If you are upgrading a home battery bank to lithium and you already have a modern charge controller, the process could be as simple as installing the new batteries and flipping a switch. If, however, you are replacing a lead acid/AGM battery with lithium in a vehicle or RV, then you must consider the capabilities of the alternator.
This will also help guide you through the installation process so you can quickly and safely install your lithium battery. If you’re aiming to replace your current lead-acid battery bank with a lithium iron phosphate (LFP) battery bank, there are a couple things that you’ll have to keep in mind before making the switch.
There are two main scenarios that might have you adding a marine battery to your battery bank: Scenario 1: You only have a cranking battery and you want to separate out the power used by everyday devices. Scenario 2: You need more capacity or more voltage for your existing house battery.
Disconnect the trunk that has all of your everyday devices, and leave the cranking battery hooked up to the motor exclusively. If you want an easy way to failover your new battery as a starter, install a four-position boat battery switch. Instructions will come with the boat battery switch.
The first step in upgrading a 12-volt lead acid battery to lithium is to choose the cell chemistry and configuration. This is a necessary step because regardless of the chemistry you use, lithium-ion batteries have a voltage that is much lower than 12. This makes it so you will have to put some amount of them in series to achieve 12 volts.
Lead-acid batteries are quickly becoming redundant. A growing number of customers are making the switch to lithium due to better performance and faster charging.

Maintaining Your Lead-Acid Battery
The capacity of a lead-acid battery is measured in ampere-hours (Ah) and indicates how much current the battery can supply over a certain period of time. It''s important to note that the capacity of a battery decreases over time, and the rate of decrease is affected by factors such as temperature, depth of discharge, and charging/discharging rates.
