How to Charge Lithium Boat Batteries?

The most common way to charge lithium boat batteries is by using an AC to DC charger connected to shore power or a generator.

Charging Lithium Boat Batteries with AC to DC Chargers

An AC to DC charger is a popular and effective method for charging lithium boat batteries. It works by converting alternating current (AC) from sources like shore power or a portable generator into direct current (DC) which is what batteries need to charge.

Here's a breakdown of the process:

• Source of AC Power:

  • Shore Power: When your boat is docked, you can connect to shore power.
  • Generator: A portable generator can provide AC power when shore power is unavailable.

• AC to DC Charger Function: The charger takes the AC power and converts it into the correct DC voltage and amperage required by your lithium batteries.

• Connection: The DC output of the charger is then connected to your lithium battery bank for charging.
