> INSTALLING LITHIUM BATTERIES: FAQ 

Charging Your Lithium Battery

Giant Lithium Batteries don&#;t immediately need a special battery charger! Using your AGM battery charger is a temporary solution, not a permanent one. Wherever possible, a lithium battery should be charged using a charger with a lithium profile;  the nominal charge voltage for a 12v AGM battery is 14.1-14.4V, which means that using an AC to DC AGM battery charger that does not have automatic desulfation or equalisation modes and set to use the AGM setting will work correctly. However, it will only get your lithium battery to 95% charged.

We Suggest The Ardent 12V Battery Charger:

Using a 240V AGM charger is a temporary option until you can get a lithium-specific charger . Giant batteries are manufactured with a built-in high-quality 100AMP (BMS) Battery Management System that allows for most charger settings (15A)minimum (except flooded) to be used.

DC-DC Charging For Lithium Batteries

Regarding DC-DC Chargers and solar controllers, you must change these to LiFePO4-specific models, which can charge your Lithium batteries to an entire 100% State of Charge. The advantage of using a LiFePO4 charge profile is that it allows users to get the total capacity out of their lithium battery, as the DC-DC LiFePO4 setting will prolong the battery life. You need a DC-DC charger to effectively manage the power input in a lithium battery. **If you are charging from an alternator, you will need a DC-DC Charger that is designed to manage solar specific to lithium (LiFEPO4).
