Trying again to sell this. I got in over my head by buying a used Valence U27 off ebay. I don’t think it’s worth it for me to tear it down and add a BMS or buy the Valence one, and for a used-once-in-a-while cobbled together solar generator, it just doesn’t seem worth my time or money to pursue. $450+ shipping, or if you are local to Binghamton NY we can arrange pickup.
