If weight is not an issue and extended run times are, consider the Big Dog of Block Battery’s Legacy Blocks. A DUAL voltage battery designed for cinematic or lighting production applications where two different voltages are required simultaneously; or for applications requiring voltage regulation to less than 28 volts. The D800 provides over 900 watt hour capacity with regulated outputs of 28 volts and nominal outputs @ 14.4 volts simultaneously. Block Battery D800 is a DUAL voltage battery designed for cinematic or lighting production applications where two different voltages are required simultaneously; or for applications requiring voltage regulation to less than 28 volts. The D800 provides an 800 watt hour capacity with regulated outputs of ~ 24 volts and nominal outputs @ 14.4 volts simultaneously.
