Smarter Technology for Your Rig

This Ionic lithium starter battery is packed with advanced features that save time, prevent service calls, and protect your investment:

Emergency Start Feature

Never worry about a dead battery again. The integrated Emergency Start function allows you to use a reserved energy buffer (25% capacity) to jump-start your rig simply by pressing a button or activating it via the Ionic App on your smartphone. This prevents frustrating and costly downtime.

Advanced BMS and Bluetooth Monitoring

The advanced internal Battery Management System (BMS) provides essential safety protocols, including cell balancing and protection against overvoltage, short-circuit, and low voltage. Additionally, Bluetooth monitoring allows you to track the battery's real-time health, voltage, and state-of-charge from your cab.

  • Anti-Theft Power-Off: Use the App to remotely disable the battery's output when your equipment is parked.
  • Drop-in Fit: Designed as a direct, drop-in replacement for BCI Group 31 lead-acid battery setups, utilizing the same post layout for hassle-free installation.

Long-Term Value: Lithium vs. Lead-Acid

While the initial purchase price of this lithium battery for diesel trucks is higher, its superior performance and lifespan translate to substantial long-term savings:

  • Extended Life: Outlasts traditional batteries by 2–4 times, minimizing replacement costs and labor.
  • Faster Turnaround: Charges up to five times faster, significantly reducing vehicle and equipment downtime.
  • Zero Maintenance: No acid, no leaks, and no maintenance required over its entire service life.
