Charging your Batteries in the Car or with an InverterUpdated 3 hours ago

If you want to charge your FD battery from a car or mobile platform, here are some things to consider.

If you're charging from a normal Lead Acid or AGM car battery, a single Standard Assist PLUS 12.6 Ah battery can drain a car battery by at least 50% in just one charge - so you don't want to make your car go flat. It's best to have a 2nd battery installed in your car to avoid this. If you're looking for a 2nd battery, a deep discharge battery is preferred over a normal car battery as they are designed for cold cranking amps as opposed to sustained amp draw.

You cannot charge a battery from your normal 12V car cigarette lighter. Most cars 12V cigarette lighter plugs can't handle more than 100 watts sustained and your FD+ charger will draw about 160 watts sustained.

Really cheap, clipped sine wave inverters are not recommended as they have very poor power delivery and can damage electronics.

Assist PLUS batteries: Minimum 300W/12-24V inverter

Gen2 Standard and Fast Chargers: Minimum 500W/40V inverter

RedArc are a good brand, and is important to purchase a Pure Sinewave, of a reputable brand, and not a knock off Alibaba or similar.

Remember cars can get VERY hot inside when closed up and we do not recommend charging batteries inside a closed up vehicle as the charger or battery could get too hot. Always make sure the chargers have ventilation when being used.
