Single input DC-DC chargers do one thing, and one thing only: charge your aux battery from your alternator.
What is a DC-DC Charger?Ī DC-DC charger (also known as a battery-to-battery charger, or b2b charger) is a device that takes the input from your alternator/starting battery and uses it to charge your aux battery.ĭC-DC chargers are able to charge just about any type of battery (including lithium), they work with modern variable voltage alternators, and they employ multi-stage charging to fully and properly charge your battery bank.ĭC-DC chargers come in two varieties: single input and dual input. We’ll go over both in this post, but in general we recommend that most people get a DC-DC charger for their rigs. There are two kinds of devices for this: DC-DC chargers and Battery Isolators. So you need a device that allows you to charge a second (auxiliary) battery from your van’s alternator without draining your starting battery when the engine isn’t running. But paralleling your batteries means that when the engine’s off, your electrical loads will also drain the starting battery – not good if you want to start your van in the morning! You can easily use your alternator to charge your second (auxiliary) battery simply by connecting the positive terminals of both batteries so that they’re in parallel. An alternator is a device that converts the mechanical energy from your van’s engine into electricity, and uses that electricity to power electronics in your van and charge your starting battery.
