Thanks as always. And amazing job I gave up testing the cells to find the disconnected one.i get help now. My wife helps on one side I tap her leg to move on. As saying next got old aswell
Thank you! Yeah. I thought about just letting it be after testing. But I just couldn’t. I won’t test it again if I only find one or 2 mistakes. But 3 or more and I do. I got too cocky with packs 1-5 because Packs 6-10 I’m finding more errors. Pack 6 had 5. Lol. My girlfriend just thinks we’re all mad scientist. Thats amazing that your wife helps like that. Sounds like you landed one of the good ones. 🙂
you should update your icharger firmware to 2.1.0 it can fix some problems, and for proper capacity test you need to set the charger to 4.2v and 2.8v for disharge
I just updated them all. Took me a sec to figure out how but I got it done. Thank you for the advice. 4.2v-3.0v is ok for me so far. 2.8v is just a little to low. Especially if I have to test them more than once. When Done. They’ll never get below 3.3v-3.4v is why
Kind of. Blue cells tested around 2600mah-2800mah. The purple were 2700mah-2900mah and the green were 2900mah-3200mah. Separated all of them by 100mah and then divided them all up so they be around the same (theoretically) for each of the 30 packs. But it actually worked out great. I’m on pack 23 of 30 right now and the range is 630ah-640ah for each pack. Took me days to do it. There’s 7,200 total cells.
@@myteslapowerwall7314 you must have very good supply of cell, where i m its very hard to get my hands on to any laptop batteries due to recycling law, but what i can get, have range from 1600mah to 2600mah, i think my packs aren't going to be as dense as yours (energy wise) i was thinking to do 80cell pack but after watching your videos i m going to do 200cell pack, i m aiming for 25 to 30kw power wall but its long way to go. Keep your videos coming they are very motivational and informative
Thank you so much. More videos are on the way. Got sick with a cold/flu and then 2 weeks later got covid. Tired of being sick, but I’ve been working on the Timelapse video of all 30 packs being tested.
What happens if your middle battery pack got full charged and there is still some amps left in your green packs? How and where icharger dump the energy? I think icharger only monitor one pack i.e gree cell pack so you have to keep eye on your blue pack (middle pack) ? Can you share bit how its put together, i m on cell harvesting and testing phase
Yeah I do have to monitor the big blue pack. Usually I’m fine if one pack is discharging at 30a and the other icharger is charging at 30a. But it does drain more than it puts back in at times. So I have to plug in the ac-dc charger so it doesn’t die. If I forget to unplug the ac-dc power and it charges to full. I’ll plug the blue pack into a dc-ac inverter and I’ll power my tv, soldering iron, charge a different battery pack that may be low. Then I can start regen charging again. It’s only happened once, but that’s a good question. You’ll notice in my next video coming up that one time lapse took 32 hours (normally 21 hours). That’s because I left the ac adapter plugged in and the blue pack charged to 100% when I was only 1/3 of the way done with the regen discharge test. It went from 30a to like .02a. It was still running the test, but it did jump back to 30a once I started discharging the blue pack again.

great build .. Should have used lugs instead of clamps to get proper connection ...
Thank you. And That’s fair. Haha

Why not use the regenerative discharge feature with one iCharger? Trying to wrap my head around the use of two….
You packs are very close to each other in capacity, all these cell rated same capacity? Or you mix n match cell with total capacity to same?
Kind of. Blue cells tested around 2600mah-2800mah. The purple were 2700mah-2900mah and the green were 2900mah-3200mah.
