Battery Box

[Phil Fargaze]

The other day I found myself at work with a nearly new car battery, an offcut of aluminium tread plate and with thanks to the credit crunch, a little bit of time on my hands. I had acquired a 12v hair dryer and dew strap recently and wanted a power supply for in the field situations. I found a spare fuse holder in need of a good home so the only expense was £13 for the 12v plugs. I checked the current draw for the dew strap and it was 1.7A. The current draw for the hair dryer was 0.6A on setting no.1 but the current draw for setting no.2 was a whopping 16A

Are you sure that hairdryer wasn't drawing one point six amps!!

[Phil Fargaze]

Good point. I`ll go off and double check!

[Phil Fargaze]

Just checked, and it was definitely showing 16 amps.

That's one HOT hair dryer!!!

Yeah ive got one of the mini 12v hairdryers and they def eat the current!

How do you make sure the battery doesn't slip upwards and short out against the lid. It could get a bit interesting if you haven't got a guard or something.

Nice project though.
