12v electric pump suggestions - Page 2

All I can say is that I've had my Yuasa 7Ah battery since 2010 and used it many times.

I've charged it when needed with a 1 amp charger.

The battery is really designed as a backup power source for alarms etc but it has so far been faultless as a power supply for my air pump, which draws well over 10 amps.

It gets left in the garage (frost protected) over winter and I charge it maybe a couple of times, when I remember to do it.

Now in it's fourth season of use it is still fine.....and it only me £15.

The yuasi batteries are sealed lead acid batteries...deep cycle traction cells the arnt BUT they will take plenty of abuse for a year or so then throw away and get another..there primary perpose is back up batteries for fire alarms and such like. They will charge fine off a 4 amp car battery charger...buy use abuse and replace..

the batteries to be used are model aircraft starting batteries, typical 7 amp batteries as shown above and 12 v trickle charger from machine mart £20
Had my 12 volt for 6 plus years and still all good

My first use of my new Bravo BTP 12v Digital pump didn't go well

The floor of my fast roller requires 11.3psi but the pump shows 4.3 psi and the plus and minus buttons won't shift it up or down. Have I just bought a faulty one or am I missing something obvious. I can't find a manual for it. Is there someway to reset the unit?

Probably no good for a 4.5m sib

but this looks cheap and it would be interesting to see it pump up a sib, I'm at decathlon soon so I'll check it out, but to be honest at £12.99 I'm not expecting much

Requires 4 LR 20 batteries:

This one looks a better at £28, obviously both will require you to finish off with your foot pump.

Sounds like you didn't buy a HP version needed for high pressure floors? The HP versions of the Bravo pumps will supply the >11psi needed for the fastroller floor.

Hopefully you still have time to swap under distance selling regs of have an understanding dealer.

This is the one I bought. Should be more than adequate

That does look right. The earlier version that I have (BST HP batt) had two (plus integrated battery options) versions, the BST for up to ~4PSI and the BST HP version for up to ~11PSI.

Is there an interlock to prevent accidental selection of the higher pressures that if accidentally selected would risk rupturing the tubes?

Also, you are trying to fully inflate the floor first on your fastroller before moving on to staged inflation of the tubes? I don't think this would create your issue but thought that I would check.

I don't think there is an interlock, I'll double check later. When I switch it on it goes straight to 4.3 and the plus and minus buttons won't change it.

I was inflating it floor first as per manual for the first time to fit launching wheels.

In terms of electric pumps no 'air movement' pump with a simple fan can give more than paddling pool pressure - these are all the cheaper ones - only a specific compressor type with a piston (ie the Bravo type) will get you higher pressures.

Does depend how often you need to pump it up and your budget - if pumping it up and leaving it up all summer then a Bravo is not really needed and a camp shop stirrup pump is fine but for those who pack away each time the Bravo is a great investment.

Upshot is you either buy an HP Bravo to do the whole job or use a basic electric airbed type pump for the voume and a double action stirrup pump for the final pressure.

Some info on budget options here:

I have one of these (not chargeable version) and it works well at getting the bulk of air in quite quickly!
I have got just about every pump going I can count 9 off the top of my head

Best all rounder is the Bravo BST 12 HP
next is you have mains power Bravo 220-500 240V Electric Pump
Bravo 220-500 240V Electric Pump - IBS Boat Supplies bit of a luxury but is always my chosen pump at home

The Bravo BTP12 will deliver 12psi no problem. It is rated to a maximum of 14psi.

The piston pump takes over after about 1psi.

When you turn it on the preset pressure is displayed. Hold down the plus or minus button until the pressure readout starts flashing, then you can adjust it using the buttons.

After you have set the pressure to what you want, wait for the display to stop flashing and you are good to go.
The pressure setting is memorized until you next want to change it.
