The Nano series from Fxlion are probably the smallest V-Mount batteries in the world. Small but nice because the batteries are also very powerful. With 50Wh up to 8 amps working current and with 98Wh up to 10 amps working current a lot of power for such a small battery. The batteries offer a D-Tap port and quite a few USB ports so you'll never run out of ways to power your devices. That said this is the regulated USB-C output which can charge your MacBook or any other USB-C compatible device. This battery like all of Fxlion's batteries has a built-in protection circuit that protects the battery and its electronic devices from overheating overcharging deep discharge and overcurrent. The battery is rechargeable and can be used at temperatures of -20C /+55C with a maximum loss at sub-zero temperatures of half the capacity. Two capacities are currently available: a 50-watt-hour Nano One battery and a 98-watt-hour Nano Two battery. An LCD display shows you the remaining capacity and voltage as well as the voltage from the USB ports. These ports are protected from dust and moisture by a rubber cover. In addition there are various accessories to the Nano batteries of course this is also in the compact Nano design.
