FAQ
Can I use this battery as a starter battery?
No - this battery is not designed for use as a starter battery. It is a deep cycle battery intended for sustained energy delivery in off-grid, RV, and auxiliary power applications. Using it as a starter battery is not recommended and may void the warranty.
How many of these batteries can I connect together?
You can wire up to four EX1 batteries in series or parallel to scale your power bank. Always follow the included manual closely when wiring multiple batteries to ensure proper safety and avoid damage to your system.
What does the SmartTalk Bluetooth feature let me do?
The SmartTalk app connects to your battery via Bluetooth and allows you to monitor real-time data including state of charge, voltage, and overall battery health - all from your smartphone. It's an easy way to keep an eye on your power without needing a separate battery monitor display.
Can I mix this battery with my existing lead-acid or other lithium batteries?
No - do not mix batteries of different ages, sizes, or chemistries in the same battery bank. Mixing battery types can cause imbalanced charging, reduced performance, and potential safety hazards. Also, do not mix with lead-acid batteries when recycling.
What is the return policy on this battery?
Due to shipping regulations regarding hazardous materials, lithium batteries cannot be returned or refunded after purchase. Please verify compatibility and fitment before ordering. The battery is covered by a 12-year manufacturer warranty for defects.
Does this battery require any maintenance?
