I am right now doing the math in my head as to if I want to go this direction. If I get your setup, I would need a spot welder, and nickle sheets, and wire to make it happen. I guesstimate you have 6 KWH of battery there, I am finding EV batteries on Battery Hook up for $100 -$120 per...
I have the same cells, I just bought a 36v inverter and hooked all 3 of min in parallel. I have a thread going about my adventure here ->
I soldered them at first then after those...
Thanks for this thread, I have been doing similar with my Raspberry PI using a program using domoticz.
Here is a video I made of my voltage monitor I created with an ESP 8266 combined with espeasy.
Hyundai Ioniq Electric: 28 kWh
I have found a source for this battery, and I wondered if anyone here knows anything about it. I am strongly considering getting it and breaking it down to cells or simply leaving the pack be exactly as it is and getting a charge controller to match...
Ok, back on this thread again. :-) I have fixed set of 2 low batteries. the solution was to put a 12 V car charger at 3 amp to the cells directly. I did this at 2 hour intervals checking and verifying that the power came up on them, after 14 hours of charging in this manner the cells...
I am thinking of getting a nissan leaf ( car) and just charging the thing with the standard charger at 120 V, but I am looking to see if there are inverters out there that will just plug in. Lots to consider when doing this.
Yep I have been looking for a power supply that will match 4 v, 72 amps..... I do want to push both of the banks up, but not sure how to get it there.
I have considered putting a load on the other cells to get the resistance to match so the other cells will charge.
It does make sense that the bms would balance on the top end. I have been trying to figure out how in the world to charge just these 2 cells banks at such a high capacity.
But as I thought about it, I starting thinking these two cell banks are in series, if I charge...
I have not, nor do I wish to drop the pack down to the min level, I have destroyed one pack by taking it down that low, not wanting to risk that. I have been using this just by powering the 24 V terminals on the battery. So now I need either to find a BMS for this, or to hack the one...
Thanks for your reply.
I have been looking into this hack of the battery ->
But the requirements of my BMS would be able to deal with the flux charging of solar.
Yes you are wise in saying 4.1 as the top of the batteries should go, that...
I have been running a Tesla Model S module with solar with my Outback controllers for over 5 months. I love lithium!!!!!!
Now I have seen the need to get a BMS for this setup, and adding more logic as I have found that the batteries will DIE if they are charged at 32 degrees!
