A balanced capacity for mobile and off-grid use

The VONBLAY 12V20A sits in the middle of the 12.8V LiFePO4 range at 20Ah / 256Wh. It is specified for solar and wind energy storage, marine electronics, mobility equipment, RV systems and backup power at remote sites – applications where more usable capacity matters but a compact, portable pack is still preferred.

The model stores twice the energy of the 10Ah pack on the same 12.8V platform, with the same built-in Battery Management System, low self-discharge and 2000+ cycle rating. The sealed case contains no lead or free acid, and its lower weight simplifies handling and mounting.

Key features

  • Built-in BMS – protects against overcharge, over-discharge, over-current and short circuit.
  • 2000+ charge cycles – a long service life from lithium iron phosphate chemistry.
  • Low self-discharge – holds its charge through long periods of storage.
  • Sealed, lightweight case – easy to carry and mount.
  • No lead, no acid – a sealed LiFePO4 pack.
  • 12-month warranty – the same coverage stated for the whole 12.8V series.
