📐 310AH FOR SPACE-RESTRICTED INSTALLATIONS

The Next Generation Ultra Slim range is designed to make use of narrow and otherwise difficult-to-use installation spaces while retaining substantial battery capacity.

Suitable applications can include:

• Along canopy walls
• Behind suitable vehicle seats
• Under false floors
• Inside custom 4WD storage systems
• Caravans & camper trailers
• Mobile trade setups
• Remote-work & off-grid systems

The battery body measures approximately 610mm L × 405mm H × 85mm 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 fully supported 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 installation stability.

⚡ HIGH-CURRENT PERFORMANCE

The stated 330A continuous discharge capability provides substantial current availability for demanding auxiliary electrical systems.

This makes the battery suitable for appropriately engineered high-power inverter installations and other high-current 12V loads, but inverter selection must still account for DC current demand, surge requirements, cable sizing, fusing, connection quality and BMS limits.

---

🔌 CHARGING REQUIREMENTS

The supplied specifications recommend a charge current of up to 155A.

• Bulk / Charge Voltage: 14.2–14.6V
• Absorption / Float Voltage: 13.4–13.6V

Compatible lower-output charging systems can also be used, although recharge time will increase as charger output decreases.

Your DC-DC charger, solar charge controller and 240V charger should all be lithium compatible and configured to suit the required voltage profile.

❓ QUICK FAQ

How thin is the Next Generation Ultra Slim 310Ah battery?

The battery body is approximately 85mm thick, with a stated overall installation thickness of approximately 89mm.

Where can the 310Ah Ultra Slim battery be installed?

It is designed for tight installations such as canopy walls, behind suitable seats, beneath false floors and other compact 4WD, caravan and 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 an inverter?

Yes, as part of an appropriately engineered system. The supplied continuous discharge rating is 330A, 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 155A. Lower-output compatible charging systems can also be used, but will increase recharge time.
