Enerdel High Current 48V 32Ah 1.4kWh Used Battery Module 95% SoH $150 Free Shipping to Lower 48 States

We have these Enerdel modules that can handle some serious current.
Each module has terminals under two side covers that can be unscrewed. It is possible to completely remove the ribbon cable and install your own voltage harness with ring terminals to make wiring a BMS easier. Battery is built in a 12s2p configuration. You can also break the module down and rearrange it to whatever voltage you would prefer with little modification. These modules are used, they were removed from hybrid busses. Battery terminals are on top and very easy to connect to, fins are on the opposite side of the terminals and are for heat dissipation, if the modules get warm, you can blow air over them for accelerated cooling.
We have cycle tested several modules and have found they come back as 30-31Ah, nearly full health.

How balanced are the modules you've tested so far? Are all the cells exactly the same voltage at full? And still the same as each other when empty?

Any idea of amount of voltage sag under load?

Just trying to compare to my ancient EIG packs (which are nearly a decade and a half old, and still balanced without any BMS), but which are sagging more and more and losing enough capacity that it's about time to replace them.

Ive attached two pictures from one of the tests. The graph has sudden drops like that because the data from the RLEC sometimes drops out, we have found that is a common thing on the Enerdel BMS. The graph gives you a visual representation of how far apart the cells are throughout the test.
The other picture shows the voltages of the cells as the test started and as the test ended. Both data points were recorded under a 10A load.
To make it easier for you, I've pulled the max and min values from the screenshot and rounded up a little.
Start of test Max: 4.111V Min: 4.102V Delta: 0.009V
End of test Max: 2.607V Min 2.498V Delta: 0.109V
