This ended up taking quite a while, but more so because I was busy doing other things much of the time. The verdict: The pack is back in the...
Pack tested. (y) [IMG] So I'm going to pull out 1, 5, and 9. Then I went and paired the modules better, at least in a computer, to visualize...
It could be that my best modules in the pack are only 3000mAh. Too soon to know. But after a pack test with DrPrius I can calculate a multiplier...
Ok. I've tested a little over half of the pack so far. It's looking very interesting! Just a reminder for any future readers, I still don't know...
So if we look at the amount of time this takes for those two modules, between 255 and 310 seconds, that appears to line up pretty close to the...
Thank you, haha. So folks, two things have happened: 1) I heard back from Jack, and he didn't tell me a mAh value for 80% to 40% SoC discharge,...
Hehe. My situation is that I bought the car for 1/2 Kelley Blue Book and 1/6th of MSRP. 8 years old and with 139k miles plus a dead pack at the...
[ATTACH] This is from a new cylindrical pack. DrPrius went past the 15 minute discharge timer by another 5 minutes. Complicating the measurement...
I'm an extremely persistent startup founder with a tech generalist skillset. If I don't know how to do something, I learn how to do it. I take...
Ok I tried again but asked the AI to factor in the operating range of voltages. This feels more directionally correct. The usable capacity...
I'll need to think about why DrPrius doesn't discharge 2.6Ah but rather 1.625Ah for the life expectancy test. I'll also look around for a DrPrius...
I emailed Jack, but I also asked ChatGPT (AI) to calculate usable capacity with the knowledge that the DrPrius discharge test ideally pulls 6.5A...
From what I understand, it pulse charges at high amps (up to more than 60A!, but mostly 30A) (hit the gas, wait, hit the gas, wait, etc) until the...
Wouldn't DrPrius only show the capacity of the weakest block?
Noted. I think what I'm going to try first is compare "usable" capacity of the pack modules going from 8.4V to 7.1V. (after a prolong topping...
Are you inferring that there is no benefit to having blocks with the same capacity in a pack? I was under the impression that this could extend...
Half the pack is ebay modules at this point. I have no insight into the capacity of any of the modules as I bought the car used with a dead pack....
Good catch RE: outliers. I do have bad modules and weak modules. To be clear, I'm only pack charging and module discharging, as of now. If the...
If I'm reading this correctly, S Keith said 13A discharge is doable.
Right. This is precisely why I'm switching over to prolong for the charging. The cooling is already there in a sealed pack (and prolong utilizes...
