Power supply for dinghy pump

[prv]

Both of my boats are wired according to the manufacturers installation guidelines using 2.5 mm tri-rated cable which is rated up to 30 amps!

I'm sure yours are - my point is that you can't generalise from your boat to all the other ratty tillerpilot installs out there and say that "in most cases these are wired directly back to the battery and are fused with a 30 amp fuse". I've seen one wired with bell-wire off the lighting circuit!

Because we sometimes want to inflate a dinghy away from the boat we use (with a Bravo turbocharger -20A- pump) a portable 7Ah Sealed Lead Acid battery, in an insulated container.

They're way cheaper in a toy aeroplane shop, see here for example :http://www.sussex-model-centre.co.uk/shopexd.asp?id=919
