Rich Solar ALPHA 1 PRO 12V 100Ah LiFePO4, hardly used. Evansville, Indiana. Local collection only — see below. WHY SELLING: Moved to a larger system.

Battery only — no box, no accessories. NEW PRICE: $599.99 from Rich Solar. ASKING $349. I know the commodity 100Ah market is around $200-300. What you are paying the difference for here is the self-heating, the Bluetooth BMS and the UL1973 listing. If none of those matter to your build, buy a cheap one — I would rather say so than waste your time. COLLECTION ONLY. I do not have the original certified packaging, so I cannot meet the UN-spec packaging requirement for a Class 9 shipment. I am not going to improvise that with a lithium battery. Happy to show it live on the app before you commit, and to answer anything.
