SMD does it again a powerful light weight starter box at a reasonable price.
This new SMD box has twin 775 motor's which have more than 50% more torque each than 540 motors found in lesser starter boxes. Twin 775's have more stalling torque than even the large single motor boxes around. In tests this box easily started a new engine which is the biggest test of power for any box especially in the cold winter months.
Can be powered by twin 7.2v stick packs or a 12v gel battery !
