The SJRV VanDIY Lithium Battery Series

Power Your Adventures: The VanDIY Lithium Battery Series

Whether you are upgrading a caravan, converting a van, or building an off-grid system, the battery is the heart of your setup. VanDIY’s 100Ah, 200Ah, and 300Ah lithium batteries are built for tough conditions, reliable performance, and long service life.

Why LiFePO4 Over Lead-Acid or AGM

  • Lighter weight for the same usable capacity
  • Safe to discharge deeply without damage
  • Thousands of cycles with minimal capacity loss
  • Minimal maintenance compared to traditional batteries
  • Stable voltage output under load for inverters and fridges
  • Safe chemistry with strong thermal stability
All VanDIY batteries use A-grade cells and include a full Battery Management System for protection. Each model is housed in a metal case for strength and thermal security. See details at VanDIY.
