You're welcome, Bazmondo.

Good to have 'real-life' experience of battery use, Lightning. Your results make sense - a 7Ah battery would, in theory, deliver 20 amps (a typical Bravo's drain) for just over 20 minutes. So, provided each inflation/deflation doesn't take longer than around 5 minutes, that's a good solution.

One possible word of caution - a 20 amp drain on such as small battery is quite tough going for a wee fellow. Does it get warm in use? Also, if it isn't designed as a 'deep-cycle' battery (one designed to cope with large discharging/recharging cycles), then you may find its life will be reduced.

Its portability is great, tho'.

I've had the battery for two years, it doesn't even get warm in use. I use a trickle charger to recharge the battery after I've been using it.
It says on the battery "valve regulated sealed lead acid battery"

I tested the current draw of the Bravo pump and it does draw about 20 amps but only when the piston pump kicks in at about 1psi.
Before that it's about 12 amps.

Before I got the Bravo pump I used it with my Rule pump.

The battery only costs 15 on ebay

You'll need some sort of charger to go with it, such as this one at 8
