Alien Motion releases the AM16 with 16 cells of LiFePO4 power, in a practical, reasonably size case. This battery features increased capacity and starting power, with larger lower resistance terminals. The AM16 would be suitable for starting most Harleys, other large V-Twins, or snowmobiles. With a small footprint, less than 4 pounds of weight, and over 400 pulse amps, this is a seriously versatile battery.
