ESV2-300 is Strongna’s 2V / 300Ah valve-regulated lead-acid cell in the ESV2 stationary range. It’s built for storage banks that need high capacity per cell, then reach system voltage by connecting cells in series.
Typical homes for this cell are solar backup strings, UPS banks, and industrial standby arrays: one upright 2V block that sits in a rack and works as part of a larger pack.

When to Choose This Model
- Pick this model when you want a 2V single cell for a high-Ah string — not a ready-to-use 12V block. If your design builds system voltage by series connection, start from the ESV2 capacity that matches your bank.
- If you mainly need a compact 12V module for smaller backup, look at Strongna’s 12V storage range instead — ESV2 is for bank-style installs where cells are combined.
