Battery for running a Bravo BTP12 Digital Pump
I'm gradually getting my kit together for a summer of boating!
I've a Yamaha STi 3.1 and have a nice shiny Bravo BTP12 pump.
I was intending getting a small battery for my 8hp Yamaha to run a few low power accessories, as the engine is fitted with a charging system. It occurred to me that perhaps I could use the battery as a 12v power source for the pump also, to save using the car and allow easier inflation of the boat at home (the drive is nowhere near the back garden!)
Is this feasible? If so, what size/capacity 12v battery would peeps recommend? I used to use a beefy leisure battery in my 18ft cabin cruiser days, but obviously want to keep weight and size to a minimum on a 3.1m SIB. My motorcycle has a 12v 5ah battery, but I'm thinking this size would be too small for the demands of the pump...
Any thoughts on this would be greatly appreciated. Over to you chaps!
