Batteries and charging, simplified
Most boat electrical headaches come down to batteries that aren't charged properly. Here's how to set up a system that's ready every time you are.
AGM or lithium?
AGM deep-cycle batteries are affordable and tough. Lithium (LiFePO4) batteries cost more up front but weigh far less and deliver more usable capacity, which matters for trolling motors.
