[QUOTE="Doc Hudson, post: 443714, member: 1607"] Leisure batteries can be purchased from camping outlets, they are designed to keep the 12v caravan or boat electrics working while not connected up to a mains hook-up point. They have an Ampere/Hour rating. Which is how many amps they can supply for 1 hour.

Power (watts) = Voltage x Current. So (Power/Voltage) = Current. If you want 300w @ 12v, 300/12 = 25 amps. The power consumed by a Transformer or inverter is always a bit less on the output than the input, as no device is 100% efficient without any losses at all. So if you want 300watts, you should need something that can give at least 25amps per hour for the duration you want the Bowling machine to be working. Doc H. [/QUOTE]
