. The reason they are taking such low amperage is the internal resistance of the cells within the packs. One thing you can do is to increase the absorb time when charging and...

REALLY ? That's news to me, and we have as much BDDY as TSLA and of course I keep an eagle eye on those shares & companies. Sorry to say but BYD has a good safety record with batteries and their Raod Safety Testing surpasses even European standards.

There is a significant different in the eyes of Duties Import/Exports. The "Made In ??? or the Assembled In ??? is handled quite differently. The finer points are only known to those that deal with that directly. What effects to Canadians... If coming here directly by boat/plane or if...

It takes time. as the packs reach the set point voltage and the cells level up the Voltage will remain same but the Current will drop. When you have multiple packs in lay like this, they will slowly flip on/off (so it will appear) as it continues but they start taking charge as all packs...

What exactly will happen & when it will be implemented at this point is just SPECULATION right now. It will all be released on May 21st (next Tuesday). Given the timing of the Announcement of this and when an "Official" release will be, is curious. Shock up front and less in reality ? see...

One side effect will be the "components" segment which is chips, processors and such. Products that are "Assembled In *******" use parts from Global Sources including China... Guess what, most electronics have some parts from China within. Full Details will become available May 21st, then a...

The latest information on Credible News Sites is that on May 21, Tuesday, the official details will be released. YES, Battery Cells, Solar Tech (Panels & related hardware) will all get Massive Duty increases, up to 100% on several items. This WILL have severe effects on US Companies using...

Cell deviations always appear after 3.400Vpc and with a deviation of 0.030 @ 3.500 is still in chuckle worthy territory as it's insignificant.... now 0.100 out is cause for an eyebrow raise & closer look. The main reason a lot of folks have issues with battery packs & balancing is 95% of the...

It certainly seems to be the end of Cheap Cells & Tech from China for the US. What & How others will react & the fallout effect we DIY types will likely be unpleasant. The other shoe to drop, is what will China do to counter it... and what will that cost us poor shmucks too ? When & How bad...

I went from FLA to LFP - yup lots to unlearn, shit loads more to learn too. Ohhh the "Subtleties" are enough to make one cuckoo during the relearn process.

Have a browse @ Midnite, their E-Panels do Magnum, SMA, Schneider, Victron ... https://www.midnitesolar.com/products.php?menuItem=products&productCat_ID=4

The A-Typical setup inside a "Rack" type case, is that when installed, the cell terminals & vents are on top and under limited compression. We have seen circumstances where cells on their sides have leaked and caused issues resulting in failures, a few resulting in fires. The electrolytes are...

You can easily put Float to 55.0V and get the full use of the working range charged & topped. I found the "Sweet Spot" for the active balancing to start @ 3.4 so it can do it's work while in float. BUt by the time my packs reach float, there isn't that much difference usually.

Nice & Tidy but with a gotcha... The cells inside those rack mountable are now sideways and that is NOT good. I seriously suggest you get them OFF the ground and on a shelf, even stack them one on top the other (use small rubber gripper feet or pad to keep them from sliding) and you'll be...

Once the entire bank get's "settled" and working properly after a few cycles with a proper profile, they should all level up & balance out. That being said, it will NEVER be "perfect" there will always be a wee bit of deviation between packs which is normal & expected. Now that deviation...
