Lithium Iron Phosphate batteries have a few advantages over other batteries. They have a more constant discharge voltage that stays right around 3.2 volts during discharge and will stay at that level until the cell is exhausted, keeping power levels at full power until the battery is depleted. This feature makes it possible to eliminate any voltage regulation circuitry. With a 3.2-volt output, four cells can be placed in series to create a 12.8 volt output. Using phosphate helps to avoid environmental damage caused by the cobalt in other types of batteries. They can be recharged and they have a higher current or peak-power rating. There’s plenty more that comes with lithium iron phosphate batteries, but the real story is the Black PLB40 Portable Lithium Battery offered by Dometic.
The Dometic battery is designed to be used in rough situations where you need power, such as for your powered cooler or any other 12-volt appliances. For those going way off grid, the Dometic battery can be charged in your vehicle, with a solar panel, or using your home’s AC power. Charging rates can be monitored on the battery’s LCD display, which shows the battery capacity, charging/discharging status, and output status. It comes with a built-in 8A charger for rapid charging. USB ports on the battery can be used to charge mobile devices. A sturdy handle lets you carry the battery into your next location with ease. The battery has enough juice for an entire weekend, so you won’t have to worry about your device going dead while you’re out. The PLB40 has a life cycle that is up to four times longer than more commonly used lithium ion batteries. You can pick up one of these battery packs and keep the drinks cold and the music playing through Dometic or other retail sellers for $849.99.
