Hi, thanks again for all the information you have provided, I have learned a lot. I did open the battery once more and tried to check...

Refer to my long-winded explanation of the possibility of recovering low-volt cells on my previous build's post. Please be extra...

It's more likely to work with a newer battery (having quality name brand cells) with fewer cycles that was accidentally over-discharged...

Will the lower resistance of a new 4p group of 25r cells (fully charged) be discharged to 50% SOC before any of the other nine 4p groups...

You are correct (13p). What can be confusing to some is the 14 readouts in those charts. Each of the 14 readouts is the average combined...

You have a 10s4p battery. The parallel group of 4 cells having only a voltage of 2.5v needs to be replaced. Each of the 4 cells in each...

In your first post you said you have a 14s13p battery ... yet both of your above graphs indicate there are 14 parallel groups. A 5%...

At 53.4V approximate average of 3.814V per parallel group except Group 1 at say 3.800 (14mV delta variance). Let it sit for 2-3 days to...

More than 100mV (general rule of thumb) is when there is a variance among the 14 groups of at least 100mV or greater when the battery is...

Not enough to promote a great concern. Do not worry. Delta V across the cell banks is not that bad. When the delta cell to cell...

N.E.S.E. is an 18650, 21700/20700 and 26650 size cell modular system made for simple battery building and assembly which does not...

Agree ... it's enuf of a labor intensive reverse challenge (and expense) just converting one of the above chassis ... than starting from...

Well, they are pink and say 18650, but do they say Samsung 35e ? That wrapper burn through to can metal edge might be of concern if it...

More so with 30q than other high energy dense 18650 cells. 30Q cells for whatever reason were more prone to high self-discharge being...
