Not cheap, and requires a BIG powersupply as it doesnt have a built-in one, nothing that powerful has a built in one really, but you can buy them fairly cheaply, or make your own from an old PC powersupply (something in the 300-500watt range should be about right, but the more wattage the merrier).
You can also buy/make special harnesses to parallel two lipos together in order to charge them at the same time from a single charger, but its not ideal- better off with a pair of normal lipo chargers, tend to work out at roughly the same price:
£120 each for the bc6 chargers say, so total of about £250 once you add on the balance tap adaptors for each charger (£5 each or so).
vs
£200 for the duo charger, another £30-50 for a powersupply (at least, some of the higher powered models are upwards of a 100 squid ), plus import fees and shipping as you wont find those in the UK baring a miracle.
Nice thing is most can be ran from a 12v car battery, which is ideal for racing tracks with no mains power.
