I have 33 individual 230Ah li-ion battery cells. This is enough to make two (2) 48VDC battery packs (32 plus one spare).
I have attached the manufacturer's spec. sheet, these are considered 1st quality cells and were only used in a study where I calculated the battery round trip efficiency (they are quite good, results were above 96% depending on C-rate). They have been cycled a total of 15 times (round trip), which was all I needed for my test results, plus some individual cell charging/discharging when I was balancing the packs. These are basically in like-new condition. I will include the battery bussbars and bolts so you can connect them up in whatever parallel/series configuration you wish for your application.
When I was testing these as two (2) 48 VDC packs in parallel I was getting 20 kWh out of the system (or a little more than that) each run.
Asking only $1600 for all 33. Local pickup preferred (bay area CA)
