DIY with new generation Lithium Batteries?
Ok, there are many new high-powered Lithium battery sources. They use them for mopeds, golf carts, and for racing. I checked the specs of the Alien Bees, they are posted below:
===============
Vagabond II = 12v 20AH --- 13.25 pounds (heavy) --- 6.5" x 7" x 3" $300
Vagabond Mini = 14.8V 8.8AH --- 3.5 pounds --- 2.75” x 4.3” x 7.5” $240
===============
Now here is info for a Lithium battery that has the same specs as the Vagabond II, but is HALF the weight, but almost the exact same dimensions. And the Vagabond II is rated for 500 cycles... the Impact battery for 3000 cycles (that is the amount of times you can recharge it)
(1) - Impact Battery = $268
Voltage 10V - 17V
20 Hour Rate 20Ah
Dimensions 7.0 x 2.9 x 6.6
Terminal 8mm x 1.25
Weight 7.25 lb
*up to 3,000 cycles

They also make a 40Ah battery for $458
===============
So $268 for the battery, plus $40 for the charger... comes to $308, and you still need to buy:
(1) - 300-500 watt Pure Sine Wave inverter = $ ?
(1) - GFCI plug between the batteries and my strobes =$ ?
So, $350+ and you could build a Vagabond II... but with half the weight.
Not sure how reliable it would be, but then again I am guessing that it won't catch on fire
