🔩 IMPORTANT MOUNTING RAIL INFORMATION

When installing the 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 rather than loading the bottom mounting rail.

⚠️ 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 equipment, 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 115A.

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

Compatible lower-output DC-DC chargers 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.
