Electrical Redesign – More Battery

As of the last revision of my camper’s electrical system, I had two battery banks with the ability to charge both and switch between them as needed.

Coachmen didn’t vent the fridge properly and issued a service bulletin to correct the venting. My glorious dealer claimed to have fixed the issue.

At the time, running the engine didn’t charge the batteries very quickly and running the generator was (and is) far tooContinue reading “Rooftop Solar – Magnetic Mount”

Charging a LifePo4 battery when the battery is below freezing or storing it below -4°F will damage the battery. Some batteries have built-in circuitry that cuts off charging at damaging temperatures and some have built-in heaters.Continue reading “Keeping my Lithium Battery Warm”
