FAQ’s
Can I swap my AGM Deep Cycle Battery for a Custom Lithium Battery?
The possibility of swapping your AGM battery for a Custom Lithium Battery primarily depends on your current charging setup. AGM and lithium batteries have distinct charging cycles and chemical properties. Lithium batteries, while lighter and more efficient with a longer lifespan, require more precise charging profiles to prevent damaging the battery and to prevent overcharging and avoid potential safety hazards.Before proceeding with a swap, it’s crucial to verify that your existing chargers and related equipment are compatible with lithium batteries. Ensure to consult the manuals for your DC-DC charger, solar charge controller, and 240V charger, among others. These should support the specific needs of lithium batteries to facilitate a safe and effective transition from AGM to lithium technology.
What size DCDC charger do I need for my lithium battery?
All the DC-DC chargers we offer are fully compatible with Custom Lithium Batteries. Whether you choose a charger with a built-in MPPT solar regulator or a straightforward DC-DC charger, you’ll find an option that suits your needs.The choice between smaller and larger DCDC charger models largely depends on your desired charging speed. For larger batteries, we recommend opting for a larger DC-DC charger to ensure more efficient recharging. However, even smaller batteries can handle a robust 40A charger for quicker charging. Alternatively, using a smaller DCDC charger, such as 25A or 30A, is also viable but expect slower charging times. If you are considering a charger from a third party or planning to use an existing one, make sure the lithium DCDC charger is configured to support a 13.4-13.6 volts absorption/float charge and a bulk charge of 14.2-14.6 volts to ensure optimal charging performance and battery health.
What charging profile should I use to charge my lithium battery?
For optimal performance, specific charging parameters need to be adhered to. The battery requires a charge voltage between 14.2V and 14.6V for effective charging. The absorption and float voltage should be maintained between 13.4V and 13.6V to ensure the battery is charged safely without risking overcharge.If your charger, like the Victron 12-12/30, offers a LiFePO4 setting, it’s advised to use this option to align with the battery’s requirements. This setting ensures that the charger outputs the correct voltage profile and maximizes the battery’s performance and longevity.
Are Custom Lithium batteries IEC-62619 certified?
All Custom Lithium batteries are made with high-quality IEC-62619 certified components and meet the AS/NZS 3001 recommendations.
How do I restart a flat Lithium Battery?
There are two main methods to restart an Ultra Slim Lithium Battery that has run flat:.
Method 1: The simplest method involves using a lithium-compatible 240V charger with a ‘power supply’ mode. Connect the Ultra Slim Lithium Battery to the charger, set it to ‘power supply’ mode, and allow it to charge until full. This method helps wake up the battery and continue charging.
Method 2: If you do not have access to a 240V charger, you can restart your battery using another 12V battery with similar voltage and capacity:
Equip yourself with jumper leads with positive and negative clamps. Position the two batteries next to each other, ensuring they do not touch. Connect the positive clamp of the jumper leads to the positive terminal of both batteries. Connect the negative clamp to the negative terminal of both batteries. Activate the vehicle or power source equipped with a DC-DC charger to start the charge. Once charging is confirmed, carefully disconnect the jumper leads, starting with the negative.
If your Ultra Slim Lithium Battery remains unresponsive after an extended discharge period, it may require servicing. Please return it to Custom Lithium for a professional assessment. It is highly recommended to fully charge the battery after a successful reset to ensure optimal performance.
