📐 460AH FOR SPACE-CONSCIOUS INSTALLATIONS

The Next Generation Ultra Slim range is designed to maximise battery capacity while minimising the depth required for installation.

Suitable applications can include:

• Along canopy walls
• Under false floors
• Inside custom 4WD storage systems
• Caravans & camper trailers
• Motorhomes & RVs
• Mobile trade setups
• Remote-work & high-capacity off-grid systems

The battery body measures approximately 610mm L × 405mm H × 116mm W.

The stated overall dimensions are 645mm L × 475mm H × 119mm W.

---

🔩 IMPORTANT MOUNTING RAIL INFORMATION

When installing the Next Generation Ultra Slim battery along the base of a canopy or similar horizontal surface, Custom Lithium recommends not using the bottom mounting rail.

This allows the battery weight to be supported directly by the vehicle or canopy floor instead of placing unnecessary load on the lower mounting system.

⚠️ For base-mounted canopy installations, support the battery directly on the floor as recommended by Custom Lithium. This reduces stress on the mounting system and is intended to improve long-term stability.

⚡ HIGH-CURRENT PERFORMANCE

The stated 380A continuous discharge capability provides substantial current availability for high-demand auxiliary electrical systems.

This makes the 460Ah model suitable for appropriately engineered high-power inverter installations, but inverter selection must still account for actual DC current demand, start-up surge, cable sizing, fuse protection, battery state of charge, connection quality and BMS limits.

---

🔌 HIGH-CAPACITY CHARGING

The supplied specifications recommend a charge current of up to 230A.

• Recommended Charge Current: 230A
• Bulk / Charge Voltage: 14.2–14.6V
• Absorption / Float Voltage: 13.4–13.6V

Lower-output compatible charging systems can also be used, although recharge time will increase accordingly.

For a battery of this capacity, the complete charging strategy should consider available alternator charging, solar capacity and 240V mains charging rather than relying on a single charging source.

❓ QUICK FAQ

How thick is the Next Generation Ultra Slim 460Ah battery?

The battery body is approximately 116mm thick, with a stated overall installation thickness of approximately 119mm.

Where can the 460Ah Ultra Slim battery be installed?

It is designed for space-conscious installations such as canopy walls, beneath false floors, custom 4WD storage areas, caravans, motorhomes and other high-capacity off-grid applications.

Should I use the bottom mounting rail when mounting it on a canopy floor?

No. Custom Lithium recommends that when the battery is installed along the base of a canopy or similar surface, the bottom mounting rail should not be used. The battery should instead be supported directly by the floor.

Can this battery run a large inverter?

It can be used as part of an appropriately engineered high-power inverter system. The supplied continuous discharge rating is 380A, but suitable inverter size depends on actual DC current demand, surge requirements, cable sizing, fusing and BMS limits.

What charging profile should I use?

The supplied specifications call for a 14.2–14.6V charge voltage and 13.4–13.6V absorption/float voltage.

What charge current is recommended?

The supplied recommended charge current is 230A. Lower-output compatible charging systems can also be used, but will increase recharge time.
