Talk Morgan Forums Community The Malvern Arms Help please - Battery current delivery?

Knowing that there are loads of clever types out there who know much more about this kind of thing than I, here's a question:

I am thinking of taking my Paddleboard somewhere where the Landy can't get to (more correctly, isn't allowed) so I'm thinking whether it's worth buying a small 12V battery to carry to power the electric pump. The pump is 110W and can inflate my board to 18psi in about 10 minutes.

Rounding out to 120W for 15 minutes suggests I need 2.5 AH. Allowing for inefficiencies, and possibly the need to inflate a couple of times, it would seem that a little 7 AH deep cycle battery like this would be more than adequate capacity wise:



But the question in my mind is: Would the battery be happy delivering 10 amps for 15 minutes without getting all hot and bothered? Part of me is theorising that they are used for things like rechargeable strimmers or mobility scooters so they should be ok, the other part of me is concerned that such a small light battery really might not be up to the job of delivering that much current even just for 10 minutes.

Of course, the alternative is to take the manual pump, but anyone who has manually pumped a paddle board up with one will understand why I'm asking the question
