If you’re craving the short recycle time of a flash powered by a Quantum Turbo Battery, but don’t have $400+ to spend, you’re in luck. SP Systems, a budget studio lighting manufacturer has a high-voltage battery pack for their AC/DC “Lancerlight” line. The SP Studio Systems Battery Pack with Charger is only around $125 and is compatible with Quantum Turbo cables. That means for $125, you can have 300 volts of light-generating power jacked directly into your Nikon SB, Vivitar 285, or any other flash with a high voltage port (most higher-end flashes have one and an associated Turbo cable).

The SP pack is larger than a Turbo 2×2, but it has the added advantage of using a Panasonic-style sealed lead acid battery pack (you know, the big camcorder batteries from the 80s)… they’re both cheap and easily available. It’s very easy to swap a new one in, even in the field.
