LibertyPak recently introduced the new 33 volt, 24 amp battery belt designed exclusively for portable lighting. It is currently allowing gaffers to operate an LTM 200 watt HMI for over three hours on a single charge. With nearly 800 watts of power, it can also power a 400 watt Arri HMI for up to one and a half hours. Until now even the most powerful belts only lasted 20 minutes. LibertyPaks replace existing systems and save over 75% of the weight. Each pound holds nearly 100 watts of power, five times as much as conventional lead acid or NiMH. They are also much smaller. Three times as much power per cubic inch than other batteries. Also because LibertyPaks have no memory problems they may be charged as frequently as desired. Special internal circuitry protects against overcharging or over-discharging.
LibertyPaks can be 80% recharged in one hour.
