Thanks Paul

Hi Paul
Some more info re: your questions (albeit from a non sbig owner).
VA means a ratio between volts and amps.
1800VA means that at 1800 volts the current will be 1 ampere.
At 180 volts the current will be 10 ampere.
The battery will not be the same as a car battery which is a lead acid battery. It would probably be a Lithium , Cadmium , Nickel or Metal based battery.
A 12amp/hour battery of any type means that the battery will provide 12 ampere for 1 hour or 1 ampere for 12 hours.
The charging rates will differ from battery type to battery type.
Hope this is of some use to you.
Regards
Steve
