Lithium and Solar Battery Discounts for Black Friday 2026

This page collects every battery currently marked down for Black Friday and Cyber Monday: 48V server rack and wall-mount LiFePO4 modules for home systems, 12V and 24V packs for RVs, vans and boats, and expansion batteries that add capacity to a power station you already own. The list updates on its own as prices drop, so what you see here is what is discounted right now.

How to pick the right battery deal

  • Match the voltage first. A 48V inverter needs 51.2V modules; a 12V RV system needs a 12V pack. A big discount on the wrong voltage is not a deal.
  • Compare price per kWh, not per Ah. Divide the price by the stored energy to see which lithium battery deal actually gives you more storage.
  • Check cycle life and warranty. Sale batteries keep their full ratings - 6,000+ cycles and 10-year warranties are common on the home modules.
  • Indoor, outdoor or mobile. Server rack modules live indoors; IP65-67 all-weather units mount outside; sealed packs suit boats and trailers.
