Gonna sell my Chevy Volt setup

[simicrintz]

Posting here first since (will post in For Sale section also) there is some back history in this forum (and huge thanks to all who provided help and input for me to be able to pul this off). Being in the backyard of Eco Battery and able to talk with them, I just had to have one of their setups! I offered my Volt setup to my son, but after seeing my Eco Battery system he has decided that he wants to go in that direction as well!

The batteries were purchased as new units in 2020 and have less than 2 hours on them. They have the correct BMS on each of them, and I am including the shunt (it is missing a bolt as you can see in the pic), the AH meter that I used (reads AH, Hours, Amps and Volts), and the custom built for this application Schauer charger. I have close to $2,500 in the above, would like to see $1,500 for everything plus actual freight to ship.

I'll post pics, but I think there is a 5 limit per post so it may take a few. Please let me know if you have any questions; thanks for looking

The bummer with these as they are only 12S. My Leaf module pack is 14S which I would much prefer.

Yeah, but yours are LiFePo and mine are Cobalt

Nope. Mine are 4.2V per cell! (Leaf is not LiFe)

I hate arguing with people that are smarter than me!!

I thought I had you with this: LifeP04 cells are 3.2v and Cobalt is 3.7v. Cobalt holds much more energy.

Thank you for teaching me something

Most drop in's if not all are LiFePO4 chemistry. It's safer but lower voltage. Most drop in batteries are 16 cells. I like the Leaf cells I have but they are getting impossible to get. The newer leaf batteries are not made of 48 separate modules like the originals so you can't easily harvest them for golf cart use. They do have some 7 cell modules in their pack - and I got two of those for my second cart. But most of the modules are not useful for us so it's not practical to harvest these packs for our use. I have 6 years on my first Leaf pack still going strong and as good as when I built it. I don't know what I will do if I need another battery - I won't do a drop-in with what is available today. Some are ok but I want to know much more about the actual cells I'm using and I would rather build my own pack and BMS.
Volt batteries are good cells - just not as convenient as the old Leaf modules to get a 14 cell pack. A 12 cell pack will work but I would want the extra voltage. Not sure how available they are anymore either.
