Battery – 135Ah Lithium Battery with Bluetooth & Inbuilt Heater

Lithium battery technology is becoming popular with leisure vehicle owners – providing lower maintenance requirements and the ability to use the full battery capacity without damage. OPUS offers an optional 135ah lithium battery to extend your off-grid capacity for the on-board 12v system.

This battery offers an increased 25ah capacity than the standard lead acid liquid battery (110ah), as an example this means you can charge your phone 50 more times*. It is also lighter and has a better lifespan, in turn making it better for the environment.

The battery comes with its own inbuilt heater to keep the battery at optimal performance during use.

Some key benefits compared to a lead acid battery:

🔋 Performance & Efficiency

• Higher energy density: More power in a smaller, lighter package.
• Faster charging: Typically 2–3 hours vs. 8–12 hours for lead-acid (depending on a charger)**
• Consistent voltage output: Delivers steady power throughout discharge.
• Bluetooth App: Can monitor battery status on your phone. The following links will take you to your relevant app store:
  • Android App – Bluetooth Li
  • Apple App Store – Bluetooth Li

🔄 Longevity & Durability

• Longer cycle life: 3000–6000 cycles vs. 300–500 for lead-acid.
• Deep discharge tolerance: Can safely discharge up to 80–100% without damage.
• Low self-discharge rate: Holds charge longer when not in use.

🌡️ Safety & Reliability

• Thermal stability: Less risk of overheating or thermal runaway.
• Built-in BMS (Battery Management System): Protects against overcharge, over-discharge, and short circuits.
• Operates in wider temperature ranges: Often from -20°C to +55°C.

🌍 Environmental Impact

• Lower carbon footprint: Fewer replacements mean less waste over time.
• Less frequent charging when in storage: Lower costs and lower power from the electricity grid needed to maintain – Less Pollution.

💰 Cost Efficiency

• Lower total cost of ownership: Higher upfront cost, but fewer replacements and better performance make it more economical long-term.
• Minimal maintenance: No watering or equalization required.
• Less charging: When not in use the battery needs to be maintained a lot less.
