That may be true but it is also being sold by DLJBERMPW too for $439 and $404. I wrote to them and they said it’s the same battery but the one link is participating in a short Amazon promotion. They also said they were prismatic not pouch. Based on their reply I went ahead and bought one.

Thanks, I see the ad. Those are the minis. I wonder if they're pouch or prismatic inside.

Unfortunately they sell both. I'll try and ask them what the difference is.

In thanks for the info on the Djl…. Which of these two did you get? (I don’t know why there is a price difference - one tear down showed pouch cells)

Set your boost and equalize voltage to 13.8V with a 2 hour equalize time. That's likely lower than your BMS turnoff voltage for your out of balance cells and give it time to equalize over a period of days. You really don't gain much more capacity going to a higher charge voltage. I test a lot...

Seeing as they're both in parallel, what could you possibly do to bring them up equally that just running them wouldn't do? What's your peak charging amps? Imbalanced batteries in series are a problem but I don't think parallel is except during initial connect so you don't trip or needlessly...

I keep waiting for batteries to get cheaper, and they do seem to have dropped a bit this past week. I need to add more storage so I can put more into my EV at night when I get home and to lower the peak current I'm pushing back into the batteries when charging. Of these 24V 100AH batteries...

That's how these things work - it's a 4-wire setup, each half of the jaw is insulated from the other. It applies a load on one half of the jaw and measures the voltage on the other. The voltmeter resolution is very good and based on the drop, gives you the batteries' internal resistance value.

There's a notable size difference between the EcoWorthy and DJLBERMPW. Are the EcoWorthy's pouch cells?

Is this with no load on the battery when you're charging? Or are you pulling a load while also charging?

Are these pouch batteries? Do you have any of these? I'm looking to add another 200AH to my 24V system and these are priced right.

I remember those! I have one I bought in the 90's around here somewhere

All the power tool chargers I've had have switching power supply type topologies and have horrible power factor. So I'm guessing that though it's 550W of draw, VA rating is very different and it is confusing the protection circuitry in the Giandel.

Eco-Worthy on Ebay has a 20% Springtime coupon. I really want to get their 280AH pack, but the largest is 12V 280AH, they don't offer a 24V 280AH. I could get 3 of the 24V 100AH packs but it isn't as cheap as the 280AH. Still $391 per 24V 100AH battery is pretty good.

Eco-Worthy on Ebay is offering 20% off, 12V 280AH for $432
