I'm curious to know if there's a market for used batteries. My roommate picked up four 100Ah 12V Enerdrive LiPo4 slim batteries from work at a low price. The catch is, my system operates at 48V, and according to the manual, these batteries can't be put in series due to the Battery Management System (BMS). Returning them isn't an option since we've passed the 30-day policy. Other than platforms like Facebook Marketplace or Craigslist, are there any good places to sell these batteries?

I just want to clarify, you mean you're trying to connect those four 12V batteries in series to achieve 48V, right? Selling them on marketplace is a viable option, but keep in mind that most buyers might want to have them tested before purchasing.

Yes, I meant to say series configuration instead of parallel, thanks for catching that!
