Not that I know of. High current chargers are out there, but usually have one or two ports, and you can charge lipo's in parallel with a suitable adapter.
(FMA's MPA is an example of a relatively safe parallel charging adapter, capable of handling ~40A)
Limiting factors have to do with input power to the chargers, and are generally those related to 120v AC and the usual 15-20A branch circuit.
Lead Acid 12v batteries are also a limiting factor. Automotive batteries are designed for short term high amperage (starting)
and much lower current draw for longer terms. The 12v batteries that are much better to use are those intended for such things as trolling motors
Omni makes a series of batteries designed for such service. Expect to pay about twice the price, compared to a regular automotive battery.
